    Episode 362: Beetroot, Blood Flow, and Freaks of Physiology with Dr. Eric Trexler

    In this episode of the Flex Diet Podcast, I’m joined by my good friend Dr. Eric Trexler, exercise scientist, educator, and Director of Education at Stronger by Science, for a wide-ranging, no-BS conversation on what physiology actually looks like in the real world. We dig into beetroot juice, nitric oxide, and “pump” supplements, why the blood-flow story is usually oversold, and why neuromuscular function and calcium handling may matter far more than chasing a swollen muscle. We also talk about why most supplement mechanisms sound great on paper… and quietly fall apart once you look at healthy humans who already function pretty well. From there, the conversation expands into human variability, elite athletic outliers, and why normal distributions actually guarantee that “freaks” exist — whether people are comfortable admitting it or not. We also unpack NEAT, energy expenditure, and why exercise doesn’t scale linearly for fat loss, including how the body aggressively manages its energy budget when stress or activity gets too high. If you care about performance, body composition, or just understanding how the human system really works, this episode will recalibrate a lot of assumptions.

    Episode 361: Maximizing Athletic Performance and Recovery with Dr. Jeremy Bettle

    In this episode of the Flex Diet Podcast, I sit down with Dr. Jeremy Bettle, a performance director and applied sports scientist, to dig into what actually moves the needle for performance, recovery, and long-term resilience. We cover everything from high ankle sprains and injury prevention to smarter load management, and why understanding stress, recovery, and tissue capacity matters far more than chasing random training trends. Dr. Bettle shares insights from years of work across the NHL, NBA, and international sport, along with how elite performance systems can — and should — be translated to non-elite humans who want to train hard, recover better, and keep doing this for decades.

    In this episode of the Flex Diet Podcast, I sit down with my good friend Aram Grigorian from the Real Coaches Summit to talk shop on what actually matters in coaching today. We dig into body composition and weight loss, why consistency still beats novelty, and how to think more clearly about calorie tracking without losing the forest for the trees. We also get into industry trends, client compliance, and why live, in-person events remain one of the most underrated tools for becoming a better coach.

    Episode 359: Debunking Women’s Fitness Myths with Dr. Lauren Colenso-Semple

    In this episode of the Flex Diet Podcast, I sit down with Dr. Lauren Colenso-Semple to cut through the noise and tackle some of the most persistent myths in women’s fitness. We break down where misinformation shows up in popular programs, why overly complicated plans often backfire, and what the science actually says about fasted training and low energy availability.  We also get into hot topics like cold water immersion and cortisol, real sex-based differences in training responses, and why women’s fitness research is still so challenging to conduct well. If you’re looking for practical, evidence-based guidance instead of hype, this episode will help you train smarter and with more confidence.
