Iron Culture

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 movement screen can predict back pain in powerlifters. What can this study teach us about the links between pain, injury, and movement in powerlifting?

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 totally free) Q&A every Wednesday night on YouTube. They also offer episodes to all major podcast platforms so you can catch the replay at your convenience.   In this episode of MASS Office Hours, Dr. Eric Trexler and Dr. Mike Zourdos answer questions submitted by listeners and viewers in the live chat. Topics include response variation, individualizing training, movement screens, rest days, protein intake recommendations and consistency across the week, the interference effect, exercise variation and joint pain, muscle and strength loss during deloads, volume cycling and “resensitization,” the effects of alcohol on

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 manage an appeal to what serious lifters “have always known”. Why is this occurring? Is this even a problem? Is it a good thing because those in the exercise and nutrition science ivory towers are so out of touch? If it is a problem, does it lie with science itself, how science communication occurs, or perhaps the expectations put on science? In this episode we discuss all this and more, and it gets spicy! 00:00 Erics… The benefits of living in New Zealand and reading two monster reviews 12:32 Clickbait titles and the anti-exercise science brigade 25:08 The historical perspective 32:26 A monster monster episode: comm

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 we’ve discussed, for an athlete to turn pro in the WNBF and win a pro world title in the same season is incredibly rare. Further, the weekend prior to WNBF worlds, Beccy won the Professional Natual Olympia Figure title in the INBA/PNBA. Winning two world titles, relatively early in one’s career, in two different federations, and in two different divisions nonetheless, is an even more incredible feat, which only a handful of athletes have ever done in the history of natural bodybuilding. Indeed, the athletes who have done so have, in most cases, gone on to become legends of natural bodybuilding. How did Beccy do it?

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 Norton joins Iron Culture for the first time in this episode to candidly discuss the importance and challenges of science communication in the modern age where good information is abundant, but good interpretation is sparse. There is a lot to think about in this interview for both content creators and consumers, so make sure to tune in! 00:00 Iron Culture… Layne… (Norton) 06:18 Layne’s philosophy for disseminating science and who to listen to 23:10 Competing with non-evidence-based personalities and effective marketing 42:59 Differing approaches and target audiences 47:12 Layne’s approach to science communication  5

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. Without any qualifiers, this series of wins at the biggest shows in natural bodybuilding is unprecedented and downright incredible. But, consider that she did this in her very first season competing! In this episode the Erics sit down with Natalie to talk through her historic competitive season and learn just how unique she is, both in her psychology and relentless dedication to her craft, but also in her physiology. Further, like other young champions of late, we learn how she was patient in her decision to eventually step on stage, and was awarded immensely. This is not one to miss for bodybuilding fans! 00:00 We go

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 marketed over the years if you’ve been around the fitness industry for any decent length of time, but do they actually work? In this episode we discuss the science of fat burners. A recent study coming out of none other than Dr. Grant Tinsley’s lab showed that a commercially available thermogenesis fat burner did seem to do something, but how meaningful it was and whether it actually would lead to fat loss is up for debate. Finally, we discuss where the data lies broadly on this whole class of supplements. 00:00 Not off to the best start… Fuelling conspiracy theories and reviewing reviews 11:31 Getting into the topic

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 overall amateur bodybuilding title, the first bantamweight ever in the then 32-year history of WNBF Worlds to do so. This year, Dirk made just as much of an impact in his pro debut as he did in his bodybuilding debut, as he medalled in multiple pro shows, including winning the pro lightweight WNBF Valhalla title. Finally, his season culminated in winning the WNBF Pro Worlds Lightweight title in the largest lightweight pro class in history, consisting of 16 competitors. How did he do it? What type of planning, mentality, talent, and coaching does it take to be so successful in your debut seasons as an amateur and profess

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 show to find the “best built man in Britain and Ireland”. To even compete, entrants had to place top three in a full series of regional qualifiers where hundreds upon hundreds of athletes battled against one another in the years prior. Further, to even enter these regional qualifiers, entrants had to send in their pictures to Eugen Sandow’s magazine for initial screening. The eventual championship in 1901 was truly a spectacle. Nearly ten thousand attendees packed Royal Albert Hall to the brim, an astonishing number that rivals the attendance of any modern bodybuilding competition…even the Olympia. Indeed, this histor

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-spring chickens going to do it? More importantly for you dear listener, how are you going to do it if you’ve been in the game a while? It’s a complex question, requiring us to define what advanced even means, to understand whether there actually is such a thing as a “natural limit”, both technically and functionally, and to understand the complexity of such an assessment. Does it apply to your whole physique, or is it body part specific? Is there a limit on your muscle mass that is universal, or does it differ at various levels of body fat? More so, one must figure out what tools we even have to assess one’s proximity

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 a coach and athlete. Then, Dr. Trexler and he cover a couple of relevant and interesting research papers, the first, covered by Dr. Helms explores the “whys” underlying the motivations competitive bodybuilders have to live the life they lead. The second, covered by Dr. Trexler, explores the often-repeated claim that when you diet, you’ll lose ~25% of your weight as lean mass. Is this true? And if it is, for whom and in what circumstances?

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 to talk about what lies at the heart of the sport. Mike has been pushing forward through multiple seasons in his attempt to become an IFBB pro bodybuilder, an incredibly challenging feat that requires tremendous sacrifice and drive. What fuels a journey like that? What does a competitor experience - highs and lows? What do they learn, and how do they change? You might be surprised as well, that despite the different paths Dr. Helms and Dr. Israetel took as competitors, that at the heart of their experience lie many similar threads. Join us in this episode as they discuss the spirit of bodybuilding. 00:00 An introducti

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 happen to run into a full blown evidence-based meat head in the wild, be ready for them to start throwing phrases at you at like “muscle protein synthesis”, “leucine trigger”, and “refractory period.” But, times are changing. A recent meta-analysis is casting doubt on the relationship between leucine and muscle protein synthesis in lifters. Now they’re saying leucine is done, saying leucine has no chance. Is that true? Join us in this episode as we do a deep dive on this new paper, what it means, and how to reconcile mechanistic and applied data when they seem to diverge. 00:00 Sexual health (and reading reviews) with

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 the outcome - competitive bodybuilders with PhDs in exercise-related fields who communicate science - their motivations and perspectives are actually quite unique. In this episode, you’ll learn how someone can find themself competing in the wacky sport/art we call bodybuilding, and what that experience can become, in terms of a cathartic outlet, a personal identity, a career, or even a science experiment. The meaning, in something as odd as flexing in posing trunks on stage, can be quite impactful, and quite personal. So tune in to this episode to learn about the personal history of and the meaning found in both Erics

“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 lifters who aren’t too lean - is actually quite normal, how much do you really have to eat? In this episode Omar interviews Eric Helms who just published a study on this very topic with surprising results. Is it really true that eating at maintenance is just as good as a small and large surplus for strength and muscle gain?

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 Trexler being on the last two episodes, while Eric Helms conveniently could not be on at the same time. Well folks, this episode, both Erics are here, and boy do they deliver. Dr. Trexler does a deep dive on the topic of BMI, which has come under substantial fire in recent times due to its shortcomings as a useful clinical metric. But should we abandon it completely? What can BMI tell us? What can’t it tell us? And, how should it be used, if at all, moving forward? And, where do we find the middle ground between advocacy and scientific accuracy? Tune in to find out! 00:00 Introduction to the holy trifecta and Eric’s return

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 larger impact on one's testosterone. Lastly after sharing the not so pleasant realities of dieting and experiencing low testosterone symptoms, Eric shares key points for maintaining a healthy level of testosterone. 00:00 Reading comments: the people know what they like (Eric) Iron Culture Ep. 243- It's Not JUST About Calories (ft.

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, calories out is a little more complicated than most would assume. Made famous by Dr. Herman Pontzer and his book Burn, Dr. Trexler explores what exactly this phrase means, the utility of doubly labelled water and the future of research in this field.   00:00 Officially welcoming Eric (Trexler) to the holy trifecta 06:14 Trexler’s background and what’s in store for Helms Hall 2013 Diet versus exercise in "the biggest loser" weight loss competition https://pubmed-ncbi-nlm-nih-gov/23404767/  Hall 2022 Energy compensation and metabolic adaptation: "The Biggest Loser" study reinterpreted https://pubmed.ncbi.nlm.nih.gov/348166

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 Atwood’s 2021 record of 838.5kg, which importantly, resulted in Taylor beating Austin by 68.5kg. What’s the story behind Austin’s rise, and is he the new pound for pound king of raw, tested powerlifting?

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 on top, as part of an iron thrupple. Tune in to learn about this monumental change in our relationship status. In addition, we recapped some incredible performances at the recent USAPL Mega Nationals, and we also discussed the shifting winds in the social media space from a focus on strength and powerlifting, to bodybuilding.
