  Ep 386 - Sleep, Hypertrophy, and Creatine 20.08.2026 1ч 19мин

  Trexler and Helms dig into sleep and how it intersects with body composition and supplementation. They open on the sleep-and-lifting landscape, then work through the frequently cited 2010 study on insufficient sleep and fat loss, laying out its design and the details behind its dramatic-sounding numbers. From there they discuss what the broader literature does and doesn't establish, the acute effects of sleep restriction on power, skill, and pain perception, and observational data — including sleep patterns in hunter-gatherer societies and among elite athletes — plus the relationship between sleep duration and sleep efficiency. The back half turns to supplementation. They trace the history of research on creatine and sleep, from early findings that creatine might reduce sleep need to newer work on brain creatine under sleep deprivation. This leads into a crossover trial testing caffeine and creatine against a sleep-deprivation cognitive challenge, its findings on rugby passing accuracy, and how to interpret an isolated positive result on a little-studied question. They cover a more recent high-dose replication, then close with the practical side — creatine dosing, the common report that creatine disrupts sleep, and caffeine timing — before wrapping up.

  Ep 385 - Do Studies on Untrained Lifters Apply to Trained Lifters? 12.08.2026 1ч 18мин

  Trexler and Helms dig into Helms's new MASS article, "Are studies on untrained lifters irrelevant to trained lifters?" It's built around a new umbrella review by Andy Fry and colleagues. The recurring internet claim is that most exercise research is done on untrained people, so a trained lifter is "built different" and the findings don't apply. The hosts unpack why that's mostly wrong. They start with the messy problem of defining how "trained" someone is. Then they discuss Fry's review, which reports that roughly 70% of resistance training study participants are sedentary or untrained, with fewer than 500 out of nearly 19,000 participants counting as genuinely well-trained. But the key focus of the episode is that this doesn't invalidate the research: what makes a beginner grow more will also make an advanced lifter grow more — the difference is rate, not mechanism.

  Ep 384 - Is Ultrasound Lying About Your Gains? 29.07.2026 1ч 22мин

  A methods-focused episode about how muscle and body-composition measurements can mislead you when reading the research. The main event is a new Balshaw and colleagues paper concluding that ultrasound muscle thickness is a poor index of MRI-measured muscle growth. Trexler and Helms argue this shouldn't be read as "throw out all ultrasound research" — the real culprit is that muscle thickness is a crude one-dimensional snapshot with measurement error large enough to swamp the small changes seen in typical short studies, whereas MRI captures growth in more dimensions with better fidelity. They walk through why comparing across different dimensions and different devices matters, what researchers can do about it (bigger doses, larger samples, multiple measurements), and use the famous "sleep restriction kills your gains by 60%" study as an example of over-reading a tiny difference in ten people. The second half turns to DEXA. Prompted by someone confused that DEXA fat mass didn't line up with the 3,500-calorie rule, they explain DEXA's three-compartment model, why it measures fat mass rather than adipose tissue, and why lean soft tissue readings are so sensitive to hydration. The practical upshot: don't build your worldview on a kilogram of day-to-day DEXA noise, be cautious using DEXA to estimate energy status, and understand that flattening a three-dimensional body into a two-dimensional scan introduces real limits. They close with an extended, tongue-in-cheek bit about trademarking "muscle journey" dimensions. Iron Culture is proudly presented by the MASS Research Review.

  Ep 383 - Q&A: Imbalances, Fatigue, & REDs 22.07.2026 1ч 5мин

  In today's Q&A episode, the Erics work through a few listener questions. First they tackle upper/lower body imbalance — why lagging body parts usually call for improving training quality before adding volume, and why standout muscle groups can be maintained on surprisingly little work. Next is a long discussion on managing fatigue and exercise sequencing in high-frequency, non-traditional splits, including why the "48 hours between muscle groups" rule is more dogma than requirement and how to think about fatigue as continuous rather than categorical. The episode closes with a multifaceted question on REDs (relative energy deficiency in sport) — what it is, its warning signs, and the limits of what bloodwork can actually tell you.  Iron Culture is proudly presented by the MASS Research Review.

  Ep 382 - The Science of Building Bone (ft. Dr.Lora Giangregorio) 15.07.2026 1ч 26мин

  The Erics sit down with bone health expert Dr. Lora Giangregorio, a professor of kinesiology at the University of Waterloo, to unpack what's actually known about how bone adapts to resistance training. The conversation covers why bone changes so slowly, the many sources of measurement error in DEXA scans, and why so much of the exercise-and-bone literature is underpowered and hard to interpret. Dr. G makes a central practical case: for building bone, the message shouldn't be "lift heavy" but rather "work hard." Emphasizing high effort over intimidating absolute loads lowers the barrier to entry, especially for older and osteoporotic populations, while still driving progressive overload. She argues the best current bet is combining moderate-to-high-intensity resistance training with impact work, introduced gradually on a foundation of strength. Along the way she debunks popular but weakly supported interventions, including weighted vests and whole-body vibration platforms, and discusses the difference between biological aging and simple chronic inactivity in bone loss.

  Ep 381 - Q&A: GLP-1s, Tendon Training, & Rep Ranges 01.07.2026 1ч 16мин

  Trexler and Helms open with an overview of the new MASS issue (body recomposition, a protein consensus paper, reverse dieting) and a powerlifting World Championships recap before diving into a rapid-fire listener Q&A. Along the way they tackle whether protein needs scale with training volume, the science behind a supplement that's been called "Nature's Ozempic," evaluating protein quality based on food labels, dieting while chasing endurance adaptations, protecting tendons and bone when shifting from powerlifting to bodybuilding, and the myths around rep ranges and muscle shape. The back half centers on GLP-1 drugs like tirzepatide — their surprising off-label effects, who's actually a good candidate, and whether they should be banned in natural bodybuilding — before closing with a rapid-fire round on lengthened partials and the volume-versus-frequency question.

  Ep 380 - Bulking, Cutting, and Recomping 25.06.2026 1ч 20мин

  In this Q&A episode, Eric Trexler and Eric Helms open with a recap of their trip to Norway and announce a new MASS partnership with AFPT International. They then work through a string of listener questions that end up forming a surprisingly cohesive arc: how much total daily energy expenditure actually varies between people, RED-S and low energy availability, what really drives satiety, and a deep dive into building or retaining muscle in a calorie deficit. The back half tackles body recomposition head-on, why the rigid "bulk vs. cut" mindset comes largely from competitive and enhanced bodybuilding, and how natural powerlifters demonstrate that recomp is closer to the default state than most people assume.

  Back in episode 375, Helms and Trex briefly mentioned a few "evidence-based fitness" topics for which their views have evolved over the years. In hindsight, they didn't give a few of those topics the time, attention, and explanation they deserve.
