The duo’s recent pilgrimage to Texas ended with a trip to the state-of-the-art Texas Tech University body composition lab led by Dr. Grant Tinsley. Eric and Omar went through a battery of body composition assessments and had their RMR tested there, and Eric’s second epic duel with the Bod Pod went down. This duel resulted in only partial redemption for Eric, and we also learned just how “headstrong” Omar truly is. In this episode Grant joins Iron Culture to discuss the findings of the trip and all the nuances of body composition testing to help us understand the sometimes non-intuitive results the team got, and more broadly the pros, cons, strengths and weaknesses of the various body composition tests that are available. 00:00 The controversy that the Iron Culture won’t stand for 08:03 Welcoming back on the podcast, Dr Grant Tinsley 13:27 Understanding how body composition is estimated by multiple compartment methods 31:20 The applications of bioelectrical impedance for physique sport peaking 37:00 All about DEXA and how it fits into the six-compartment model 57:24 Explaining errors within body composition assessment  1:08:23 How measurements can be affected and the future of body composition testing 1:19:15 How metabolism is measured and metabolic adaptation 1:30:55 Thanking Dr Grant Tinsley and closing out (The BodPod) Website https://granttinsley.com/  Instagram @grant_tinsley_phd https://www.instagram.com/grant_tinsley_phd/ Twitter @GrantTinsleyPhD https://twitter.com/GrantTinsleyPhD ResearchGate https://www.researchgate.net/profile/Grant-Tinsley

Ep. 239 - All About Body Composition & Body Fat (feat. Dr. Grant Tinsley)

Iron Culture was started by Eric Helms and Omar Isuf 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. The lifting community has become fractured over the last ~70 years and this Podcast will attempt to explore the fundamental threads that unite these different tribes.  The Podcast focuses on dispensing practical, useful information to the listener, bouncing from history, to philosophy, to contemporary lifting culture issues, to science. This can range from teaching the audience about lifting, programming, nutrition, supplements/PEDs and the history of lifting culture. The format includes casual conversations between the two hosts on a variety of topics, discussions with a panel of experts and interviews with authoritative figures in the lifting community.

Wes Goodman recently completed his PhD in Exercise and Nutrition Science with an emphasis in Biomechanics and Motor Control at Montana State University under Dr. David Graham with our very own Dr. Helms on his committee as well. But he’s more than an academic, he’s a certified strength and conditioning specialist, gym owner, power lifter, strong man and Highland Games competitor! He studied how musculoskeletal modelling can help us understand the nuances of how the body performs squats. In this episode you’ll learn about the theory and application of motor control to lifting, the limitations of common biomechanics studies, and how modelling helps us understand that muscles can influence joints they don’t actually cross, and to Omar’s dismay, that a calf raise might actually be a squat accessory exercise! 00:00 Addressing the controversy before introducing our guest Sooper Gforce Iron Culture Ep 269- Are Social Media PhDs Ruining Fitness?

Ep. 273 - Biomechanics for Powerlifting feat Dr. Wes Goodman

The man, the myth, the legend, Mike T is back! Fresh off a 900kg total, an 800lbs deadlift, and placing just off the podium at Powerlifting America National by bodyweight, Mike T is showing how much longevity can be had for the lifelong lifter, even at the highest level. We’ve only got a penlight in this pitch-dark morphing cave, but that’s apparently all you need. Join us on this episode where we discuss mental maturity and growth as a lifter, Mike’s journey and his future plans in equipped lifting! 00:00 Introduction to a homecoming episode Iron Culture Ep. 4- Periodization & Autoregulation Roundtable https://www.youtube.com/watch?v=RIVw1OxvZUA 07:15 Catching up on Mike T’s achievements and competing equipped Iron Culture Ep. 46- Powerlifting: Raw vs Equipped Lifting (Ft.

Ep. 272 - Mike Tuchscherer: Peaking  After 20 Years of Powerlifting

Trextopia, this is your episode. We peel back the layers of pro natural bodybuilder, exercise science researcher & co-host of Iron Culture, Eric Trexler. Learn how he got into lifting, what low bar squatting 500lb ATG will do to your body & why there might be more controversy in Iron Culture’s near future. This might be the peak of Iron Culture but Trexler is no fan of peak weeks. 00:00 Introduction to an episode with Eric without the other Eric 03:06 An inside peak into Trexler’s day as a scientist (Trex lore)  09:42 Trexler’s foray into powerlifting 19:47 T-Nation and what informed Trexler’s training practices 27:12 Wrestling, lifting, and experimenting with training 36:02 Change of perspective: different approaches to training 42:44 The evolution of Trexler’s training and getting into science 48:37 “Optimisation” for bodybuilding and peaking (Helm’s hat cameo) 1:00:45 The pros and cons of different approaches 1:04:53 Diving into different research topics and the recent challenges in Trexler’s fitness journey  1:16:57 Growing and learning from the experiences (and the return of the T-Rex) 1:30:41 Closing out this monster episode 

Ep. 271 - Powerlifting, Natural Bodybuilding & Science (Eric Trexler’s Journey)

We here at Iron Culture have been on a mission to better inform you, dear listener, as to the inner workings of science. From what goes on in the lab itself, to the publication process, to dissemination, to eventual meta-analysis, the challenge of interpretation and communication of science, the optimistic promises of open science, and the increasing focus on replication, it’s been a hopefully eye-opening and overall encouraging discussion. However, while the scientific method is inherently self-correcting, the apparatus of science is far from perfect and there is a big problem with its principle tool of correcting the peer-reviewed record: retraction. What leads to a paper being retracted? What is the process? How does it impact the literature? Most importantly, does it effectively change the understanding of the science in the community the studies are meant to serve?

Ep. 270 - Scientific Retractions Aren’t Working

Whitney Houston said it best: “I believe the children are our future, teach them well and let them lead the way.” Here at Iron Culture, we’re old, irrelevant and out of touch. But, we believe in platforming the next generation of educators to carry on the torch (or at least pandering so they’ll platform us in return when we can no longer pay the bills). In this Roundtable we’re joined by Dr. Milo Wolf, Dr. Pak, and first-time guest Max Coleman, to discuss the challenges of growing a following using social media in 2024 as an evidence-based content creator. The game has changed what worked for us, won’t be as successful, and striking the right balance is not easy, and getting it wrong comes with lashback. Are we all just doing more harm than good?
