Iron Culture presented by MASS

The trio is back on the heels of THE Sheffield 2024, the biggest powerlifting competition to date, which outdid its inaugural 2023 performance. Once again, the 12 best IPF-unequipped women and men clashed in a cross-weight class competition ranked by their total as a percentage of their respective world record. This meet incentivizes going BIG, rewarding cash prizes for both placing and breaking i...

The nerd super duo is back at it again. This time, Dr. Trexler plays Sherlock and Dr. Helms plays Watson in a discussion of how overtraining syndrome, metabolic adaptation, relative energy deficiency in sport, exercise energy compensation, body fat regulation, and more, are both distinct from one another, yet are all also closely related. Surprisingly, it took a couple meat head bodybuilders to no...

In classic Iron Culture throwback style, it's just Omar and Dr. Helms on this one, while the leader of Trex-topia is away at a conference. Omar and Eric give you the classic banter you love, go over reviews, and even engage in an off-the-cuff discussion of the health at every size movement. Then, they get to the meat of the conversation, a recent paper published on whether or not a lumbopelvic mov...

You've seen Iron Culture MASScasts before, but none quite like this.   In this very special episode of Iron Culture, we're co-publishing the most recent episode of MASS Office Hours, which is a live podcast run by the good people over at the MASS Research Review (Dr. Eric Trexler, Dr. Eric Helms, Dr. Mike Zourdos, and soon-to-be-doctor Lauren Colenso-Semple). The MASS crew does this live (and tota...

The trinity is reunited for the first time in 2024, with the Erics joining Omar for what is absolutely a monster episode. We tackle head-on the rise of antiscience in lifting. Currently, attacking exercise or nutrition science in your title or reel is an easy clickbait win for content creators, and you'll get bonus points via likes, shares, subscriptions, follows and positive comments if you also...

In our third interview following the 2023 natural bodybuilding season, we sit down with another historic champion with a truly outlier series of performances. This time, Australian phenom Beccy Pateman joined the Erics on Iron Culture to discuss her season, which culminated not only in her winning her WNBF pro card in both Figure and Fit Body, but also winning the WNBF pro world fit body title. As...

Layne Norton and Eric Helms have some similarities in their areas of interest and expertise as well as their career paths. However, they have different personalities and distinct approaches to science communication. That's what makes this one on one discussion between Eric and Layne interesting and relevant. Each approach has its pros and cons in terms of reach, impact, and effectiveness. Dr Layne...

Natalie Hays did what no natural bodybuilder has ever done before. Not only did she win her OCB pro card, to then go on and win the Yorton Cup pro title, but she also then won the Ms. America pro title, and then the WNBF Amateur World title to secure her WNBF pro card…but not satisfied, the next day she competed in the WNBF Pro Worlds, and won the professional women's bodybuilding title as well. W...

Happy Holidays cultists! We sincerely thank you all for joining us every week to explore the history, science and culture of the iron and we look forward to doing it more in 2024! In this episode, Omar and Helms discuss fat burners: supplements that supposedly enhance fat loss either by increasing energy expenditure and/or by blunting hunger and reducing energy intake. You've probably seen dozens...

We are joined today by pro natural bodybuilding world champion Dirk Emmerich. Dirk is one of the many emerging stars of the newest era of competitive natural bodybuilding. In 2021, in his very first bodybuilding season, he made history. He won his WNBF pro card in the most impressive way possible, by not only winning his class at WNBF Worlds but then - as a bantamweight - he won the WNBF world ove...

The Great Competition, 1901, Royal Albert Hall, London…this was the birthplace of modern bodybuilding. The one and only Eugen Sandow managed to persevere through multiple years of war, logistical setbacks, and a political and cultural climate that viewed physique displays as potentially indecent, sometimes immoral, and at worst, as illegal pornography, to host the first championship bodybuilding s...

We're back. We're so back (except for Dr. Trexler, he's sick …but he will be so back). Omar is getting his body composition tested in July and he has publicly guaranteed that he's going to have increased his lean mass by then. Likewise, Dr. Helms just publicly announced his monogamous commitment to bodybuilding and his push to become a pro champion now that he's turned pro. How are these not-so-sp...

The good Doctors Eric are still figuring out how to start episodes without Omar, and let's just say it's off to a rough start. But to their credit, they went on to deliver a monster episode even if Omar wasn't there to officially dub it so. In this conversation, Dr. Helms recaps the amazing battles and historic performances that took place at WNBF Worlds on Nov 18-19, where he participated as both...

It's hard to explain to those who haven't competed what it is about bodybuilding that can grip people and transform them. The near-spiritual experiences that some physique athletes gain through prep and competition are something shared regardless of division, federation, natural, or enhanced. In this episode, we sit down with Dr. Mike Israetel, not to talk sports science like you're used to, but t...

Leucine had a good run. It's been nearly two decades at the top, with the result being that even a casually aware meat head can explain that the muscle building quality of a protein source is tied, at least in part, to its leucine content and that you should probably consume protein sources with high leucine content and spread protein feedings evenly throughout your day. Further, if you just so ha...

This episode almost didn't happen. With Omar away, the Erics left to figure out how to do an episode of Iron Culture on their own, and nearly got stuck waiting forever for someone to say "Eric." But, cooler heads prevailed and they found their way into a thoughtful, introspective, and nostalgic conversation. While both Trexler and Helms ended up taking very similar paths in life when you look at t...

"Gotta eat big to get big brother!" "It's the off-season man, I'm on that SEE-food diet, heheh ya feel me?!!" It's been like this for decades in the muscle building world, and there's a ton of anecdotes that you gotta eat enough to grow. Certainly, we can't build muscle out of thin air. But given the modern understanding that body recomposition - at least in novice and early stage intermediate lif...

It's Eric-ception folks. Today, we put to bed two controversies. Not only the controversy as to whether or not Eric Trexler is vat-grown, as he seems to have at least SOME pop-culture knowledge, but also the controversy of whether or not Eric Trexler and Eric Helms are actually the same person. The last two episodes renewed this conspiracy theory due to the occurrence of the "new" host Eric Trexle...

The new co-host of Iron Culture, Eric Trexler, is back with another (monster) episode. In this episode we take a look at everyone's favorite hormone, testosterone.  Specially, Dr. Trexler examines the role of maconutrient changes on testosterone levels. How does fat & carbohydrate intake impact a person's testosterone? We also explore body composition differences and how this can have an even larg...

This is a monster episode. Newly added co-host Eric Trexler details his impressive credentials, groundbreaking new line of research and perhaps most importantly, the best way to effectively execute a single leg take-down on an unsuspecting person.  His new appointment at Duke University will be looking in part at the topic of today, exercise energy compensation. It turns out that calories in, calo...

Fresh off his historic performance at USAPL Mega Nationals 2023, Austin Perkins joins Iron Culture to share his story of how in just two short years he exceeded Taylor Atwood's 2021 record performance which many thought would stand for years to come. Austin Perkins totalled 851kg in the under 75kg raw men's division, totalling more than the 82.5kg winner, and importantly 12.5kg more than Taylor At...

It's been a while since the duo atop the pyramid just sat down for a good one-on-one chat, as we've had awesome guests on for the past 6 episodes. But what did we talk about as the two of us sat atop the pyramid? Believe it or not, ending our relationship as Eve known it, by bringing a third host on top of the pyramid with us…and not atop the adjacent obelisk, and not on the one step below us, but...

The Iron Culture alumni tour continues with the four year anniversary of the last appearance of Cliff Wilson, who returns to Iron Culture after another four years in the trenches to share his perspectives on coaching. Simply put, Cliff probably has the most impressive coaching resume of any physique coach in the game. Most interestingly, he sees himself as an evidence-based coach. But that's not n...

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 "headstron...

It's the four-year anniversary of the last appearance of then MR. Alex Kolliari-Turner, now DR. Alex Kolliari-Turner, who returns to Iron Culture to share the results of his now-completed Ph. D. research on the long-term performance-enhancing effects of anabolic steroids (if any). A lot has changed in this burgeoning area of research, as it hinges on a theory of muscle physiology: myonuclear domai...
