Iron Culture presented by MASS
Hosted by MASS Research Review · EN
Iron Culture was started as a means of exploring the world of physical culture and attempting to distill a unified philosophy of lifting and to help listeners find greater meaning from the iron. It focuses on dispensing practical, useful information to the listener, bouncing from history, to philosophy, to contemporary lifting culture issues, to science.

Ep 383 - Q&A: Imbalances, Fatigue, & REDs
5d ago01:05:42Tap to summarizeIn 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.

Transcribe →Ep 382 - The Science of Building Bone (ft. Dr.Lora Giangregorio)
2w ago01:26:23Tap to summarizeThe 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.Iron Culture is proudly presented by the MASS Research Review.

Transcribe →Ep 381 - Q&A: GLP-1s, Tendon Training, & Rep Ranges
4w ago01:16:15Tap to summarizeTrexler 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.Be sure to use code "MRR10" for 10% off your order at elitefts.comIron Culture is proudly presented by the MASS Research Reviewmassresearchreview.comChapters0:00 — Intro, audio gremlins & the new MASS issue6:40 — Powerlifting news: World Championships & squat records11:48 — Do protein requirements scale with training volume?16:59 — PGX: is "Nature's Ozempic" actually legit?22:49 — Protein quality & % Daily Value on food labels26:47 — Chasing endurance adaptations while dieting in a deficit36:52 — Protecting tendons & bone when leaving powerlifting45:37 — Rep ranges, muscle "hardness" & fiber-type myths50:21 — Tirzepatide & GLP-1s: are they really the wonder drug?1:01:08 — Should GLP-1s be banned in natural bodybuilding?1:11:11 — Rapid fire: lengthened partials & the volume/frequency question1:15:39 — Wrap-up & sign-off
Transcribe →Ep 380 - Bulking, Cutting, and Recomping
Jun 2501:20:51Tap to summarizeIn 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.Iron Culture is proudly presented by the MASS Research Review.

Transcribe →Ep 378 - Social Media Protein Debates
Jun 301:19:06Tap to summarizeEric 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.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.comIron Culture is proudly presented by the MASS Research Review.

Transcribe →Ep 377 – MRV/MAV, Diet Breaks & Refeeds
May 2701:12:11Tap to summarizeBack 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).

Transcribe →Ep 376 - Weight Loss Resistance
May 2001:06:50Tap to summarizeJoin 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.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.comIron Culture is proudly presented by the MASS Research Review.
