Number 1: Building a Fitness Empire: Business Lessons, Zone 2 & Recovery Trends with Don Saladino — #403
Don Saladino is a New York-based coach and health entrepreneur who has trained A-list clients like Ryan Reynolds, Hugh Jackman, and Blake Lively since founding Drive495 in 2005. Don Saladino has spent nearly three decades training A-list stars like Ryan Reynolds and Hugh Jackman — and in this episode, he shares the single business lesson he wishes he’d learned sooner. He and Dr. Mike also dig into why Don closed his $2M-overhead NYC gym, how tracking respiratory rate reshaped his approach to Zone 2 training, and the sobering personal loss that changed how he views performance enhancers. Expect to learn why Don stopped over-certifying and started looking at what’s leaking in his business, how he built 17 years of trust with a client like Ryan Reynolds, the real financial toll of running a NYC gym (think $1M rent and $2M overhead), what tracking respiratory rate taught him about Zone 2 training volume, his honest take on performance enhancers at 49 (natural), and the personal loss that reshaped how he views unsupervised PED use, and much more.

Number 2: Episode 404: Whole-Body MRI, CT Scans, and What Imaging Can Tell You — Matthew Paul Clemons, MD
Matthew Paul Clemons, MD, is a diagnostic radiologist specializing in nuclear medicine and body imaging. He is Head of Nuclear Medicine at Radiology Partners Houston and a rectal and prostate cancer specialist. Whole-body MRI promises a detailed look under the hood—but what can a quick screening scan actually see, miss, and send you chasing? Dr. Paul Clemons explains why a whole-body MRI is a limited study, how incidental findings can lead to further tests, and why standard screening remains the better choice for most people. Expect to learn how MRI creates images and why scan protocols take time, why open MRI systems can have important image-quality limits, how PET/MRI adds functional information, why CT and MRI can be complementary rather than redundant, how radiation and implanted devices factor into decisions, why spine findings do not always match symptoms, when conservative care deserves consideration, and where DEXA versus MRI can be useful for tracking body-composition trends.

Number 3: AI Disclosure, Deepfakes & the Death of Expertise — Dean Guedo & Jeb Stuart Johnston — #404
Dean Guedo is an Edmonton, Alberta-based online nutrition coach and strength/nutrition professional with roughly a decade in fitness, athletics and strength sports, and Jeb Stuart Johnston is a National Board Certified Health & Wellness Coach and the Charleston, SC-based founder of Food on the Mind, specializing in emotional eating and food obsession. Dean and Jeb join Dr. Mike T Nelson for their yearly AI check-in, getting into whether creators should disclose AI use and why deepfaked video is a very different beast than AI-assisted writing. The conversation ranges into dead internet theory, why so much hard-won fitness expertise never made it onto the internet at all, and why demanding physical skills may become more valuable, not less, as AI accelerates. Expect to learn whether creators should disclose their AI use and why deepfaked video is a fundamentally different risk category than AI-assisted writing, why LLM writing may have already "peaked" and regresses toward the average, why fitness's hard-won oral tradition (Charlie Francis, Louie Simmons, old forums) never made it onto the internet at all, why oral defense of your own thinking may be the most AI-proof skill you can build, and why demanding physical skills could become more valuable — not less — as AI accelerates, and much more.

Number 4: VO2 Max, Zone 2 Training & the Psychology of Human Performance — Ben Skutnik — #402
Dr. Ben Skutnik, PhD, CSCS*D, NSCA-CPT*D, is an Assistant Professor of Kinesiology and Human Performance Lab Director at Butler University and Head of Nutrition Coaching at Power Athlete. Dr. Ben Skutnik joins the show to separate fact from fad in aerobic training, debunking zone 2 hype and explaining why VO2 max matters but isn't everything. Expect to learn why reading scientific literature is its own skill, how uncontrolled variables quietly derail hypertrophy and menstrual-cycle training research, why treating people as fragile backfires, why anecdote in human performance often outruns the research, how "closing the loop" with clients beats chasing mechanisms, what the Norwegian 4x4 method gets right (and what most zone 2 research gets wrong about training zones), and how to actually build VO2 max with the critical power model, and much more.

Number 5: Getting Back to Nutrition Basics: Gut Health, Micronutrients & Training with Zach Moore
Zach Moore is a nutrition and exercise coach based in southern Indiana, coaching clients online and in person. Zach cuts through the noise of complicated programming and diet protocols to get back to what actually works — minimalist strength training, honest macro-setting, and paying attention to gut health and micronutrient status before chasing anything fancier. Expect to learn how to build serious strength with far less training volume than you think, why chasing perfect programming conditions is often a waste of energy, how Zach sets carbohydrate and macro targets for real-world clients, when (and when not) to bother with micronutrient or gut testing, and why micronutrients matter even on restrictive or elimination diets, and much more.
