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 unprecede...

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, bu...

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 Wor...

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 ...

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 ...

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 p...

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 sea...

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 throw...

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 -...

"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 epi...

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. We...

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 an...

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 h...

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'...

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 relations...

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 necessarily a win for #science, if anything, it's a wake up call for people to have a better understa...

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 a...

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 domain theory. Our understanding of the mechanisms of "muscle memory" leads to the possibility of anabolic...

The MASScast Iron Culture episodes are back! Today Dr. Eric Trexler joins us to answer the murky question: "What is an evidence-based guideline for a minimum dietary fat intake?" It's easy to find guidelines and minimums for various circumstances and goals for protein, and while there is some debate, the same could be said for carbohydrate. However, a minimum intake for fat has been elusive. Fortunately, Dr. Trexler has been thinking deeply about this topic and wrote an extensive article on the ...

Dr. Andy Galpin, world leading muscle fiber researcher, is back on Iron Culture! Dr. Galpin is not only a researcher, but a sports scientist and coach working with some of the most prominent elite athletes in the world, and an excellent science communicator. So, it was a privilege to have him on to talk Muscle fiber typing; because everyone talks about it, but very few people get it right when they do. Should you train differently if you're predominantly a fast or slow twitch lifter? Can slow an...

Laurin Conlin is back on Iron Culture after a long hiatus! For those who missed her first appearance, Laurin Conlin, MS is a coach and high-level competitor, having competed as an IFBB Pro Bikini athlete from 2014-2018. She recently visited Eric before they flew to Melbourne to present at the annual Ultimate Evidence Based Conference at JPS Health & Fitness. In her and Eric's conversations in and around the event, they discussed "the competitor trap"; the unique atmosphere and culture in the...

Last week we dropped the bombshell that we were going to have the opportunity to interview icon and 8x Mr. Olympia Ronnie Coleman, this week, we recap how it went. This episode was recorded while we were still in Texas, after returning to Austin following our road trip to the original Metroflex in Arlington. We not only got to interview Ronnie while there but also Brian Dobson, the founder of Metroflex and the man who shepherded Ronnie into competitive bodybuilding. The story of Metroflex and th...

Yup, it's confirmed. We're going to interview living legend, 8-time Mr. Olympia Ronnie Coleman at the one and only Metroflex in Arlington Texas, in person, along with its founder Brian Dobson, and long-time training partner of The King, Big J. This is huge news and a big part of our Iron Culture documentary filming in Texas. Eric, Omar, and Conor recorded this episode just days before heading to Metroflex after confirmation of the interview. They discuss the cultural and historical impact of Ron...

With both hosts traveling to Texas, this is one of the rare weeks in which you get only Eric. Even more tragic (or perhaps a relief), you only get him for 10 minutes. But, it's an exciting 10 minutes as you'll learn exactly why the duo is headed to Texas: to from the holy hunk trinity by meeting up with Dr. Conor Heffernan for the second filming location of the Iron Culture Documentary. We'll be there with cameraman and audio editor extraordinaire Brandon Wells, to do it live. Where exactly are ...

In this MASScast episode Dr. Helms shares his recent experience cutting down to and competing in the 83kg category - a weight class lower than his typical - in the midst of his bodybuilding contest prep, and how he maintained the vast majority of strength from the start to the finish of this process. Then, he does a deep dive on the topic of muscle fiber-type specific hypertrophy, with a focus on a new systematic review that asked the question of whether blood flow restriction training can cause...

We are joined by Panagiotis "Pana" Tarinidis, the now two-time 66kg IPF unequipped World Champion fresh off his win at the 2023 world championships in Malta. His story is one of redemption, as despite winning Worlds in 2021, he placed 5th at Worlds last year, and bombed out of the European Championship in November. But more importantly, we learn what fuels Pana, his connection with his father, what this win meant to him and his family, and how important community is for a growing sport like powe...

In this MASScast episode, we're joined not only by MASScast fellow host Dr. Mike Zourdos but also Ph.D. candidate Zac Robinson of Data Driven Strength, both of whom are co-authors on a pre-print that is making a lot of waves in the evidence-based community. Their series of meta-regressions has shown that perhaps the impact of failure is more substantial than previously believed, at least for hypertrophy. But is it that simple? Also, is this paper a "game changer" when it comes to the understandi...

With Eric freshly back from coaching and commentating (how dare he) at IPF Classic Worlds 2023 - the largest, most competitive worlds to date - it only makes sense for a recap and discussion regarding the state of powerlifting. How have things changed after the recent Sheffield? Are the champions of today different than the champions of the past? How are things like judging changing with the advent of video replay, and how has the growth of powerlifting impacted the sport? With live-streaming of...

Let's face it, going to school isn't cheap. Moreso, you can learn almost anything online that you can learn in school. So is it worth it? How about for personal trainers? If it is worth it, for who and when? We're joined on MASScast 3 by Lauren Colenso-Semple who is nearly finished with her PhD. Not only does she share her valuable perspective, but she also reviews some interesting new research on women's rugby coaches, many of whom - despite holding a bachelor's or master's degree - don't see t...

Patroklos Androulakis-Korakakis, AKA "Dr. Pak", is back! In this episode we caught up with Dr. Pak while he was visiting Omar's home turf in Toronto! There they trained together, and after a crappy training session where they failed PR attempts, they decided to have a completely unrelated episode on why strength is overrated. No, but seriously folks, this is a great discussion of specificity and transfer of strength. We discuss research that suggests maybe going from a 300lbs to a 400 or 500lbs ...
