    Ep 381 - Q&A: GLP-1s, Tendon Training, & Rep Ranges

    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

    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.

    Ep 378 - Social Media Protein Debates

    Eric Trexler and Eric Helms recently found themselves in the middle of a debate about optimal protein intakes, all initiated by a social media post from Stu Phillips (a leading researcher in the area). In this episode, they dive into how that scientific discourse played out, the nuances of protein intake, and the implications for recreational lifters and bodybuilders alike. They discuss the complexities of scientific data interpretation, public messaging, and practical recommendations for optimal protein consumption.

    Ep 377 – MRV/MAV, Diet Breaks & Refeeds

    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).   If you're in the market for some new (ultra-high-quality) gym gear or apparel, be sure to use code "MRR10" for a 10% discount over at elitefts.com    Iron Culture is proudly presented by the MASS Research Review.

    Ep 376 - Weight Loss Resistance

    Join us for a rare Iron Culture episode with co-hosts who are not only on the same continent, but actually in the same ROOM. Helms and Trexler are in Australia for the Sports Nutrition Association Annual Conference, so they got together to record an episode about Trex's presentation topic: resistance to weight loss. Specifically, why being a true "outlier" who is resistant to weight loss efforts is quite rare, particularly when looking at the energy expenditure side of the equation.
