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.

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.

A child's future begins long before the first words, first steps or even the first smile. In the span of just 1,000 days, billions of neural connections are formed, and the foundation for lifelong health, learning, and resilience quietly takes shape. Pediatricians understand the critical nature of early development, and they translate that message to parents, helping guide, nurture, recognize risk and shape outcomes that can last decades. To explore this fascinating time in a child's life, we are joined by two experts. Caroline Dias, MD, PhD, and Annie Helms, MD, both specialize in developmental and behavioral pediatrics here at Children's Hospital Colorado and are assistant professors at the University of Colorado School of Medicine. Dr. Helms also leads the BLOSSOM Clinic at Children's Colorado. Some highlights from this episode include: How small things can have the biggest impact in these 1000 days The importance of supportive caregivers The balance of nature versus nurture Easing parent's minds that they aren't "doing enough" For more information on Children's Colorado, visit: childrenscolorado.org.

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.

One of the means of helping to overcome white supremacy is for those of us who are white not only to learn to tell our own race story, but also to take over the responsibility of holding each other as white people accountable when we act and speak in ways that reveal our racial biases or that we are shaped by white supremacy beyond our awareness. As individuals we need to learn and train ourselves how to recognize and become more fully aware of when our thoughts, assumptions, words, and actions cause racial harm. We also need to be more willing to confront and correct other white people when they do the same. It helps to have white role models for this process. My guest for this episode provides such a role model. Greg Jarrell is a cultural organizer with QC Family Tree in the Enderly Park neighborhood of Charlotte, North Carolina. He works with words and music to impact housing and neighborhood justice issues. Jarrell writes about theology and history and co-leads Carolina Social Music Club, a popular jazz band. He and his wife, Helms, are ordained ministers and are raising two sons. Greg is the author of two books that will be the focus of our conversation. They are: A Riff of Love: Notes on Community and Belonging Our Trespasses: White Churches and the Taking of American Neighborhoods You can learn more about Greg from his website: gregjarrell.com The intro and outro music for this episode is from a clip of a song called ‘Father Let Your Kingdom Come’ which is found on The Porter’s Gate Worship Project Work Songs album and is used by permission by The Porter’s Gate Worship Project.

Body recomposition is one of the most contested concepts in physique development — and one of the most misunderstood.The traditional dogma says you have to pick a lane. You're either bulking or you're cutting. You can't gain muscle in a deficit. And once you're past the beginner stage, recomp isn't on the table.But the research over the past several years has made it increasingly clear that this framing is an oversimplification of how energy balance actually translates to body composition. And there are specific levers that, when pulled correctly together, can drive recomp outcomes in trained individuals who've spent years thinking it wasn't possible for them.On this week's episode of the CHASING CLARITY HEALTH & FITNESS PODCAST, I'm following up on my recent conversation with Dr. Eric Helms with a solo deep-dive into the two topics we didn't get to cover — the most recent body recomp research published this year, and the three primary levers I pull with my clients to actually drive recomp outcomes in the real world.This episode is for:Trained lifters who've been told recomp is no longer on the tableCoaches who want a clear framework for programming recomp phasesAnyone stuck between cutting and bulking and ready to try a different approachListeners who heard the Helms episode and want the practical playbookHERE'S WHAT WE COVER:A FOUNDATIONAL RECAP OF WHAT BODY RECOMP IS & THE 3 FORMS IT CAN TAKEA DEEP DIVE INTO THE LATEST RECOMP STUDY BY VARGAS-MOLINA ET AL. 2025LEVER 1: DEFICIT SIZE & WHY SMALLER DEFICITS BEAT AGGRESSIVE ONES FOR RECOMPLEVER 2: PROTEIN INTAKE & THE TIERED APPROACH I USE BASED ON BODY FAT LEVELLEVER 3: TRAINING DOSE & THE DIFFERENCE BETWEEN WORKING OUT VS. TRAININGWHY MOST LIFTERS HAVE NEVER TRULY TRAINED CLOSE ENOUGH TO FAILURE TO DRIVE RECOMPHOW TO PULL ALL THREE LEVERS IN ALIGNMENT TO MAKE RECOMP HAPPENThis is the practical follow-up to the Helms conversation — the actionable playbook for anyone who wants to take their recomp efforts seriously.If you've been spinning your wheels between cutting and bulking without making the progress you want, this episode will give you the clarity you've been missing.
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.

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. So in this episode, Helms and Trex take a closer look at two key topics: maximum recoverable (or adaptable) training volume, and various approaches to strategically manipulating leptin levels (such as refeeds and diet breaks).
