Latest / Wits & Weights | Strength & Fat Loss Over 40 / Walking vs. Running for Fat Loss and Longevity (Brad Kearns) | Ep 286
Transcript
- 0:01Philip Pape: If you've been hitting long runs and cardio sessions, hoping to get leaner, but you aren't seeing the fat loss results you want, this episode is definitely for you.
- 0:09Philip Pape: Former pro triathlete and Olympic coach, Brad Kearns, reveals how chronic cardio may be sabotaging your metabolism and making fat loss harder.
- 0:18Philip Pape: You'll discover why walking could give you far better results than running.
- 0:22Philip Pape: Learn about how running impacts your appetite and hormones, and understand exactly how to optimize your movement for both physique and longevity.
- 0:30Philip Pape: Welcome to Wits and Weights, the show that helps you build a strong, healthy physique using evidence, engineering and efficiency.
- 0:46Philip Pape: I'm your host, Philip Pape, and today we're challenging conventional wisdom about cardio and fat loss with Brad Kearns.
- 0:52Philip Pape: Brad is a researcher, coach, former two-time US national champion, number three world-ranked professional triathlete.
- 0:58Philip Pape: He placed second in last year's USA Masters National Championships in the 55 to 59 high jump.
- 1:04Philip Pape: His new book, Born to Walk with Mark Sisson, exposes the science behind why extensive walking, not running, aligns with our genetic blueprint for optimal health.
- 1:14Philip Pape: Today, you'll learn the metabolic reasons running can make fat loss harder, how it might make you lazier and tips for a more effective approach to cardio for fat loss.
- 1:23Philip Pape: Brad, thank you so much.
- 1:24Philip Pape: Welcome to the show.
- 1:26Brad Kearns: Hey, philip, I'm glad to be on.
- 1:27Brad Kearns: Great intro there.
- 1:28Brad Kearns: Thanks for spending the time and, yeah, we're going to roll up our sleeves and get into it, because we got some issues to discuss in the fitness world and it's been decades now of this programming message, of struggling and suffering your way to getting fit, that this is the path and it's time to unwind it, because so many well-meaning people have, you know, laced up their running shoes and, in the case of what we focus on in the book, but also, you know, devoted gym rats who are going in and taking a bunch of classes or immersed into the extreme CrossFit community and, by and large, following an inappropriate protocol that leads to breakdown, burnout, illness and injury and especially, failed efforts at reducing excess body fat and all kinds of other fallout, where the body is trained inappropriately and the results don't happen.
- 2:19Philip Pape: So let's go right for the jugular, because you took us there.
- 2:21Philip Pape: You mentioned some trigger words for people, I'm sure including CrossFitfit, which I did for like eight years before I switched the way that I trained.
- 2:28Philip Pape: What's wrong with running brad like what is wrong with it?
- 2:31Brad Kearns: uh, well, depends who you are, and it's really a wonderful outlet for people who are highly trained and well adapted and have that baseline physical fitness and musculoskeletal resiliency to enjoy endurance training.
- 2:46Brad Kearns: But it can easily lead to problems when you are not well adapted and you're coming from sedentary lifestyle patterns and then lacing up the shoes and heading down the road.
- 2:56Brad Kearns: So we need to look at running as a very dangerous, high risk sport because of the aforementioned fallout that I talked about.
- 3:06Brad Kearns: I talked to earnest high school kids who are competitive runners and then they get injured and their parent seeks me out to talk about my experience as a former elite level high school and college runner and pro triathlete and I say you know, you understand, like it's probably the second most dangerous sport on the high school docket besides tackle football.
- 3:25Brad Kearns: And it's this pounding and this prevailing approach where the obsession with repeatedly accumulating lots of miles day after day in the interest of getting fit for these ridiculous events that we glorify, like the 26.2 mile marathon.
- 3:44Brad Kearns: So it's inherently too stressful for the body and for most participants to gain any benefit from.
- 3:53Brad Kearns: Therefore, we have that tongue and cheek title of the book.
- 3:56Brad Kearns: We call it Born to Walk and it's a little bit of a take on the 2009 bestselling book called Born to Run, which glorified the amazing genetic attributes of the human for endurance.
- 4:06Brad Kearns: So we are indeed built for occasional magnificent feats of endurance as we are hunting down our prey on the savannah and evolving to the top of the food chain because we are able to access the big game and the nutrient-rich foods, and so that's part of our evolutionary biology that we are, for example, bipedal, so we are much better runners than a four-legged creature, and we have sweat mechanisms so we can persist and do endurance achievements in the heat where other animals might become overheated.
- 4:37Brad Kearns: We have an Achilles tendon, which primatologist Bill Sellers contends is quote the primary evolutionary adaptation that made human beings who they are, because our ape cousins, who don't have Achilles tendons if you go to the zoo and watch a chimpanzee decide to sprint across his area.
- 4:56Brad Kearns: He's running with this strange flat-footed style like a gorilla, and they're not well adapted for running any distance.
- 5:04Brad Kearns: And so we take this story and this message and then we have a very flawed misinterpretation and misappropriation to conclude that we are going to benefit from running long distances on the regular.
- 5:19Brad Kearns: So what happens when we get into overly stressful workout patterns and I'll define exactly how you can determine whether you're in an overly stressed pattern or not.
- 5:31Brad Kearns: But when we overstress ourselves with regular workouts that are slightly to significantly too difficult, that's when we incur these overuse injuries at an amazing rate.
- 5:41Brad Kearns: The stats on the running community are absolutely shocking and embarrassing.
- 5:46Brad Kearns: Yale University School of Medicine contends that 50% of all regular runners are injured every year and that 25% of all devoted runners are injured at any given time.
- 6:02Philip Pape: Yeah, I was going to get into that stat, so I'm glad you led with that, because two major things you brought up.
- 6:06Philip Pape: One is the injury rate.
- 6:07Philip Pape: I know soccer is another one that's way up there on the injury rate, which involves a lot of running but of course involves people crashing each other without equipment on, and I know lifting weights is at the bottom, if not the bottom lowest injury on the list, just so people are aware of that.
- 6:21Philip Pape: You also mentioned the genetic or ancestral factor.
- 6:24Philip Pape: Let's just talk about that for a second, because you made a great argument that it is a, not a red herring.
- 6:29Philip Pape: What's the logical flaw when people say, well, if our ancestors did this one thing, then it extrapolates to everything else, which we do, for food too, let's admit it, yeah.
- 6:38Brad Kearns: Yeah.
- 6:38Brad Kearns: And then you, you lead with sentences like wouldn't you think that blank, blank, blank, lead with sentences like, wouldn't you think that blank, blank, blank?
- 6:45Brad Kearns: And I'm like, well, maybe not, but since you loaded me up, I guess I have to think that way, yeah, so I guess it's out of context.
- 6:51Brad Kearns: Evolutionary biology insight.
- 6:53Brad Kearns: So indeed, if we went and looked at the Hadza in Tanzania one of the last remaining hunter-gatherer populations on earth they cover between three and nine miles per day in the course of their daily business gathering or out on persistence hunts.
- 7:06Brad Kearns: And so the human has long been engaged in frequent everyday movement, until only actually recent times, when you think of, like you know, the industrial revolution.
- 7:17Brad Kearns: Before that, we were mostly farming and moving on our feet, and even in factory life, people were working hard and moving on our feet, and even in factory life, people were working hard.
- 7:27Brad Kearns: That's why we have three meals a day, because you have to fuel up at breakfast to go and bust your butt in the factory.
- 7:30Brad Kearns: You got to take a midday break because you've been working so hard and then you come home and you want more food and we still have three meals a day for people that sit in front of a screen all day.
- 7:39Brad Kearns: So modern life is so different that we really can't compare to some hunter-gatherer anecdote and contend that we too can engage in persistence hunting day after day.
- 7:52Brad Kearns: And in fact, the ancestral pattern was completely different than what we perceive it to be, because if we were to fail at persistence hunting, we would be someone else's dinner.
- 8:04Brad Kearns: To fail at persistence hunting, we would be someone else's dinner.
- 8:08Brad Kearns: So we did not chase after the antelope for hours and hours and finally prevail because it got too hot.
- 8:11Brad Kearns: But we did that once in a while and then we carried the game back to camp and we celebrated and feasted for a long time.
- 8:18Brad Kearns: And hunter gatherers, by definition, did the bare minimum physical activity necessary to survive, whereas today we have a tendency to overexercise, especially in the running and the fitness communities where we push ourselves so hard.
- 8:32Brad Kearns: Because of all the confines and the comfort and predictability of modern life, we feel compelled to push and challenge our bodies, and that stuff is all great and it's a great way to live a balanced, adventurous, active life.
- 8:44Brad Kearns: However, the problem occurs when you overdo it and compromise your health, compromise your fat loss goals and get into these ruts where we see as a common pattern in the fitness scene.
- 8:57Philip Pape: Yeah, perfect segue to talk about metabolism expenditure.
- 9:00Philip Pape: There's a few concepts here that overlap we can maybe get into.
- 9:03Philip Pape: When you talk about the Hadza, first of all, what came to mind is how much honey they eat.
- 9:07Brad Kearns: I remember watching the documentary about that.
- 9:10Philip Pape: It's pretty cool.
- 9:10Philip Pape: But the idea of, for example, the constraint versus the additive model of expenditure you're familiar with Henry Ponser's work on that and the doubly labeled water study and then the fact that people overexercise I mean that is a key pillar we address on this podcast all the time is, a lot of people are doing too much and not enough of the right thing, and in my own nutrition coaching practice, plenty of a person, especially women, but I don't want to stereotype because men too will come in, just they're doing too much.
- 9:37Philip Pape: And then you step back, you strip it out, you focus on lifting heavy and walking and all of a sudden so many things start to normalize.
- 9:47Philip Pape: So how does this chronic cardio affect your metabolism, your ability to burn fat?
- 9:50Philip Pape: And then we can lead to what are the alternatives?
- 9:53Brad Kearns: Right.
- 9:53Brad Kearns: This constrained model of exercise asserts that we engage in an assortment of compensatory behaviors when we expend an excessive amount of energy exercising.
- 10:08Brad Kearns: I think it was Dr Herman Ponser's quote where he said reproduction, repair, growth and locomotion are a zero-sum game.
- 10:15Brad Kearns: So locomotion means all manner of movement and workouts and your workout patterns.
- 10:20Brad Kearns: And then if we dedicate too much energy to locomotion we turn down these important dials of repair, reproduction and growth.
- 10:28Brad Kearns: So that means the compensation theory of exercise means if you wake up your alarm at 6am and go slam a spinning class or run eight miles in the freezing, cold winter temperatures in Connecticut, the rest of the day your body is going to conserve energy because you expended so much with the workout, especially if the pace was incorrect, and we'll get into that shortly.
- 10:50Brad Kearns: But it also means that this exhausting, depleting exercise pattern that many fitness enthusiasts are engaged in will dysregulate appetite and satiety hormones.
- 11:01Brad Kearns: So the 6 am spin class is paired directly with reaching for the pint of Ben and Jerry's in the evening and wolfing the whole thing down.
- 11:10Brad Kearns: The body does not like to be depleted and exhausted on a regular basis and we kick into these survival mechanisms that prompt us to overeat, as if the brain is telling the body well, I better finish this whole pint in case this fool tries again tomorrow morning to wake up at 6 am and burn 750 calories at spin class.
- 11:31Brad Kearns: So that's the constrained model of integer expenditure as we turn down other dials.
- 11:36Brad Kearns: And the additive model, like you mentioned, is this long flawed notion where you can go on the internet and calculate your basal metabolic rate and then go determine that a spin class burns between 650 and 700 calories and then add that up and, as the calculation finishes here, you should lose 42 pounds of excess body fat in one year because you're doing spin class three days a week and obviously we've learned that that's a disastrous, dismal failure.
- 12:03Brad Kearns: But to continue on this rant, to answer your question, what happens when you engage in overly stressful endurance exercise patterns is that you chronically overproduce stress hormones and they linger in your bloodstream, just like they do in our hectic, high-stress modern life.
- 12:20Brad Kearns: So we already have stressful lifestyle patterns that are in disconnect with our ancestral model and our genetic expectation for health.
- 12:28Brad Kearns: And now you layer on top that 6 am spin class or that long distance run and that 30 miles a week that you're trying to hit, and then work it up to 40 miles a week before the marathon comes in the final months, and what happens is it's stress on top of more stress, and when you put out too much cortisol people are familiar with that term as the preeminent stress hormone when you do that routinely, your body gets the signals, the genetic signals are sent to add body fat and shed lean muscle mass and, in particular, you are prompted to store visceral fat.
- 13:03Brad Kearns: That's the health destructive fat that collects around the organs, even worse than the subcutaneous fat, which is stored all over in your problem areas and is largely.
- 13:11Brad Kearns: It's not a big health concern, but the visceral fat has immediate destructive effects to your overall health and your hormone balance.
- 13:19Brad Kearns: And this is what happens to endurance freaks that train too hard and push their bodies without that balance of stress and rest and also a more varied fitness program where, like you say, you're doing the low-risk activities like lifting weights are far more safe than just jogging down the road with your elevated, cushioned shoes.
- 13:39Philip Pape: And I want to put a pin in a topic to get to later, if we don't forget, because I do want to address the corner case of the person who can do a high level of endurance activity and balance things out.
- 13:49Philip Pape: I want to talk about that but in the meantime, a few things just to clarify for folks listening because you put that so clearly is, if you're trying to burn an extra 100 calories from more activity, you're probably going to offset a fraction of that, if not the whole thing, through this compensatory mechanism.
- 14:07Brad Kearns: Yeah, philip, when I worked for a spinning company, the spinning indoor cycling program, my friend Johnny G invented spinning and we were trying to educate consumers about different things and so we actually funded a study to see what the calorie burning was like.
- 14:22Brad Kearns: And a spin class burns around 650 to 700 calories in that 45 minute class.
- 14:27Brad Kearns: And then I did a macronutrient analysis of a Jamba Juice medium smoothie and a breakfast scone and it was like 710.
- 14:37Brad Kearns: So you're going at 6am if you do a spin class, you're going to be tending to reaching for that extra food to replenish depleted glycogen.
- 14:47Philip Pape: Yeah, and guess what, if you're tracking and you use willpower or discipline to not do that, then you're just going to be starving.
- 14:53Philip Pape: So it's just either way right.
- 14:55Philip Pape: It all works out one way or the other, and this is why I like the body, treating the body as a closed system.
- 15:00Philip Pape: Because you mentioned BMR calculators and people know the pie charts that have BMR, thermic, effective food, exercise and non-exercise, and they try to add it all together and really what you should do is okay, this is what I'm eating, this is how my weight is changing.
- 15:16Philip Pape: Therefore, I know how many calories I'm burning.
- 15:17Philip Pape: And that's effectively what Ponser and the guys did is, they said, almost everybody on the planet has roughly the same BMR when normalized for muscle mass, when normalized for body composition, and so that's not going to be an efficient way to burn more calories, and I know we're going to get to one.
- 15:31Philip Pape: That is that everybody knows we're going to talk about, which is walking.
- 15:35Brad Kearns: On that note, I came up with some interesting research in the course of writing this book, which was really fascinating.
- 15:40Brad Kearns: Someone who is sedentary and unfit this is the sitting is the new smoking body of research.
- 15:47Brad Kearns: But what's happening there is that they are engaging overactive inflammatory processes and stress reactivity end quote.
- 15:57Brad Kearns: I'm remembering this, burned into my brain.
- 15:59Brad Kearns: So they are burning energy in an inappropriate manner.
- 16:04Brad Kearns: And the analogy that was brought up was like the firefighters are in the station and they're not getting any calls on the truck and so they're racing up and down the stairs and then they're coming over to your house just for practice and so they bash in your front door and they run up around and they also put an ax into your stairway and then they go back to the station and rest and then do it to someone else's house.
- 16:26Brad Kearns: So we don't want these overactive inflammatory processes and stress reactivity, but that's what's happening if you do insufficient exercise and don't burn the calories in the correct manner through extensive everyday walking and dedicating yourself to an appropriately designed fitness program.
- 16:44Brad Kearns: And that's again because you mentioned the ceiling.
- 16:47Brad Kearns: It made me think of that and like, wait a second, how is my unfit, lazy neighbor burning the same number of calories per day, as I am.
- 16:54Brad Kearns: When I'm going to these, 6 am spinning classes.
- 16:57Brad Kearns: Some of it is devoted to the body not working right.
- 17:01Philip Pape: Yeah, it is fascinating when you look at walking versus standing and not being sedentary versus cardio versus lifting and when you kind of combine the best of those.
- 17:12Philip Pape: I was just talking to my coach the other day about having better work capacity and conditioning when you're a lifter.
- 17:18Philip Pape: Are there benefits to that from a nutrient partitioning perspective?
- 17:21Philip Pape: And there is evidence that shows that if you're trying to build muscle, for example, and you're in a calorie surplus, a little bit more of that will go toward muscle.
- 17:28Philip Pape: If you're a little bit better conditioned, it doesn't mean doing a bunch of cardio.
- 17:31Philip Pape: It just shows how, like we're kind of meant to be fit people.
- 17:34Philip Pape: You know doing things.
- 17:36Brad Kearns: Yeah, and also, uh, you're probably familiar with Chris Hinshaw.
- 17:39Brad Kearns: He's a big coach in the CrossFit scene, his business is called Aerobic Capacity and he's a former compatriot of mine on the professional triathlon circuit.
- 17:48Brad Kearns: So we both had that extreme endurance background Now, you know, transformed into he's a big CrossFit guy and I'm a sprinter and a high jumper in Masters track and field.
- 17:57Brad Kearns: But he was discovering when he started working with the CrossFit athletes that these guys are so powerful and explosive and have the amazing ability to do 10 box jumps and then climb the rope and then do some upside down handstand pushups.
- 18:12Brad Kearns: However, with the lack of that baseline endurance or that baseline aerobic capacity, they're going to do this amazingly impressive workout and bomb out in 17 minutes instead of 31.
- 18:24Brad Kearns: And they're going to get eliminated in the CrossFit Games regionals instead of going to the finals.
- 18:29Brad Kearns: So every athlete in every sport obviously the elite soccer players and the NBA players who are running up and down the court everyone needs this aerobic foundation in order to thrive and perform, even in the most explosive events.
- 18:44Brad Kearns: A power lifter okay, the most explosive sport of all where your effort is four seconds long, the longest thing they're asking you to do is lift the weight off the ground.
- 18:53Brad Kearns: But how long do these guys' workouts last?
- 18:55Brad Kearns: They last for hours.
- 18:56Brad Kearns: They do a two and a half hour weightlifting session.
- 18:59Brad Kearns: So as soon as you get out of the car and walk through the parking lot to the front door of the gym and beep your pass and get your towel and head over to the weights and do a warm-up set and then sit and go through your text messages, which apparently is part of gym culture these days.
- 19:14Brad Kearns: And I often wonder because I'm not a big gym guy, philip, but I'm like I see a guy on the bench press machine that I want to use, but he's resting between sets and sending text messages.
- 19:24Brad Kearns: Is it okay to say hey?
- 19:30Philip Pape: can you text like one bench over, so I can do my one set and move on with my life.
- 19:32Philip Pape: It is okay.
- 19:32Philip Pape: It is okay.
- 19:32Philip Pape: It's a genetic to say can I work in there?
- 19:33Philip Pape: Yeah, you should tell him to pace around, get some steps, yeah exactly, but I'm making the point.
- 19:39Brad Kearns: It's like as soon as you get out of your car car your heart rate is at least double resting rate, and spiking up even higher when you're doing sets.
- 19:47Brad Kearns: But when you're sitting on the bench texting it's still double resting rate.
- 19:51Brad Kearns: So you are getting a cardiovascular training effect for that entire hour and 45 minutes that you're goofing around in the gym in between doing hard stuff, and so that counts toward your cardio quotient to the extent that you don't have to go and pound out miles on the road to hit that checkbox on your total fitness scoreboard.
- 20:14Philip Pape: Yeah, that's right Because, again, I used to do CrossFit and you get conditioned but you also burn out and if you look at the competitors, they also focus a lot on their strength and their exercise.
- 20:25Philip Pape: You know their movements to where they have a strength base as well, such that the cardio, the conditioning for them, visceral fat.
- 20:31Philip Pape: But you mentioned something specific.
- 20:32Philip Pape: You said it can break down muscle tissue, I believe, which means it's catabolic, and people love to understand, or don't always understand, that concept of anabolic behaviors eating anabolically, having higher energy flux through walking that it's anabolic.
- 20:54Philip Pape: Recovering is anabolic, Hormones are anabolic, but catabolic is the opposite.
- 20:59Philip Pape: I don't know where you stand on carbs.
- 21:00Philip Pape: This is just a side tangent, but I often talk about how sometimes carbs can be anti-catabolic when you're building muscle.
- 21:06Philip Pape: But anyway, that's a separate topic yeah, well said, exactly.
- 21:09Philip Pape: Yeah, yeah.
- 21:10Philip Pape: So I know you said walking is anabolic and running is catabolic, so maybe explain that a little more for folks.
- 21:16Brad Kearns: Oh, my goodness, that's so funny.
- 21:17Brad Kearns: You bring up this because Mark and I spent probably a week talking back and forth to add a couple paragraphs to the book to explain it properly, and it's so complex, but we want to give you the simple insights.
- 21:30Brad Kearns: But just as a background, like body is, it's an oversimplification to say this is catabolic, this is anabolic, but it makes the point really well.
- 21:37Brad Kearns: But at all times the body's undergoing processes that are both actually and the best example is sleep.
- 21:44Brad Kearns: So sleep is called an amphibolic process because you are both engaging in catabolism as well as, of course, anabolic.
- 21:53Brad Kearns: Uh, when you talk about, you know restoring and repairing and regenerating with your overnight sleep.
- 21:59Brad Kearns: So with walking, it is sending signals to the body for anabolic processes because it's minimally destructive, you have minimal impact, trauma and you're getting all these processes working.
- 22:11Brad Kearns: Where you're getting more blood flowing, oxygen delivery, you're building a brain-derived neurotropic factor to help with neuroplasticity.
- 22:18Brad Kearns: So all this great stuff is happening with minimal penalty or destruction or breakdown.
- 22:23Brad Kearns: Now with running overall for most runners, because they are not fit enough to really do the sport in a manner that is minimally stressful and building the aerobic system, they're just breaking down the body over and over with a slightly too stressful pace and also incorrect form.
- 22:43Brad Kearns: That's resulting in more impact trauma, because what we see this pattern is the over-striding, breaking, jarring heel-striking pattern as seen in 80 to 95% of all recreational runners, according to Dr Daniel Lieberman's research at Harvard percent of all recreational runners, according to dr daniel lieberman's research at harvard.
- 23:02Brad Kearns: And so the reason that we see so much of this overstriding braking pattern are people that are poorly adapted, have insufficient overall physical competency and musculoskeletal resiliency to run with correct form.
- 23:15Brad Kearns: Why are they running or how are they able to run?
- 23:19Brad Kearns: It was the invention of the elevated cushion shoe back in the 1970s by Nike.
- 23:24Brad Kearns: So these shoes came out where you could put on the shoe and shuffle down the street with this heel striking pattern and go and run five miles, whereby, if you didn't have these magical shoes, you'd be traumatized after two minutes or three minutes and your calves and your feet would hurt because of the poor running form.
- 23:42Brad Kearns: So the shoes enable poorly adapted people to run who should not be running in the first place.
- 23:49Brad Kearns: Do they cause poor form?
- 23:51Brad Kearns: Of course not.
- 23:52Brad Kearns: It's an innate object that sits on a shelf and so what they do is enable poor form.
- 23:57Brad Kearns: What's the cause of poor running form.
- 23:58Brad Kearns: It's that lack of basic physical fitness.
- 24:02Brad Kearns: So you have tight hip flexors, you have tight hamstrings, you have dysfunctional glutes because they don't fire, because your form is incorrect.
- 24:11Brad Kearns: You have poor core strength and poor foundation, so that you have an insufficient forward lean of the trunk, so you're allowed to do this breaking stride.
- 24:19Brad Kearns: You have poor ankle mobility and all these factors against you because you're not a super fit person and you have a lot of sedentary patterns in life.
- 24:27Brad Kearns: And then you insist on shuffling down the road at this dangerous sport that is gonna drive chronic overuse injury.
- 24:35Philip Pape: Because it's so easy, right?
- 24:36Philip Pape: You just lace up your shoes, no equipment needed, and you just go.
- 24:39Philip Pape: Yeah, so I know the shoes in the 70s and I believe there was some book in the 70s too, that I don't know if you know which one it is that led to a huge the fitness revolution, or whatever.
- 24:49Brad Kearns: what came to running this running boom kicked off, and it's important to understand, because there's been so much hype and marketing commentary socializing us to think that running is this end all fitness accomplishment, when in fact it's, you know, mainly catabolic and prompts accumulation of fat rather than reduction of fat and prompts the loss of muscle.
- 25:14Brad Kearns: And boy, we really got into this mess with profit driven corporate marketing forces with a big interest in it, especially the running shoe advertising Just do it is widely regarded as the greatest advertising campaign of all time, and so, hey, how can you resist?
- 25:30Brad Kearns: And I want to clarify that, like getting people off the couch in comfortable modern life and out, doing something is a great step forward for mankind, but it's really important to do it correctly, otherwise we can actually be worse off than someone who just engages in a basic level of activity, like tending to their garden and walking down to the post office to mail a letter, and all those quaint memories that we have from a previous time, before the fitness boom kicked into gear.
- 25:58Philip Pape: Yeah, so we addressed some of the reasons why running is not great for fat loss.
- 26:02Philip Pape: Not only that it breaks down muscle tissue, but you also compensate for the calorie burn.
- 26:08Philip Pape: It also causes overtraining, which means you're not going to be moving as much or you're going to impede recovery.
- 26:14Philip Pape: But just to make it super clear for people I know there's this idea running makes you tone, it burns fat.
- 26:19Philip Pape: It's just part of that culture.
- 26:21Philip Pape: Why is just that not the case?
- 26:23Philip Pape: Just so people know.
- 26:23Philip Pape: Like the big bullet points behind that.
- 26:26Brad Kearns: Well, it's not a very demanding sport for the overall musculoskeletal system.
- 26:31Brad Kearns: Right, you're just shuffling down the road.
- 26:32Brad Kearns: Go look at the elite runners in the Olympics.
- 26:35Brad Kearns: These guys are super skinny and somewhat emaciated, but they're also ripped and they're fine athletes and they're running at a very, very high speed.
- 26:44Brad Kearns: So it's sort of like a different deal when you look at a guy who's running a two-hour marathon or running the 10K around the track in 26 minutes.
- 26:53Brad Kearns: They're extremely highly trained athletes and very fit and have the physique of a champion.
- 26:59Brad Kearns: So the recreational aspect, where people are running very, very slowly.
- 27:04Brad Kearns: However, they're still stressing their bodies too much with the simple act of running that they're not adapted to do.
- 27:11Brad Kearns: So it's kind of like pushing yourself to do a bunch of deadlifts, of squats with really crappy form and continuing and insisting to continue and do more and more sets until you're really tired and your form's even worse, and then you get injured and exhausted and reach for the Ben and Jerry's.
- 27:29Brad Kearns: We wouldn't dream of doing that, that stupid of a workout in the gym, but basically that's what we're seeing every day when people are going for that weekly mileage goal, with that poor form, with that excess impact, trauma and the overeating and the appetite and satiety dysregulation that occurs from overly stressful pattern.
- 27:50Brad Kearns: And one thing when you listed off those reasons that were criticizing running, we forgot another huge one, which is, if you're devoting all this energy to cardiovascular endurance training at a slightly to significantly too stressful of a pace, guess what you don't have time and energy for anymore.
- 28:08Brad Kearns: You don't have time to even dabble in weights and go do one set through the machines once a week, or the very bare minimum necessary to maintain functional muscle mass and muscle strength, and forget about probably the greatest return on investment of any workout known to mankind, which is sprinting right.
- 28:26Brad Kearns: So the brief, explosive, all out sprints are the thing that we lose more quickly with aging than we do the cardiovascular endurance.
- 28:36Brad Kearns: I talked to my mom about this.
- 28:37Brad Kearns: She's 87.
- 28:38Brad Kearns: She's in fantastic shape and she walks one to two miles every morning with her dog and she's very proud of it and looks around at people her age who are falling apart and I say, hey, that walk is great, that's a great foundation.
- 28:49Brad Kearns: Now you need to keep that appointment with the personal trainer at the gym and you need to go put your body under resistance load to maintain that muscle mass.
- 28:57Brad Kearns: It's absolutely essential and I think you know it's nice to see now with the content you're putting out and many other people like strength training and sprinting are vastly more important than this baseline cardiovascular steady state endurance training Because, as I mentioned, you are getting cardio if you become a competent strength trainer or a sprinter.
- 29:19Philip Pape: Okay.
- 29:19Philip Pape: So you opened the door to sprinting because I wasn't even going to go there.
- 29:21Philip Pape: I was next going to say okay.
- 29:23Philip Pape: So we know pretty much for a fact that you could lose fat, be fit, not have to run ever.
- 29:28Philip Pape: Trust me, I know from personal experience and coaching many, many clients who don't want to run and they don't have to run.
- 29:33Philip Pape: But sprinting is its own form of running, in its own category, and I will say I love it.
- 29:40Philip Pape: I don't do it as often as I used to.
- 29:41Philip Pape: Again, in CrossFit, my favorite thing to do was shuttle runs.
- 29:44Philip Pape: I love the ones where the every minute on the minute where you had to do like I don't know, I think it was 10 meters, and then on the second minute you do 10 meters and then 10 meters back and then on the third you add another segment.
- 29:54Philip Pape: You see, if you can get up to like 18 was a pretty good.
- 29:57Philip Pape: Like you know, I have an ego.
- 29:59Philip Pape: I'm satisfying my ego right when you get to like 18, but let's dive into that then, because I don't talk about that enough on the show.
- 30:06Philip Pape: I'm not against it.
- 30:06Philip Pape: I talk about things like pushing and pulling sleds.
- 30:09Philip Pape: We talk about if you need to go on the bike or do some swimming or something that is completely concentric without the eccentric loading.
- 30:18Philip Pape: That's cool, you know, for a session here or there, but tell us about sprinting.
- 30:22Brad Kearns: Well, if we had more space on the cover, the book would appropriately be titled Humans Are Born to Walk and Sprint.
- 30:29Brad Kearns: Okay, and so that is.
- 30:30Brad Kearns: Our essential genetic expectation for health and survival is that we need to be prepared.
- 30:36Brad Kearns: In primal times we need to run for our lives or run to get food so we didn't starve, and so that selection pressure, the genetic adaptations occurred where we became great endurance machines, as discussed earlier, and we also became very strong and we became powerful and explosive to deal with a primal hazard.
- 30:56Brad Kearns: So we want to honor those genetic expectations for health today, and sprinting is a hugely important piece of the puzzle.
- 31:04Brad Kearns: Interestingly, it doesn't take that much time, so it's not a huge ask to have someone sprinkle in some sprinting stimulation into their fitness regimen.
- 31:14Brad Kearns: And we're talking about when we really use the term sprint properly.
- 31:18Brad Kearns: We're talking about a brief, explosive, nearly all-out effort, and we know from exercise physiology the human can only deliver a maximum effort for seven seconds.
- 31:28Brad Kearns: Right, that's what the ATP, creatine, phosphate, the energy inside the cell where you can go full bore, starts to peter out at seven seconds, and so anything over seven seconds is not technically a pure sprint.
- 31:41Brad Kearns: So when we watch the 100 meters in the Olympics and the guys run 9.79,.
- 31:45Brad Kearns: They're actually decelerating a bit in the final stages of even the fastest, most explosive event in the Olympics.
- 31:52Brad Kearns: So that's something to understand when we talk about sprinting.
- 31:56Brad Kearns: The ideal template for a workout would be to sprint for 10 to 20 seconds.
- 32:01Brad Kearns: Yes, sprinting for seven seconds is great, but if we get 10 to 20 seconds then we're getting some good fitness stimulation.
- 32:07Brad Kearns: But we're stopping before we incur too much cellular stress and musculoskeletal trauma and stress hormone production because the workout's too brutal and your tongue's hanging out at the end.
- 32:20Brad Kearns: So a proper sprint workout is not Rocky Balboa puking on the side of the road from going so fast so many times.
- 32:28Brad Kearns: It's a very crisp, explosive session where you're executing precise technique and you do not degrade over the course of the workout.
- 32:38Brad Kearns: So, unlike high intensity interval training where you're hanging on and you got two more and you can do it and the group is rallying around you and you high five at the end as you're dripping in a pool of sweat during that spin class where you're asked to go over and over again for 30 second sprints with 30 seconds rest and we're going to go for it, that's one form of training but true, sprinting is an extensive amount of rest in between very brief bursts of all out performance.
- 33:07Brad Kearns: So I give this recommended template for anyone could be a four to eight sprints lasting between 10 and 20 seconds, with a minimum six to one recovery to work ratio.
- 33:20Brad Kearns: So if you're sprinting for 10 seconds, you rest for at least a minute before you do another sprint and that gives you this consistent quality of high performance effort with each rep.
- 33:30Brad Kearns: You only have to do four to eight.
- 33:32Brad Kearns: Oh question, in the back of the class, what if I get really good and fit and I do eight good ones?
- 33:36Brad Kearns: Then what you're going to do is you're going to go faster.
- 33:39Brad Kearns: You're not going to go up to 12 someday or 14, or keep adding volume, as we've been socialized to believe inaccurately by fitness programming where it's like more, more, more.
- 33:50Brad Kearns: With sprinting it's all about quality and extensive rest and, as you read on my bio, now that I'm a master sprinter and having to learn all the attributes of sprinting that weren't familiar to me as a longtime endurance athlete, I'm getting scolded by my advisors because I'm only taking a six to one ratio, which I feel is plenty for me.
- 34:12Brad Kearns: But to do to get fast at 10 second sprints, you might want to rest for two or three or four minutes before you do another one, and that's just a more sophisticated level of sprint training.
- 34:22Brad Kearns: But for the basic template for everybody is that four to eight sprints, 10 to 20 seconds, six to one ratio, and then you're opening up a whole new world of fitness benefits.
- 34:33Brad Kearns: Especially, and probably of most interest to people, is the ability to shed excess body fat quickly, especially visceral fat, and there's great research showing that sprinting targets visceral fat reduction in particular, because visceral fat is more metabolically active than subcutaneous fat, so it makes it easier to remove if you send the right genetic signals through things like sprinting or I guess you could arguably throw in fasting and things like that that are trying to rev up the metabolism.
- 35:06Philip Pape: I have to say, brad, you've got the bug in me all right, so I got to do this now Because you're right, the way I used to do it was more of the HIIT style that you're talking about, and I absolutely love this prescription and the caution to only go up in intensity, only go up in speed, as your form of progressive overload for your sprinting is really good, because then people aren't doing oh, now I'm doing 12 of these, now I'm doing 20.
- 35:29Philip Pape: Guess what?
- 35:30Philip Pape: My Brad Kearns protocol is now an hour long.
- 35:32Philip Pape: It doesn't work that way.
- 35:33Philip Pape: This is good.
- 35:34Philip Pape: I'm going to follow up on this with you later and then this could be a whole separate topic to dive into.
- 35:39Philip Pape: All right, cool Sprinting, brad.
- 35:41Philip Pape: Good, everybody has that.
- 35:43Brad Kearns: Oh yeah, sprinting is definitely a full show dedicated to that.
- 35:48Brad Kearns: And when we look at these research benefits like brain-derived neurotropic factor and just making you a more confident, resilient person, and also what sprinting does is it reduces perceived exertion at all lower levels of exercise intensity.
- 36:03Brad Kearns: So if you become competent at sprinting, your five mile jog or your hour long group exercise class in the gym, everything feels easier and it literally is easier because, as you know from like central governor theory, your perception of how difficult the workout is is how difficult the workout is.
- 36:23Brad Kearns: And so when we say my quads got really tired on my 12th rep of squats, it's not literally true.
- 36:30Brad Kearns: The quads don't have feelings and emotions and think they're tired.
- 36:33Brad Kearns: It's your brain that gets tired because you never worked that top end, and so everything becomes sort of a challenge or grueling or all these sensations where we need to teach the body to perform that brief, explosive, powerful as the essence of anti-aging.
- 36:49Brad Kearns: So the anti-aging benefits are tremendous and, in contrast to that chronic overproduction of stress hormones that I talk about with an endurance training regimen, what sprinting does is an appropriately brief fight or flight spike of hormones into the bloodstream and then, because the workout is over quickly.
- 37:07Brad Kearns: You're able to quickly recalibrate back to homeostasis and come back stronger and more resilient, thanks to testosterone and growth hormone coursing through your bloodstream, acting upon target organs, building more muscle, shedding excess body fat and improving the brain's perception of fatigue during exercise.
- 37:29Philip Pape: Yeah, the mind-body thing is really powerful there you mentioned.
- 37:32Philip Pape: This reminds me a lot of just the system we use for lifting right, it's the ATP-CP system, and if you look at the physique of sprinters, you know that they're not emaciated like long distance runners.
- 37:47Brad Kearns: Yeah, there's a popular quip when we're doing live lectures and you ask have you ever seen a fat sprinter?
- 37:55Brad Kearns: And the answer is no.
- 37:56Brad Kearns: There's no such thing, because it's the penalty for carrying excess body fat when you're going at high speed is so severe that the genetic signaling will occur every time you do a sprint workout to shed that excess body fat, to adapt and become stronger for next time.
- 38:12Brad Kearns: Now, have you ever seen a fat marathon runner?
- 38:14Brad Kearns: In fact, the research from Cape Town Marathon in South Africa determined that 30% of the participants were over the healthy BMI range.
- 38:23Brad Kearns: And then we compare contrast to World Health Organization research showing that 30% of the global population, largely in the developed nations, is also outside of healthy BMI range.
- 38:34Brad Kearns: So when you go to an event and you cannot distinguish between the spectators and the participants, you got a problem with your sport.
- 38:43Brad Kearns: You go to a powerlifting meet I can see who's competing in the heavyweight division and who's watching, but the marathoning generally does not support any improvement in physique and can actually cause extreme harm with that accumulation of visceral fat and the loss of muscle mass.
- 39:02Philip Pape: Yeah, and I know when I've sprinted and I've asked people to just do it randomly who are lifters, who squat a lot, it's like that base of power goes a long way as well.
- 39:10Philip Pape: They're a duo, they're like.
- 39:12Philip Pape: Batman and Robin.
- 39:13Philip Pape: There, it's cool.
- 39:14Philip Pape: Yeah, it's pretty cool, all right.
- 39:15Philip Pape: So on the other side of the spectrum, you posted something on Instagram just recently, a few days ago that said endurance running the way most people do it prompts increased laziness in general life, and I'm very intrigued by that.
- 39:27Philip Pape: I want you to tell me more about that one.
- 39:29Brad Kearns: Yeah, it happens both consciously and subconsciously.
- 39:33Brad Kearns: So when you're proud of yourself for waking up on the cold, snowy morning and running eight miles before most of your neighbors are awake, or they're shuffling out to pick up the newspaper and head back into the warm home, what happens is you give yourself permission, you give yourself a hall pass to be lazier throughout the day.
- 39:51Brad Kearns: And so when you're asked, hey, do you mind raking the leaves this afternoon?
- 39:57Brad Kearns: You say I'll do it tomorrow because I ran eight miles this morning and I'm tired and lazy.
- 40:02Brad Kearns: So, on a conscious level, you give those hall passes for another scoop of ice cream, another serving, another helping at the meal, and runners glow and crow about how they have a free pass to eat more food.
- 40:20Brad Kearns: And you were mentioning the books that helped launch the running boom.
- 40:22Brad Kearns: One of them was the complete book of running by Jim fix, who famously dropped out of a heart attack at age 51, ignoring all recommendations to get medical checkups, even though he had a family history.
- 40:32Brad Kearns: And he would write passages like the great thing about running is when the furnace is hot enough, anything will burn.
- 40:38Brad Kearns: In other words, you don't have to scrutinize your dietary choices because you're burning so many calories.
- 40:43Brad Kearns: And this became a cultural paradigm in the seventies.
- 40:48Brad Kearns: And even the leading cardiovascular experts at the time the doctor, said the same thing they thought you would be heart attack proof if you could run a marathon and now're seeing the opposite a rash of heart problems in long-time extreme athletes.
- 41:01Brad Kearns: But back to the permissions where consciously you give yourself those hall passes and then subconsciously the body engages in these energy conserving mechanisms to react to what's perceived as a survival threat and so you need to conserve energy.
- 41:18Brad Kearns: You turn down those other dials, remember they are reproduction repair and growth in favor of excess locomotion.
- 41:26Brad Kearns: And I think the most extreme example when we talk about reproduction for males that would mean one's libido and for females, reproductive fitness can go awry with these extremely high-performing females when their body fat drops below a threshold and they experience amenorrhea, the loss of menstruation.
- 41:44Brad Kearns: So whether or not you're interested in family planning and what's happening in the immediate future, our primary biological drive to exist is to reproduce.
- 41:55Brad Kearns: So when one loses reproductive fitness, this is an extreme indicator that one's stress mechanisms and lifestyle are out of balance.
- 42:04Brad Kearns: And the elite female athletes deal with that routinely, especially in the sports that demand low body fat.
- 42:10Brad Kearns: So if you see a female with six pack.
- 42:12Brad Kearns: She is treading on thin ice, even though she looks great and is getting a lot of followers on her social media posts.
- 42:18Brad Kearns: Um, the body does not really want to be pushed that hard and you have to make all these concessions for general health.
- 42:26Brad Kearns: Yeah, and one thing I mentioned uh, you know I was.
- 42:29Brad Kearns: I was pro circuit for nine years, so I traveled around the world.
- 42:32Brad Kearns: I trained all day.
- 42:33Brad Kearns: I slept for half of my life during my career as a pro triathlete 12 hours, 10 hours a night and two hour every afternoon.
- 42:41Brad Kearns: But I also experienced all around five or six colds every year and it was just part of life as a pro triathlete, with all that traveling and all that training.
- 42:53Brad Kearns: So, hey, that's nine years times, let's say six.
- 42:58Brad Kearns: I had 50 upper respiratory minor infections in my peak years of ages 20 to 30.
- 43:04Brad Kearns: Kind of ridiculous, when you think about it, that I was bashing my immune system and suppressing it so routinely with all that stress, hormone production.
- 43:11Brad Kearns: And, on a less extreme example, that's what the recreational enthusiast is dealing with, because they have little kids that they have to get up and deal with school and then they have to go to work and be responsible and rake the leaves and they want to run eight miles in the morning and it's too much.
- 43:26Brad Kearns: In contrast, that sprint workout that I described fills you with energy and enthusiasm and a level uh appetite and satiety hormone, uh status, so that you go through life eating healthy, nutritious meals and feeling great and having more energy because you work out and train rather than less hey, just wanted to give a shout out to philip.
- 43:49Jerry: I personally worked with philip for about eight months and I lost a total of 33 pounds of scale weight and about five inches off my waist.
- 43:57Jerry: Two things I really enjoy about working with Philip is number one.
- 44:01Jerry: He's really taken the time to develop a deep expertise in nutrition and also resistance training, so he has that depth.
- 44:09Jerry: If you want to go deep on the lies with Philip, but if also if you want to just kind of get some instruction and more practical advice and a plan on what you need to do, you can pull back and communicate at that level.
- 44:21Jerry: Also, he is a lifter himself, so he's very familiar with the performance and body composition goals that most lifters have.
- 44:29Jerry: And also Philip is trained in engineering, so he has some very efficient systems set up to make the coaching experience very easy and very efficient and you can really track your results and you will have real data when you're done working with Philip and also have access to some tools likely that you can continue to use.
- 44:48Jerry: If all that sounds interesting to you.
- 44:51Jerry: Philip, like all good coaches, has a ton of free information out there and really encourage you to see if he may be able to help you out.
- 44:57Jerry: So thanks again, philip.
- 45:00Philip Pape: Yeah, again, the parallel with lifting is I was thinking the exact same thing when you talked about running.
- 45:04Philip Pape: I used to try to train for half marathon.
- 45:07Philip Pape: I never got there.
- 45:08Philip Pape: That was many years ago.
- 45:09Philip Pape: I hated it, I hated the running.
- 45:11Philip Pape: But yeah, you felt like, well, I just did this thing and now I'm exhausted and the rest of the day is done and maybe I'm going to eat more too.
- 45:17Philip Pape: But lifting and sprinting give you a different feeling, especially with the cortisol.
- 45:23Philip Pape: It helps you manage that and feel like you want to be productive, and there's also the mental resilience you get of overcoming these hard things.
- 45:30Philip Pape: The costs of getting lean are very important.
- 45:32Philip Pape: You just mentioned that.
- 45:32Philip Pape: We've talked about that as well, and we've talked to bodybuilders about it who are like, look, it's a serious thing, it's an extreme.
- 45:38Philip Pape: Like any other sport, you have to be willing to do the trade-offs, like the immune system.
- 45:42Philip Pape: People don't think about that.
- 45:43Philip Pape: But if you've already got metabolic adaptation happening during fat loss, now you're just going to exacerbate it with all the other stuff happening.
- 45:50Philip Pape: So all great stuff.
- 45:51Philip Pape: So you mentioned heart health and I think you've talked about something called the Fat Max heart rate.
- 45:57Philip Pape: Do I have that right in my notes and people are thinking again running heart health zone two it's all the rage now getting doing zone training.
- 46:03Philip Pape: What are your thoughts on that?
- 46:06Brad Kearns: Yeah, that's funny because I was just looking down at my notes is the one thing that's really important to cover, and you mentioned it briefly at the outset.
- 46:12Brad Kearns: It's sort of like when can you get permission to run and when can it be beneficial?
- 46:16Brad Kearns: So it's the metabolic and stress impact of one's workout that determines whether it is supportive to long-term fitness improvement as well as longevity, or whether it can set you back.
- 46:28Brad Kearns: And so there's this important concept called fat max heart rate, and it represents the intensity level at which you are burning the maximum number of fat calories per minute, and that goes with the heart rate.
- 46:42Brad Kearns: So fat max heart rate is widely regarded as 180 minus.
- 46:47Brad Kearns: Your age is a great way to pretty accurately estimate your fat max.
- 46:51Brad Kearns: So I'm about to be 60 years old, so I go 180 minus 60.
- 46:55Brad Kearns: My fat max heart rate, my training heart rate at fat max, is 120.
- 47:00Brad Kearns: If I were to speed up and raise my heart rate and go faster, of course I'm gonna be burning more calories the faster I go.
- 47:08Brad Kearns: You burn more calories sprinting than you do when jogging or walking right.
- 47:11Brad Kearns: But at fat max, what happens if you envision a upside down U-shaped curve is you start burning fewer fat calories per minute in favor of a quick spike in glucose burning as well as a quick spike in ventilation and stress, hormone production and everything.
- 47:27Brad Kearns: So this cutoff point is so important to recognize because if you go past fat max, the workout now becomes moderately stressful rather than energizing and restorative.
- 47:39Brad Kearns: So the amount of low intensity movement that one can do there is virtually no ceiling to the benefits you accrue.
- 47:48Brad Kearns: So if I say, philip, hey, let's take this summer, take a break from podcasting and let's hike the 2,000-mile Appalachian Trail in 90 days, that would by and large be a tremendously healthy way to spend the summer.
- 48:02Brad Kearns: We're hiking at a comfortable pace, we're outdoors, we're getting sunlight, we're getting de-stressed from mobile technology and taking breaks and having all kinds of great benefits.
- 48:11Brad Kearns: So there's no upper limit to the benefits of moving more.
- 48:14Brad Kearns: There's research from Cooper Institute about this group called Super Exercisers and they studied these people that reportedly exercise 30 to 35 hours per week for decades.
- 48:25Brad Kearns: I'm envisioning like someone retired who walks five miles every morning and then walks the dog for another 30 minutes at night.
- 48:33Brad Kearns: Whoever these people are that can put in that much exercise, but they're super healthy and they have great longevity.
- 48:38Brad Kearns: Obviously it's not extreme exercise at that level.
- 48:40Brad Kearns: But the active lifestyle is number one.
- 48:42Brad Kearns: Then what happens when you exceed fat max heart rate routinely?
- 48:49Brad Kearns: Then you are getting into these glucose burning workouts that are turning you into a sugar burner and a sugar chomper.
- 48:57Brad Kearns: You are suppressing immune function in favor of this chronic stress hormone production and all the benefits kind of go out the window when you routinely exceed what is regarded as that cutoff between a stressful workout and a restorative workout.
- 49:12Brad Kearns: You mentioned all the fascination with zone two and it's wonderful to see this popularity now because the upper limit of zone two correlates with that fat max heart rate.
- 49:22Brad Kearns: But one contention I have with the fitness movement right now is no one's giving enough love to zone one and the amazing cardiovascular benefits you accrue when you're doing very comfortably paced zone one exercise, like getting out of the car, walking across the parking lot, sending text messages between your sets you're still in zone one and you're still getting all kinds of training effect to the fat burning enzymes and energy systems in the body.
- 49:50Brad Kearns: Here's an important anecdote or a comparison Elouid Kipchoge, the greatest marathon runner of all time, the guy who ran 159 in the marathon and two Olympic gold medals.
- 50:00Brad Kearns: He performs 83% of his weekly mileage in zone one, not zone two.
- 50:08Brad Kearns: Of his weekly mileage in zone one, not zone two, zone one, he does around 9% in zone two and 7% at the higher zones where he's really hitting it hard and doing these amazing track workouts.
- 50:17Brad Kearns: But what he's mostly doing for you and I, the direct comparison would be a medium to brisk walk.
- 50:25Brad Kearns: Now, for him, zone one is eight minute pace per mile at high altitude for an easy 15 mile run.
- 50:31Brad Kearns: Uh, because he's so physically conditioned.
- 50:34Brad Kearns: Yeah, and he's running a marathon, by the way, at a pace of four, 34 per mile.
- 50:39Brad Kearns: So an eight minute mile, even though it's pretty impressive to you and I, is way, way slower 63% slower than his marathon pace.
- 50:46Brad Kearns: Wait a second.
- 50:47Brad Kearns: Take the average marathoner and slow down 63%.
- 50:51Brad Kearns: Guess what you're doing?
- 50:51Brad Kearns: You're walking and you're training, just like the greatest runner of all time trains.
- 50:57Brad Kearns: There's the argument to emphasize walking and not worrying about having to shuffle down with this breaking stride because you're not adapted to run correctly anyway.
- 51:08Philip Pape: Yeah, I love it.
- 51:09Philip Pape: Two things come to mind there, brad.
- 51:11Philip Pape: One is recent research that confirmed again that the volume of movement, no matter the intensity, is pretty much equally effective for heart health.
- 51:21Philip Pape: Right, which is what you're kind of saying.
- 51:22Philip Pape: Like, you can walk, walk, walk, walk a ton and it's cool, like, and it's great for you.
- 51:26Philip Pape: It also makes me think about the mode of movement and training.
- 51:33Philip Pape: We've been talking about combining walking with lifting and sprinting.
- 51:34Philip Pape: When you lift for 90 minutes like that's typical for me, a 90 minute session and I look at my Apple watch there are moments that I peak into zone two on a heavy deadlift or on, you know if the rest period short or whatever, so you're going to hit zone two and then sprinting, you're going to hit it, of course, maybe even zone three or four, because that's very short, yeah, whatever Zone five.
- 51:52Philip Pape: Zone five, and the percentages you mentioned actually align perfectly with that idea.
- 51:56Philip Pape: Not that you have to measure it I don't even care about it, to be honest, and personally I don't know if you do but I just Not at all.
- 52:03Brad Kearns: No, I mean, the reason you need to care about heart rate is if you're at risk of getting into these chronic patterns.
- 52:08Brad Kearns: So when I was a pro triathlete, I obsessively measured my heart rate at every single workout, making sure that that beeper alarm did not go off, because that is the destruction of a desired effect of the training session and I could not get away with that stuff.
- 52:23Brad Kearns: And, interestingly, because I was so fit back when I was a young person and racing fast, I would do a lot of my workouts in zone one, just like Kipchoge, because zone two was six minute pace per mile and you can't pound the body with that kind of impact, even though it feels comfortable.
- 52:39Brad Kearns: And I'm still chit chatting with my training partner the training becomes too stressful and so the fitter you get, the more time you're spending building that aerobic base correctly.
- 52:49Brad Kearns: But again, we have to realize that the stress is relative, such that our protocol for preparing for our modest endurance goals would be a lot of walking and then an occasional effort where you push your body hard and you have a great effort doing the weekend 10k race or whatever it is, whatever your goals are.
- 53:09Brad Kearns: So I don't want to blanketly trash running.
- 53:12Brad Kearns: It's been a part of my life forever and I've got a lot of great benefits out of it.
- 53:16Brad Kearns: I have buddies from high school that are still running and enjoying it because they've been fit their whole life and the run is like a brisk walk for most people, but we have to honor that.
- 53:26Brad Kearns: Fat max heart rate is like a brisk walk for most people, but we have to honor that fat max heart rate.
- 53:31Brad Kearns: See what that represents for us in our own workout protocol and accordingly proceed at that pace rather than bullheadedly and doggedly assume a running pace because you think that you have to.
- 53:42Brad Kearns: And also what this means is the duration of the workout has to be at, or below fat max heart rate.
- 53:47Brad Kearns: So what this means is the duration of the workout has to be at, or below fat max heart rate.
- 53:49Brad Kearns: Right?
- 53:49Brad Kearns: So as we get tired as the workout proceeds, we have to slow down, and so you might be able to run one or two miles jogging before that heart watch beeps and then it's going to start beeping the rest of the workout.
- 54:00Philip Pape: Fair point, because the fixed point is that heart rate, which then shifts as you get fatigued.
- 54:05Brad Kearns: Yeah, and what a lot of people do is they say, hey, let's go and keep a nine minute per mile pace for our six mile run.
- 54:11Brad Kearns: Well, that doesn't make any sense to the body and the brain.
- 54:15Brad Kearns: The brain knows intensity and the heart knows intensity.
- 54:18Brad Kearns: So your nine minute pace should be nine nine, nine, 20, nine, 45, 10, 10, 15, whatever, because we're honoring heart rate, not blindly adhering to some pace.
- 54:30Brad Kearns: The only time that you should do that is in a race where you're trying to run your best time.
- 54:34Brad Kearns: Of course you want to run the same split per mile.
- 54:36Brad Kearns: That's how records are set and personal records are set, but training is entirely different than race model for most people two more things I want to cover before I do.
- 54:46Philip Pape: I wanted to say a nerdy thing.
- 54:47Philip Pape: When you mentioned the fat max heart rate and you said you know, it's in the shape of and I thought you were going to say parabola, because I'm a math guy and you said upside down you, which is what most people would get.
- 54:56Brad Kearns: You're a good communicator, but like, I think, parabola, that's the word I was looking for.
- 55:00Brad Kearns: Oh, okay, okay.
- 55:02Philip Pape: But it's okay.
- 55:03Philip Pape: You probably don't want to use it in most contexts, as people are like what are you talking about?
- 55:06Philip Pape: Um, I was thinking of price optimization from economics, where you have like price economics major.
- 55:13Brad Kearns: So now I'm with you, man.
- 55:14Brad Kearns: I remember that, the price optimization curve.
- 55:17Brad Kearns: Yeah, I had a instructor with a british accent.
- 55:19Brad Kearns: Let's, let's, investigate our price optimization curve.
- 55:22Brad Kearns: Oh, you can't charge too much and make more money.
- 55:26Brad Kearns: I see, I see.
- 55:28Philip Pape: Unless you want to preserve your monopoly.
- 55:29Philip Pape: It's Microsoft new back when they sold Windows 98.
- 55:32Philip Pape: They sold it way cheaper than the price.
- 55:34Philip Pape: Max profit maximization to keep the market, you know.
- 55:37Brad Kearns: Wow.
- 55:37Philip Pape: Anyway.
- 55:37Philip Pape: So two final things.
- 55:39Philip Pape: That one is let's talk about people who do love running or maybe are good at it or want to get good at it and still want to do it, and they're like I hear you, brad, but I still want to run.
- 55:52Philip Pape: How do I do it?
- 55:52Philip Pape: And then we can conclude with how do people incorporate walking?
- 55:53Philip Pape: I think those are two good places to kind of end the.
- 55:55Brad Kearns: Nice.
- 55:55Brad Kearns: So you want permission to run?
- 55:57Brad Kearns: That's great.
- 55:57Brad Kearns: Let's first look at the propensity for an addictive approach.
- 56:01Brad Kearns: And we have a whole chapter in the book called the Ordeal of the Obligate Runner.
- 56:06Brad Kearns: And the very definition of addiction is requiring a hit or a dose in order to feel normal.
- 56:13Brad Kearns: So we think about the addicts on the street.
- 56:17Brad Kearns: They're drug addicts and they need it.
- 56:18Brad Kearns: They steal money and they want to go get high.
- 56:20Brad Kearns: Well, it's not really that they want to get high, that might have been at the start.
- 56:23Brad Kearns: They need to steal money and go get their drug to feel normal, to get to baseline.
- 56:30Brad Kearns: So if you're listening and you're wondering, am I an addict to exercise?
- 56:33Brad Kearns: If you feel cranky, irritable and out of sorts, if you miss your workout on a particular day, this is a sign of addiction or an unhealthy obsession with exercise.
- 56:45Brad Kearns: And that's very easy to drift in that direction, especially as your goals become more refined and sophisticated, as in you get more and more immersed into endurance culture or gym culture or CrossFit culture.
- 56:58Brad Kearns: So we have to be very careful and realize like and I had to learn this as a high performing athlete to like hey, look in the mirror and what are my goals?
- 57:06Brad Kearns: My goals are to excel in the races.
- 57:06Brad Kearns: And what are my goals?
- 57:07Brad Kearns: My goals are to excel in the races and I'm making a living at this, so it's very important.
- 57:12Brad Kearns: It's not just a hobby.
- 57:13Brad Kearns: So I need to take absolute best care of my body.
- 57:16Brad Kearns: So I had built in guardrails against overtraining, because if I disperse that energy in the workout, it was costing me a chance at winning prize money in the race.
- 57:26Brad Kearns: So you very quickly become a really, really smart trainer when you get your ass kicked in the race because you came in a little bit tired.
- 57:34Brad Kearns: So those are nice protocols to have and I'm just honoring that and sharing that with other people that like look, if you're here to do a favor for your health, to promote longevity, to prevent disease and to get the body composition of your dreams, these are all warranting a sensible approach rather than an overly stressful approach.
- 57:56Brad Kearns: So that permission to run let's really ask what you're all about.
- 57:59Brad Kearns: And if you want to really enjoy yourself and take care of yourself, you can slow down and it's okay and you're still getting a good workout.
- 58:05Brad Kearns: But that permission comes from how well you perform at fat max heart rate.
- 58:10Brad Kearns: Now here's another little side note.
- 58:12Brad Kearns: If you're not, if you're frustrated that you have to go so slow, you're allowed to do jog walks for the duration of your workout.
- 58:19Brad Kearns: So you can go and jog for 30 seconds and then walk it off just as your heart rate's about to climb and start beeping and ruining the intended metabolic effects of the workout.
- 58:30Brad Kearns: You walk for a minute or two or three or four minutes and then do another jog and then walk and then do another jog, so you get some running in.
- 58:37Brad Kearns: You get that sensation of running.
- 58:39Brad Kearns: That's great.
- 58:41Brad Kearns: The other side of the coin that you asked was how do we get a more walking-oriented lifestyle?
- 58:47Brad Kearns: I think we have to make a fundamental shift in our mindset and our philosophy to put walking in a different category.
- 58:56Brad Kearns: It's not like a fitness option, it's really like sleep.
- 59:00Brad Kearns: It's a human genetic expectation for health and when we don't move sufficiently during everyday life, we incur all manner of immediate consequences.
- 59:10Brad Kearns: One of them is a decline in cognitive function the brain research.
- 59:14Brad Kearns: There's one study from Stanford that I mentioned in the book you experience cognitive decline after 20 minutes of focusing on an intense, peak performance cognitive task.
- 59:23Brad Kearns: So if you do not take a break every 20 minutes from intense work, a break will be taken for you, and I find, with my tabs open on my browser, I have these high jump videos that I love watching, and I find myself watching them instead of focusing on a book manuscript or a podcast outline because I've been working for too long.
- 59:42Brad Kearns: Afternoon nap, which I'm a huge fan of, because I know when I come back I'm going to be kicking butt at a different level than if I were just powering through all these natural declines in cognitive function.
- 59:54Brad Kearns: So that's a big vote there for just sprinkling in short and longer walks throughout the day as a fundamental necessity to be at your best anyway.
- 1:00:06Philip Pape: You're a master at reframing this stuff.
- 1:00:08Philip Pape: I really love this.
- 1:00:09Philip Pape: I'm glad you came on to talk about this because just the way I mean think of walking as sleep Beautiful right Because people are thinking they have to almost force themselves, or it's their training or whatever, and I haven't tried to talk about it in language like walking should just naturally flow from the things you enjoy doing and let's find a way to incorporate into your life anyway.
- 1:00:30Brad Kearns: Yeah.
- 1:00:30Philip Pape: And not think of it as trying to get steps right, Like people just think of it as trying to get steps, even though it's a good way to measure a proxy.
- 1:00:36Brad Kearns: If that works for you, that's great.
- 1:00:38Brad Kearns: You know if some accountability is fine.
- 1:00:40Brad Kearns: My other favorite example is like having a dog.
- 1:00:44Brad Kearns: I'm a big dog lover.
- 1:00:45Brad Kearns: My dog of 15 years is gone now.
- 1:00:47Brad Kearns: She had a great run but like I didn't think for a second that I wasn't motivated enough or I was too busy to get that dog out twice a day like she deserved.
- 1:00:57Brad Kearns: It's like if you're going to adopt an animal, you have a commitment, a lifelong commitment, to give the animal the life it deserves.
- 1:01:03Brad Kearns: So I don't care if it's snowing or too hot or you're too busy.
- 1:01:06Brad Kearns: You get the dog out for their daily exercise and to serve something higher than yourself and your own fickle forces of like motivation and willpower.
- 1:01:15Brad Kearns: Like you mentioned at the start of the show, that's a no brainer.
- 1:01:18Brad Kearns: So I think the dog is in your corner.
- 1:01:20Brad Kearns: And how can you turn down?
- 1:01:21Brad Kearns: I mean, look the dog in the eye and say sorry, I'm too busy, I got a work deadline.
- 1:01:25Brad Kearns: I can't take you out for five minutes, boy, that'd be tough.
- 1:01:32Brad Kearns: I can never turn my dog's face down.
- 1:01:33Brad Kearns: And then the dog has that amazing circadian programming where, at 5.07, they know it's time to eat and they're like where's my bowl?
- 1:01:37Brad Kearns: It's after five, you're late.
- 1:01:39Brad Kearns: Oh, I love it, man.
- 1:01:40Philip Pape: Yeah, yeah.
- 1:01:41Philip Pape: We have two little dogs, and one is really good at hopping up on you.
- 1:01:44Philip Pape: She's so little she hops like a foot up under your calf Like it's time to go out, Even if you took her out an hour before.
- 1:01:50Philip Pape: If it's the time, it's time, like it doesn't matter.
- 1:01:54Philip Pape: Oh man, this has been fantastic.
- 1:01:56Philip Pape: So many amazing things here about not only why to do this, but just you know the sprinting and the lifting and the walking and what it means to be a human doing hard things but also doing things that are fulfilling for our lives.
- 1:02:08Philip Pape: Being kind of an athlete of aging is the term I've heard some people use.
- 1:02:12Philip Pape: Is there anything we didn't cover that you think is worthwhile, that you wanted to bring up.
- 1:02:17Brad Kearns: Well, I'm glad we got into sprinting because that's been my obsession of recent years and I think it just feels so good to kind of see yourself as an actual performing athlete, where I think in endurance scene we're just shufflers, heading down the sidewalk and accumulating miles and we're so far from you know, an actual athletic competition type of mentality and even if it's not a big part of your life, I promote, you know, with my whole message and you land on my website and it says pursue peak performance with passion throughout life.
- 1:02:50Brad Kearns: I think we need something to give us an edge and give us a little bit of nervousness and, you know, trepidation that we're putting ourselves out there and we're still competing at something and pursuing goals throughout life.
- 1:03:04Brad Kearns: Because what instead we see in culture are dudes watching the NFL for seven hours every weekend and perhaps offering up some stories about how, back in the day, you know, I was supposed to play quarterback for SC but I banged up my shoulder at the summer practice and that was the end of my career.
- 1:03:20Brad Kearns: Yeah, yeah, yeah, whatever, everyone's got a story and they have their heyday back in their youth and then the rest of the time we just sit around and watch others.
- 1:03:27Brad Kearns: I think there's a better way to go through life and to pick something that's scary and challenging, that you have to train for and prepare for, and that will get you out the door.
- 1:03:37Brad Kearns: When things are, you know, have a tendency to get comfortable and convenient.
- 1:03:41Philip Pape: So be an athlete, not a shuffler find an edge compete.
- 1:03:45Philip Pape: Pursue your goal always be improving, always be improving.
- 1:03:48Philip Pape: Pick something scary, pick something challenging.
- 1:03:49Philip Pape: Totally on board with that philosophy, my friend.
- 1:03:57Brad Kearns: And where do you want folks to look you up?
- 1:03:58Brad Kearns: Well, we talked about Born to Walk and we have a great website called borntowalkbookcom where we have these bonus items.
- 1:04:03Brad Kearns: When you place an order at whatever retailer you like, you come back and you can get these great PDF download resources and shopping discounts and all kinds of things.

- 1:04:13Brad Kearns: I would love to have you on someday.
- 1:04:15Brad Kearns: We can talk more about strength training and that precise approach that you communicate, so maybe that'll be a good place for people to start and bradkearnscom all kinds of fun stuff going on and I'm so glad to connect with you here and great interview.
- 1:04:29Brad Kearns: Keep up doing the great work that you're doing.

- 1:04:39Philip Pape: So thank you for the offer and this is a pleasure.
- 1:04:41Philip Pape: I could talk to you for hours and, honestly, there are other topics like sprinting we could get into in the future, I'm sure.
- 1:04:46Brad Kearns: So thanks again for coming on Brad.
- 1:04:47Brad Kearns: Thanks a lot, Philip.
