THE BENEFITS OF STRENGTH TRAINING · Your Daily Dose

• 0:00
  Speaker 1: Sometimes things are really obvious. Here we are on September 15th,
• 0:04
  Speaker 1: halfway through the month of September. No hurricanes yet here
• 0:08
  Speaker 1: in Florida. Thank God. We're going to talk about today
• 0:13
  Speaker 1: what happens to your body when you do some strength
• 0:15
  Speaker 1: training regularly. I think we all know, but a new
• 0:19
  Speaker 1: article says, even though you can lose up to 50%
• 0:22
  Speaker 1: of your muscle mass by age 80, but you can
• 0:25
  Speaker 1: reverse it. So let's see what it has to say.
• 0:27
  Speaker 1: Stay tuned. Hi and welcome to Health Talk with Dr. Len,
• 0:31
  Speaker 1: your daily dose. The information you hear on this show
• 0:34
  Speaker 1: is informational. It's not meant to diagnose or treat any disease.
• 0:38
  Speaker 1: Any kind of complete health conditions must be checked out
• 0:42
  Speaker 1: and discussed with your primary care physician. Get ready for
• 0:46
  Speaker 1: the good news of the day. God bless you folks.
• 0:50
  Speaker 1: And here is Dr.
• 0:51
  Speaker 2: Len.
• 0:52
  Speaker 1: Our daily devotional today comes from the book of John
• 0:54
  Speaker 1: chapter 15. Rest in me my child. This time devoted
• 0:59
  Speaker 1: to me is meant to be peaceful, not stressful. You
• 1:02
  Speaker 1: don't have to perform in order to receive my love.
• 1:05
  Speaker 1: I have boundless, unconditional love for you. How it grieves
• 1:09
  Speaker 1: me to see my children working for love, trying harder
• 1:12
  Speaker 1: and harder, yet never feeling good enough to be loved.
• 1:16
  Speaker 1: Be careful that your devotion to me does not become
• 1:18
  Speaker 1: another form of work. I want you to come into
• 1:21
  Speaker 1: my presence joyfully and confidently. You have nothing to fear.
• 1:26
  Speaker 1: for you wear my own righteousness. Gaze into my eyes,
• 1:30
  Speaker 1: and you will see no condemnation, only love and delight
• 1:33
  Speaker 1: in the one I see. Be blessed as my face
• 1:37
  Speaker 1: shines radiantly upon you, giving you peace. Stay tuned.
• 1:55
  Speaker 2: So so 727-916-4215 to reach me off air. As people
• 2:42
  Speaker 2: get older and become less active, their bodies change in
• 2:48
  Speaker 2: subtle but significant ways.
• 3:08
  Speaker 1: Muscle mass declines, metabolism slows, and gaining body fat becomes easier.
• 3:12
  Speaker 1: By age 80, people may have lost as much as
• 3:15
  Speaker 1: 30-50% of their skeletal muscle mass and function. However, strength
• 3:20
  Speaker 1: training can dramatically slow this decline and improve body composition.
• 3:25
  Speaker 1: Strength training, also known as resistance training, is a form
• 3:28
  Speaker 1: of exercise that builds muscle strength and lean mass by
• 3:31
  Speaker 1: working against resistance from dumbbells, bands, or your own body weight.
• 3:36
  Speaker 1: It just doesn't tire the muscles off, but sets off
• 3:38
  Speaker 1: a chain reaction across your nervous, muscular, energy, and hormonal systems.
• 3:43
  Speaker 1: Margarita Cervanea, a San Diego fitness coach specializing in strength training,
• 3:49
  Speaker 1: said understanding that chain reaction explains why strength gains happen
• 3:53
  Speaker 1: quickly at first and why muscle growth takes longer. It
• 3:56
  Speaker 1: all starts with the nervous system. When you decide to
• 4:00
  Speaker 1: lift something, your brain sends signals to the muscles while
• 4:03
  Speaker 1: your nervous system simultaneously receives information about movement from your muscles, joints,
• 4:08
  Speaker 1: and tendons. The more force you need to produce, the
• 4:11
  Speaker 1: more motor units, each made up of a nerve cell
• 4:13
  Speaker 1: and a muscle fiber it controls, your nervous system can
• 4:16
  Speaker 1: call into action. These neural adaptations help explain why you
• 4:21
  Speaker 1: become noticeably stronger in the first few weeks of strength training.
• 4:25
  Speaker 1: Upon receiving a nerve signal, muscle fibers contract and use
• 4:29
  Speaker 1: adenosine triphosphate, ATP, for energy. Short, intense, sets, rely more
• 4:35
  Speaker 1: heavily on anaerobic pathways, but aerobic metabolism never fully shuts off.
• 4:41
  Speaker 1: All systems stay active at once, just in different proportions.
• 4:45
  Speaker 1: Muscle cells sense tension and translate it into biochemical signals
• 4:49
  Speaker 1: to trigger protein synthesis. At the same time, your sympathetic
• 4:53
  Speaker 1: nervous system activates, heart rate and breathing quicken, blood is
• 4:57
  Speaker 1: redirected toward murky muscles and stored energy in the form
• 5:00
  Speaker 1: of glycogen or extra glucose, and fat is mobilized. A
• 5:05
  Speaker 1: cascade of hormones, including adrenaline, norepinephrine, cortisol, insulin, and testosterone,
• 5:10
  Speaker 1: and your growth hormones become involved. The real growth happens
• 5:15
  Speaker 1: after you leave the gym. While exercise stimulates muscle protein synthesis,
• 5:20
  Speaker 1: the recovery period is when the body restores energy balance
• 5:23
  Speaker 1: and repairs and remodels muscle tissue. Micro-damage can happen after
• 5:28
  Speaker 1: an unfamiliar or unusually hard session, but more damage doesn't
• 5:32
  Speaker 1: mean more gains. Severe damage just extends recovery time without
• 5:36
  Speaker 1: improving results. When adequate protein, energy intake, sleep, and recovery
• 5:41
  Speaker 1: are available, your muscle size and strength increase over weeks
• 5:44
  Speaker 1: and months. Compared with strength training, cardiovascular training develops your
• 5:49
  Speaker 1: heart and lungs' ability to supply oxygen during sustained effort.
• 5:53
  Speaker 1: Bodybuilding uses strength training as its primary tool, paired with
• 5:57
  Speaker 1: structured nutrition plans built around distinct phases, gaining muscle, maintaining physique,
• 6:03
  Speaker 1: and cutting out fat. So what are the benefits of
• 6:05
  Speaker 1: strength training? Number one, stronger muscles. 2025 meta-analysis found that
• 6:11
  Speaker 1: strength training significantly improves muscle strength. Number two, longer life.
• 6:18
  Speaker 1: Regular strength training has been associated with a lower mortality risk.
• 6:21
  Speaker 1: A June study found that adults who did 90 minutes
• 6:24
  Speaker 1: of strength training per week had a 13% lower risk
• 6:27
  Speaker 1: of death from any cause. healthy body composition and metabolisms.
• 6:32
  Speaker 1: Number three, strength training improves your muscle-to-fat ratio by building
• 6:36
  Speaker 1: or preserving lean mass. Number four, stronger bones. Every time
• 6:41
  Speaker 1: your muscles pull against your bones during resistance training, that
• 6:45
  Speaker 1: mechanical stress stimulates bone-forming processes and promotes adaptations that can
• 6:51
  Speaker 1: maintain or increase bone mineral density. Number five, chronic disease
• 6:56
  Speaker 1: risk reduction. Regular strength training may help prevent They manage
• 7:00
  Speaker 1: several major chronic conditions, including type 2 diabetes, cardiovascular disease, obesity,
• 7:07
  Speaker 1: chronic lower back pain, arthritis. Number six, better mental health
• 7:12
  Speaker 1: and sleep. The mind-body connection here runs deeper than exercise
• 7:17
  Speaker 1: improves mood. Resisting training may influence brain function directly, including
• 7:21
  Speaker 1: neurochemical signaling and levels of brain-derived neurotrophic factor, a protein
• 7:26
  Speaker 1: that supports growth and the health of neural connections. What
• 7:31
  Speaker 1: are the core strength training exercises? Okay, start with squat movements,
• 7:37
  Speaker 1: hinge movements, push exercises, pull movements, carry exercises. Farmer carries
• 7:45
  Speaker 1: improve grip strength, core stability, overall function strength. Core and
• 7:49
  Speaker 1: bracing exercises, planks and loaded carries strengthen the abdominals. Push exercises,
• 7:55
  Speaker 1: bench press, overhead press, push-ups, hinge movements, deadlifts, hip thrusts,
• 8:01
  Speaker 1: squat movements, squats and lunges. Keep these tips in mind
• 8:05
  Speaker 1: to train safely and get the most out of your workout.
• 8:07
  Speaker 1: Prioritize technique over weight. Increase weight repetitions and set gradually
• 8:12
  Speaker 1: as exercise gets easier. Finish each session with a cool
• 8:15
  Speaker 1: down that includes light activity and gentle static stretching. Give
• 8:19
  Speaker 1: a muscle group at least one full rest day before
• 8:22
  Speaker 1: training it again. Stop if you feel sharp pain which
• 8:25
  Speaker 1: is different from normal muscle fatigue. What are the risks?
• 8:31
  Speaker 1: muscle soreness, pain, tendinopathy. What should you eat during strength training?
• 8:37
  Speaker 1: First and foremost, your diet should align with your goals
• 8:39
  Speaker 1: and intensity of your physical activity. Protein provides the building
• 8:43
  Speaker 1: blocks needed to repair and maintain muscle. Carbohydrates are equally
• 8:47
  Speaker 1: important because they replenish muscle glycogen stores. Macronutrients may vary
• 8:52
  Speaker 1: by body size, energy intake, and training volume and goals.
• 8:56
  Speaker 1: Most people exercising can meet their protein needs with approximately 1.4
• 9:00
  Speaker 1: to 2 grams per kilogram of body weight. According to her,
• 9:06
  Speaker 1: creatine has one of the strongest evidence bases among supplements
• 9:10
  Speaker 1: used in strength training. It helps muscles rapidly regenerate energy
• 9:13
  Speaker 1: during short, high-intensity efforts and can support improvements in strength
• 9:18
  Speaker 1: and training performance. And again, not creatine monohydrate, the magnesium
• 9:23
  Speaker 1: form of creatine, which is available at Nutritional Frontiers. Hey, everybody.
