Your gut lining rebuilds itself every five days — faster than any other tissue in your body — and that turnover rate is either your best defense or your biggest vulnerability, depending on what you're doing to it. In the final episode of this series with stem cell scientist and STEMREGEN founder Christian Drapeau, Eric Malzone digs into why the intestinal lining is "the most fragile and vulnerable part of your body," how estrogen withdrawal at menopause quietly wrecks gut repair, and why Christian believes the real story of aging isn't inflammation or free radicals — it's a failure of the body's own repair system. They also get into a jaw-dropping 1940s case study on gut bacteria and psychosis, the specific bacteria linked to autoimmune disease and diabetes, and why Christian thinks "stem cells bring cure" is the hardest sentence in modern medicine.

Key Takeaways

• 🔄 Your gut lining fully renews every 5 days — versus 30 days for skin
• 📏 Unfolded, your intestinal lining covers roughly the surface area of a tennis court, packed into ~10-13 feet of tube
• 🧫 That lining is one cell thick — the only barrier between your bloodstream and everything in your gut
• 🌸 Estrogen withdrawal at menopause reduces stem cell proliferation and strips away its anti-inflammatory protection, weakening gut repair
• 🦠 The "estrobolome" — a distinct, estrogen-linked gut microbiome that shifts dramatically after menopause
• 🧠 A 1940s-50s study fed institutionalized psychosis/seizure patients ~700 billion microorganisms/day via fermented yogurt — many normalized within two weeks
• 💊 Christian's core thesis: failure of endogenous repair, not inflammation or free radicals alone, is the fundamental cause of aging and disease
• 🩺 25 years of research shows that simply increasing circulating stem cells can produce results Christian calls "phenomenal" — including an ongoing Parkinson's study

Paul Lunter didn't start out trying to build a wellness empire — he was in construction, watched someone in pain step in and out of the shower for relief, and built a machine instead. Thirty-seven years later, that machine (HydroMassage) has grown into WellnessSpace Brands: five product lines, 400 million sessions delivered, and installations in 50+ countries at Planet Fitness, Life Time, Gold's Gym, and beyond. Lunter walks Eric Malzone through the company's medical-market origins, the R&D behind machines like the PolarWave Dry Plunge and the company's newest RedZone sauna which uses no wood, and why he thinks recovery is a permanent industry shift rather than another fitness fad.

Key Takeaways

🛠️ Paul Lunter built the first HydroMassage machine in 1989 after watching someone step in and out of the shower for pain relief multiple times a day — before recovery was even a category

🏥 The brand started as "Aquamed" selling into chiropractors, physical therapy, and pain management clinics — Mayo Clinic and Cleveland Clinic are both longtime customers

📊 WellnessSpace Brands has delivered over 400 million sessions across 50+ countries and sold roughly 30,000 machines in the last eight years

❄️ Lunter built the first dry cold plunge prototype in 1992 — decades before cold plunging became mainstream

💰 When a Snap Fitness location raised membership dues by $10 after adding Wellness Space products, it lost only 2 members while 210 signed up for the add-on — a case study in pricing power

🏋️ Some Life Time locations run their equipment roughly 5,000 hours a year, out of a possible 8,000 — near-constant usage

🧖 The company's newest sauna uses no wood (to avoid bacteria and odor), circulates air for even heat, and layers in red light therapy at 630 and 850 nanometer wavelengths

💼 WellnessSpace Brands was self-funded until 2006, brought in private equity (Ilarion Partners), and has partnered with North Castle Partners since 2016 — now hiring aggressively after growing headcount by 60 this year

Jeff Byers, CEO of Momentous, returns to Future of Fitness for his third appearance to unpack how the brand grew revenue over 1,000% in three years while landing partnerships with all 32 NFL teams and 10+ Department of Defense contracts. Byers breaks down why Momentous walked away from a $500,000-profit product line over a science and brand-integrity call — literally scrapping $400,000 in inventory rather than sell it through — how the company is approaching its first-ever retail launch with Vitamin Shop, and why a $500,000 commitment to women's health research with Dr. Stacey Sims fits into a bigger 20-year brand strategy. From Arnold Schwarzenegger's endorsement to what AI search optimization means for consumer trust, this conversation is a masterclass in building a supplement brand built to outlast any single quarter.

Key Takeaways

📈 Momentous has grown revenue over 1,000% in the past three years and just landed its third consecutive Inc. 5000 appearance

🏈 The brand works with all 32 NFL teams and holds 10+ active Department of Defense contracts

💰 In 2024, Momentous discontinued FedOja — a $500,000 profit (not revenue) product — after deciding the science no longer supported it, scrapping $400,000 of existing inventory rather than sell through it

🏋️ The company began in 2018 as a DOD-funded biotech venture (Amp Human) before pivoting into consumer supplements when COVID hit

🎯 Momentous's roster of authoritative partners includes Arnold Schwarzenegger, Andrew Huberman, Tim Ferriss, Rich Roll, and Dr. Stacey Sims

🛒 Momentous launched its first-ever retail partnership this year with Vitamin Shop, using a "velocity over doors" strategy instead of chasing broad distribution

🧬 Momentous has committed $500,000 to women's health research alongside Dr. Stacey Sims

🤖 Byers explains why Momentous is intentionally avoiding a branded consumer AI chatbot — betting instead on showing up authentically inside tools like Claude and ChatGPT Our Sponsor: https://www.perfectgym.com/

Why do women lose bone density so fast after menopause — and what actually reverses it? Neurophysiologist and stem cell researcher Christian Drapeau (founder of STEMREGEN®) breaks down the biology behind bone and muscle aging, why strength training is the single most powerful lever for reversing the damage, and what most people get wrong about protein and collagen intake.

Key Takeaways:

• 🦴 Losing estrogen causes a "double hit" on bone: skeletal stem cells stop becoming bone-building osteoblasts while bone-degrading osteoclasts ramp up
• 🧈 Bone marrow can convert to fat tissue — some measurements put this as high as 15%, a major hidden driver of post-menopause bone loss
• 💪 Muscle growth is a stem cell process: satellite cells fuse into existing muscle fibers after training-induced micro-trauma to build new tissue
• 🏋️ Just 6–8 weeks of immobility measurably increases marrow fat in women — but resuming activity reverses it
• ✊ Grip strength is one of the single best predictors of long-term health and longevity
• 🧬 The body has "master" bone marrow stem cells (hematopoietic/mesenchymal) that migrate to different tissues and become bone, muscle, liver, or skin cells
• 🥩 Collagen peptides supply amino acids most diets are missing — critical for repairing connective tissue, not just "beauty"
• 🎯 Protein target discussed: roughly 1 gram per pound of body weight to support repair

JJ Creegan has helped build three of the biggest names in fitness — Planet Fitness, UFIT, and Orange Theory — and now works as a fractional COO/CEO helping emerging brands scale. In this episode, he and Eric dig into the K-shaped fitness economy, why the industry is "data rich but knowledge poor," and the exact visit-frequency formula that predicts member retention. They also cover the state of boutique fitness, the Pilates consolidation wave coming, and why the walls between fitness, medicine, and wellness are finally coming down.

Key Takeaways:

• 📊 Only 25% of the U.S. population holds a fitness membership — 75% of adults aren't engaging in fitness at all
• 💰 JJ's retention rule from his time at UFIT: getting a member to 10 visits in their first 60 days increased year-long retention odds by 50%
• 🚫 "You can't ever save a cancellation. You can only prevent it."
• 🔥 "Loyalty is fake. It does not exist in today's world. It's about relevancy."
• 🧗 If JJ had a blank check, he'd open a rock-climbing gym that integrates recovery and wellness — not a traditional gym
• 🏋️ Jet Set Pilates just signed its 400th license agreement and is set to open 150+ units this year
• 🩸 JJ's personal fight to get proactive bloodwork (testosterone) despite pushback from his own doctor
• 😴 The single biggest health upgrade in his last 5 years: being in bed before 9:30 PM for 7–7.5 hours of sleep

Online coaching is a $28.9B industry racing toward $120B by 2031 — but 71% of people who start an online fitness program quit within 90 days. In this episode, Eric sits down with Cody McBroom, founder of Tailored Coaching Method, who's built a 7-figure, ad-free coaching business over the past nine years without ever accepting a pay-in-full client. Cody breaks down the "identity-based coaching" model that took his team's client retention from 3-4 months to 14 months, why AI is reshaping how people find (and vet) a coach, and his genuinely nuanced take on GLP-1 drugs and the fitness industry's future.

Key Takeaways:

• 💰 Cody built Tailored Coaching Method into a 7-figure/year business with zero paid ads and a strict no-pay-in-full policy
• 🧠 Identity-based coaching (built around self-control, self-discipline, self-belief, self-respect) took his coaches' average client retention from 3-4 months to 14 months
• 💍 The surprising reason divorce rates rise when only one partner in a couple loses significant weight
• 🤖 ChatGPT Health logged 230 million health-related inquiries per week the month it launched — and Cody gets new client applications weekly sourced straight from AI search
• 🔍 60-65% of Google searches are now "no-click" — Cody explains how coaches can get cited inside AI summaries via AEO (Answer Engine Optimization)
• 💊 Cody's real position on GLP-1s/semaglutide: medically useful for extreme cases, but no substitute for the identity work required for lasting change
• 🥊 His mentor's blunt advice before going online: "train people for five years straight, and then you'll have the right to do that"
• 📈 Why he believes AI will "weed out" bad coaches rather than replace good ones

Christian Drapeau, neurophysiologist and stem cell researcher, joins Future of Fitness to explore the body's natural repair processes and how they change as we age.

Christian breaks down the balance between breakdown and renewal, how that balance shifts over time, and why a single underlying process connects so many different systems in the body. He also explains why bone health has more to do with collagen and flexibility than most people realize, and how estrogen and menopause relate to the body's repair mechanisms.

This conversation is for general educational and informational purposes only and is not medical advice.

ABOUT CHRISTIAN DRAPEAU Christian Drapeau is a neurophysiologist, stem cell researcher, and the Founder and Chief Science Officer of STEMREGEN. His work focuses on the role of circulating stem cells in the body and the factors that may influence their activity. He first proposed that stem cells function as part of the body's endogenous repair system in a 2002 paper and is the author of Cracking the Stem Cell Code.

Brian Keane has built a fitness empire that most coaches only dream about — four bestselling books, over 580 podcast episodes, a top 0.5% global podcast, and more than a thousand coaches trained through his mentorship programs. But before any of that, he was a primary school teacher who realized twenty minutes into his first day that he'd climbed the wrong ladder entirely. In this conversation, Brian breaks down exactly how fitness entrepreneurs, gym owners, and online coaches can stay relevant — and even thrive — as tools like ChatGPT and Claude start answering the same questions clients used to pay for. He walks through his SCALE framework for building an unshakeable personal brand, why chasing universal likability is killing more coaching businesses than AI ever will, and the wild story of how a plane ride home from an ayahuasca retreat turned into a 16-hour writing session that became his most recent book.

Key Takeaways:

🪜 Why Brian walked away from a stable teaching career the moment he realized "the ladder was against the wrong wall" 🤖 The exact reason you can't out-compete ChatGPT or Claude on results — and what to sell instead 🎯 Brian's SCALE framework (Storytelling, Core Offer, Amplify, Leverage, Evolve) for building a business AI can't copy 🥃 Why being "someone's shot of whiskey" beats trying to be everyone's cup of tea in coaching and branding 📈 The real reason his Fitness Business Podcast pre-qualifies clients before they ever book a call 🔥 The Facebook post he almost didn't share — and why it became the most-quoted line in his bestselling book 🌿 How a 3-night ayahuasca retreat led to writing an entire book in a single 16-hour flow state 🤝 Why "authentic connection" — not AI — is what actually keeps Brian up at night in this industry 💡 The one question his mum asked him that changed the entire trajectory of his career

Healthcare in America is stuck in a "sick care" model—we wait until people are already ill, then scramble to treat them. Dr. Gloria Winters, VP of Health Innovation at the YMCA of the USA, has spent the last year building something different: a community health operating system that pulls together your wearables, your medical records, and AI-driven insights into one place, so you actually know what to do with your health data instead of just staring at numbers. In this episode, she breaks down her "house" framework for the $5.6 trillion healthcare industry, why falls cost the country more than almost anything else, how she's working directly with HHS and the MAHA movement on preventive health policy, and why personal agency—not just data—is the missing piece in helping people actually change their behavior. If you've ever felt like your Apple Watch tells you everything except what you should actually do next, this conversation is for you.

Key Takeaways:

🏠 Healthcare is like a house — tech/data is the foundation, sick care takes up most of the "living space," and payers/regulators are the roof

💰 Falls are the #1 healthcare cost in the U.S. — more expensive than most people realize

📱 230 million people ask ChatGPT health questions every week — but personal AI health tracking is still fragmented and unverified

🔗 Interoperability is the real bottleneck — your wearables, scale, and medical records don't talk to each other, even though you use all of them

🎯 Personalization is the missing layer — knowing your heart rate hit 165 means nothing if no one tells you what to do next

🏛️ Dr. Winters is working directly with HHS, CMS, and the MAHA team on shifting national policy toward "upstream" preventive care

👁️ Human connection still matters — eye contact and relationship-centered care activate real neuroscience behind behavior change

🩺 The YMCA has quietly built medical clinics inside its facilities — including a Parkinson's exercise program that led medical providers to hire Parkinson's specialists

🌱 Her advice to gym owners: don't chase every trend — do an environmental scan of your community's actual health needs and pick one to solve

Something changed after 40. Recovery takes longer, energy dips, and the effort that used to work stopped working. You were told it's just aging. Neurophysiologist Christian Drapeau makes the case that it's something else entirely: the decline of your body's own repair system.

In this first episode of The Science of Vitality After 40, a four-part series with Christian Drapeau, host Eric Malzone explores the system almost no one talks about. Christian wrote the first paper proposing that our stem cells function as the body's repair system back in 2001, and here he explains what that system is, why it declines so early (by your early 30s you circulate a fraction of what you had at birth), and why the shift lands hardest on women in their 40s.

In this episode:

• What the repair system is, and why it works like a second immune system
• Why medicine treats the body's ability to heal as a "black hole"
• The steep, early decline in circulating stem cells and what drives it
• Why estrogen loss creates a "double whammy" for women at midlife
• Why weight-bearing exercise keeps emerging as the one clear lever
• What your circulating stem cell count may predict about how you age

Christian Drapeau is a neurophysiologist, a pioneer of stem cell mobilization, Founder and Chief Science Officer at STEMREGEN, and author of the bestselling Cracking the Stem Cell Code.
