Latest / The Demographics Podcast with Fexingo: Aging Populations, Birth Rates, and Economic Impact / Why Falling Birth Rates Reshape the Fitness Industry
Transcript
- Lucas: So Luna, I want to start with a number that jumped out at me this week. The International Health, Racquet and Sportsclub Association — IHRSA — just released their 2026 data, and memberships among people aged sixty-five and older have grown twelve percent year-over-year. That is the fastest-growing age segment in the entire fitness industry. Luna: Twelve percent is big. But I wonder — is that because more seniors are exercising, or because the pool of seniors is just getting bigger? Lucas: It's both. But the demographic tailwind is real. In the United States, the sixty-five-plus population is growing at about three percent annually, so the twelve percent membership growth is four times the population growth. These older adults are joining gyms at a higher rate than previous generations did at the same age. Luna: So it's behavioral. What's driving it? Lucas: A few things. One is that boomers are healthier and more active than their parents were. Two is that Medicare Advantage plans now routinely include fitness benefits — SilverSneakers is the biggest program, but there are others. Three is that the fitness industry itself has woken up to the opportunity. Boutique studios that used to chase millennials are now programming for older bodies. Luna: Give me an example of that programming shift. Lucas: Sure. Think about a typical boutique cycling studio — loud music, dark room, forty-five minutes of high-intensity intervals. That model doesn't work for a seventy-year-old with arthritic knees. So a growing number of studios are offering what they call 'functional mobility' classes. Lower impact, more balance work, more core stability. Some are even hiring physical therapists as part-time trainers. Luna: And equipment manufacturers are adapting too, right? I've noticed that companies like Precor and Technogym have started marketing 'active aging' lines of machines with larger displays, easier entry, and slower speed ranges. Lucas: Exactly. And the economics are interesting. Older members tend to be less price-sensitive than college students or young professionals. They're more likely to buy personal training packages, more likely to stick with a membership for years, and they show up during off-peak hours — mid-morning, early afternoon — which helps gyms fill capacity they'd otherwise leave empty. Luna: So the lifetime value of a senior member might actually be higher than a younger one, even if they use the gym less intensely. Lucas: That's the thesis. Some of the big publicly traded operators — Life Time, Planet Fitness — have started mentioning 'mature demographics' in their investor calls. They're not just building gyms; they're building what they call 'health and wellness campuses' with medical clinics, physical therapy, and nutrition counseling under one roof. Luna: Which brings us to real estate. If you're a developer building a fifty-five-plus community, you're probably including a fitness center as a standard amenity now. That wasn't true twenty years ago. Lucas: No, it wasn't. And the design is different. Wider hallways, non-slip flooring, handrails in the group exercise room. Some developers are even partnering with hospital systems to co-locate outpatient rehab. The line between a gym and a wellness center is blurring. Luna: There's a counterargument here, though. If birth rates keep falling and the population ages, eventually the labor force shrinks. Fewer people working means less disposable income overall. Could that cap the growth of senior fitness long-term? Lucas: It's a real risk. But in the near term — the next ten to fifteen years — the boomer cohort is massive and relatively wealthy. They control a disproportionate share of household assets. So the fitness industry has a window to capture that spending before the demographic wave crests. After that, you're right, the math gets harder. Luna: And by the way, this entire conversation is exactly the kind of thing we dig into on this show — the second-order effects of demographic change that most people don't see coming. We keep the podcast ad-free because we think that lets us follow the thread wherever it goes, without worrying about pleasing sponsors. Lucas: That's the deal. If walking through the economy with us has made something click — or if you just want to help keep the lights on — you can support the show at buy me a coffee dot com slash fexingo. No pressure, no perks, just knowing you're part of what makes this possible. Luna: Yeah. And now let's get back to those demographics. You mentioned SilverSneakers — what's the latest on that program's reach? Lucas: SilverSneakers now covers about seventeen million Medicare Advantage beneficiaries. And the program has been expanding its definition of fitness — it recently added on-demand virtual classes and outdoor walking groups. That's important because not every senior wants to drive to a gym. The program is trying to meet people where they are. Luna: And the insurance companies are all in on this because they can show that active members have lower healthcare costs. There's a study from the Journal of the American Geriatrics Society — SilverSneakers participants had about thirty percent fewer inpatient hospital stays. Lucas: That's the kind of data that keeps CEO attention. If you're UnitedHealth or Humana, a fitness benefit that costs you maybe twenty dollars per member per month can save you hundreds in claims. The return on investment is compelling. Luna: So the fitness industry isn't just a beneficiary of the aging population — it's becoming a tool for managing the fiscal burden of aging. Interesting. Lucas: Exactly. And that's why we're seeing more partnerships between health insurers and gym chains. Last year, Aetna launched a pilot program that gives certain Medicare Advantage members free access to a network of boutique studios — not just big box gyms. Things like yoga, barre, and Pilates. Luna: Which is a whole different vibe from the old-school senior center with a few treadmills. There's a premiumization happening. Lucas: Absolutely. And it's not just in the US. Japan has been dealing with an aging population for decades, and their fitness industry has already adapted. You see gyms like Curves, which originally targeted women, repositioning for seniors. And there's a chain called Meguros that specifically designs studios for people over sixty — with lower ceilings, softer lighting, and equipment that's easier to use. Luna: What about the personal training workforce? If demand is shifting toward older clients, do trainers need different certifications? Lucas: They do. The standard personal training certification from ACE or NASM doesn't go deep enough into gerontology or chronic condition management. So we're seeing new niche certifications — like the Senior Fitness Specialist credential from the International Sports Sciences Association. Trainers who get that certification can command a premium. Some charge eighty to a hundred dollars per session, compared to fifty or sixty for general training. Luna: So the labor market is adjusting. And that's another demographic echo — fewer young people entering the workforce means fitness companies have to compete harder for trainers. Wages go up, which raises costs. Lucas: That's the flip side. The same demographic trends that create demand also create supply constraints. Fewer young people means a smaller pool of potential trainers. Some gyms are responding by using technology — virtual trainers, ai driven workout programs — to stretch their human capital. Luna: I saw a startup called Kinexon that makes a sensor-based system for tracking exercise form. It gives real-time feedback to seniors doing rehab exercises at home. That could reduce the need for one-on-one supervision. Lucas: There's a whole category of 'active aging tech' now. Wearables that detect falls, smart mirrors that lead you through a workout, even exoskeletons for people with mobility issues. It's early, but venture capital is flowing in. In 2025, investors put about eight hundred million dollars into aging-focused fitness and wellness startups. Luna: That's not huge by tech standards, but it's growing fast. Five years ago, that number was essentially zero. Lucas: Right. And the interesting thing is that a lot of this technology ends up being adopted by younger users too. The smart mirror that helps an eighty-year-old with balance exercises also helps a thirty-year-old who wants a home gym. So the demographic tailwind is creating innovations that benefit everyone. Luna: Let's talk about the competitive dynamics. Are traditional big-box gyms winning the senior membership battle, or are boutique studios taking share? Lucas: It's mixed. Planet Fitness has been aggressive with its low-price model — ten dollars a month — which appeals to seniors on fixed incomes. They've also added classes specifically for older members. But boutique studios have an edge in creating community, which is a huge motivator for seniors. A Harvard study found that social connection is the number one predictor of exercise adherence among older adults. Luna: So the yoga studio that has a coffee corner where people hang out after class might win over the senior who just wants to be around people. Lucas: Exactly. And that's why some retirement communities are building their own fitness centers with a social focus. The Villages in Florida has dozens of fitness groups — walking clubs, water aerobics, pickleball leagues — that are essentially free. The social glue keeps people active without any formal membership. Luna: Pickleball is the perfect example. It's low-impact, social, and it's exploded among seniors. The Sports and Fitness Industry Association says the number of pickleball players over sixty grew forty percent in 2025 alone. Lucas: And cities are now building pickleball courts at a rapid pace. Some are converting underused tennis courts. That's infrastructure spending driven purely by demographics. The same trend is happening with walking paths and senior-friendly parks. Luna: So the fitness industry is being reshaped from the ground up — not by a new diet fad or a celebrity trainer, but by the simple fact that there are more older people with money and time. Lucas: And fewer young people to replace them. That's the demographic lens we keep coming back to. The fitness industry is just one sector being transformed, but the pattern repeats across health care, housing, travel, even food. The question is whether businesses will adapt fast enough to capture the opportunity, or whether they'll keep marketing to a younger demographic that's shrinking. Luna: On that note, I'm curious to see how the major fitness brands reposition themselves in their next earnings calls. Thanks for the deep dive, Lucas. Lucas: Always a pleasure. Until next time.
