Iron Culture presented by MASS

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/34816627/ 18:11 Trexler's training story 29:25 Why Trexler doesn't like Dr Grant Tinsley (scandal) and the passion for exercise science 32:27 Trexler the researcher and exercise energy compensation 39:08 Explaining Doubly Labelled Water 43:28 The overarching aim of Trexler's research and the role of exercise in weight loss Speakman 2019 The International Atomic Energy Agency International Doubly Labelled Water Database: Aims, Scope and Procedures https://pubmed.ncbi.nlm.nih.gov/31743893/ 1:02:40 Negative energy balance and energy expenditure compensation MASS Research Review https://massresearchreview.com/ Willis 2022 Physical Activity and Total Daily Energy Expenditure in Older US Adults: Constrained versus Additive Models https://pubmed.ncbi.nlm.nih.gov/34334719/ 1:13:20 Compensatory mechanisms with negative energy balance Speakman 2020 Why does caloric restriction increase life and healthspan?

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.

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 understanding of what it actually means to blend experience, scientific findings and individual differences together into the art of effective coaching. Join us as we sit down to discuss the topic with one of the most decorated coaches in the game. 00:00 Introduction: the return of Omar Isuf to YouTube Science vs Broscience: What Will Actually Build More Muscle!? https://www.youtube.com/watch?v=zHmceMSIrxg 05:42 Welcoming Cliff (and his polo) back to Iron Culture Iron Culture Ep. 36- How To Look Your Absolute Best: Peaking https://www.youtube.com/watch?v=YShi00QoSTY 12:16 Science vs broscience 19:43 Having an ego and changing your position 24:30 Cliff's communication strategies with clients 36:25 Navigating the psychology of people who compete in physique sport 44:10 Cliff's coaching journey and success 52:02 The evidence-based coach, and anecdotal and scientific evidence 1:13:30 Being wrong, the limitations of science, and retrospective framing 1:17:44 Closing out and driving forward the sport of bodybuilding Where to find Cliff Instagram @cwteamwilson https://www.instagram.com/cwteamwilson/?hl=en Team Wilson https://www.teamwilsonbb.com/ Unrivaled Coaching https://www.unrivaledcoach.com/

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

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 steroid use providing permanent long-term effects…but what if myonuclear domain theory comes under scrutiny? That's exactly where the science is at the moment. As new mechanisms of muscle memory are being explored and the first human data emerges, the picture becomes more complicated. Join us in this fascinating episode as we explore the intersection of muscle physiology, performance-enhancing drug mechanisms, and anti-doping! 00:00 Introduction to an anabolic episode of Iron Culture and Dr Kolliari-Turner Iron Culture Ep. 29- The Science & History of Steroids (And Drug Testing) https://www.youtube.com/watch?app=desktop&v=XN7u4-ckZK8 Kolliari-Turner 2023 An observational human study investigating the effect of anabolic androgenic steroid use on the transcriptome of skeletal muscle and whole blood using RNA-Seq https://pubmed.ncbi.nlm.nih.gov/37138349/ Kolliari-Turner 2021 Analysis of Anti-Doping Rule Violations That Have Impacted Medal Results at the Summer Olympic Games 1968-2012 https://pubmed.ncbi.nlm.nih.gov/33835351/ Kolliari-Turner 2021 Doping practices in international weightlifting: analysis of sanctioned athletes/support personnel from 2008 to 2019 and retesting of samples from the 2008 and 2012 Olympic Games https://pubmed.ncbi.nlm.nih.gov/33415428/ 07:42 Myonuclear permanency Gundersen 2016 Muscle memory and a new cellular model for muscle atrophy and hypertrophy https://pubmed.ncbi.nlm.nih.gov/26792335/ Snijders 2020 The concept of skeletal muscle memory: Evidence from animal and human studies https://pubmed.ncbi.nlm.nih.gov/32175681/ Yu 2020 Potential effects of long-term abuse of anabolic androgen steroids on human skeletal muscle https://pubmed.ncbi.nlm.nih.gov/32343079/ 24:42 Myonuclear domain flexibility?

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 topic in our upcoming issue of The MASS Research Review, and he's here to discuss his conclusions in depth with the CULT. Make sure to tune in, as this information can inform best practices in various situations, as the answer isn't a simple black and white one.

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 and fast fibers convert into one another? How do we measure the fiber composition of muscles? Are fast twitch fibers stronger than slow twitch? Can you produce fiber-type specific hypertrophy? Why are exercise science classes still teaching things about muscle fiber types that were shown to be wrong decades ago? What is on the horizon in this area of research? All of these questions are answered in this highly educational episode! 00:00 Welcoming back Dr Andy Galpin to the Iron Culture Joe Rogan experience and the muscle biopsy procedure 10:14 History of the muscle biopsy 14:03 (re)Introducing Dr Andy Galpin Iron Culture Ep. 20 – The Problem With #Science https://www.youtube.com/watch?v=nHf0QG1Nw_0&t=1s 19:14 The different function of muscles and fiber types 30:50 Fiber type profiling and the methodological limitations 39:21 Science communication and the defensible and indefensible reasons for the perpetuation of muscle fiber myths 52:22 The multinucleated cell and limitations of current research methods 1:09:44 The history of fiber typing and new methods 1:31:46 Practical takeaways for coaches 1:44:15 Andy's coaching philosophy and determinants of performance 1:52:08 Closing out and where to find Andy Website https://www.andygalpin.com/ YouTube https://www.youtube.com/@drandygalpin Instagram @drandygalpin https://www.instagram.com/drandygalpin/?hl=en ResearchGate https://www.researchgate.net/profile/Andrew-Galpin

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 NPC and IFBB that seems to encourage bikini competitors specifically to compete annually, stay lean, and in many cases work with coaching teams with bad reputations. Why does this happen, and what are the consequences?

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 the philosophy it's based on is just as important as Ronnie's story, as it helps us understand the environment where this champion formed. We also had the pleasure and privilege of interviewing Big J, who we are eternally grateful to as he was the one who set up our interview with big Ron. He shared his experiences as the training partner of Ronnie and as a long-time member of Metroflex. You'll learn a lot of interesting things in this episode, like: what was the Texas bodybuilding scene like decades ago? What were Ronnie's early competitive experiences like? Who were Ronnie's inspirations? What was Metroflex like at that time and how did its culture form? You don't want to miss this one if you're a fan of contemporary bodybuilding! 00:00 Yeah buddy!

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 Ronnie Coleman on bodybuilding, and beyond, tune in, because the next episode will be the recap! 00:00 The Road to Ronnie and a rundown of the history of bodybuilding 12:18 The historical context of the Olympia at the time 21:00 The mass monster era 31:19 The impact of Ronnie's reign 44:17 Ronnie's training environment 47:32 Closing out

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 we filming? What exactly are we filming, and what are the future plans for the doc? Tune in to find out and we'll all see you next week, in person, in full!

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 it.

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 powerlifting. Take notice that France tied the US women's team and placed second to the men's team at worlds, something no one predicted just a few years ago. France is definitely on the rise and a key aspect of that growth is the sense of and commitment to community among French powerlifters, that Pana embodies. 00:00 Introducing Pana and his cinematic arc 13:32 Pana's difficult 2022 31:52 Eric's analysis on Pana's potential as a natural bodybuilder 34:45 The growth of Powerlifting in France and the importance of community 1:03:21 The America apology tour and increasing the popularity of Powerlifting 1:11:42 What's next for Pana 1:17:40 Pana's weight and water cuts to make the 66kg weight class 1:26:10 One final question for Pana and closing out Where to find Pana: Instagram @thepanash https://www.instagram.com/thepanash/?hl=en YouTube https://www.youtube.com/channel/UCB1ZlR9h035btvu0t6qFWYg The Panash Training App https://thepanash.app/

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 understanding how volume and effort relate to hypertrophy? Tune in to find out the details that almost everyone talking about this paper, besides the authors themselves, are getting wrong.

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 Worlds on the Olympics YouTube channel while also being televised on Eurosport, are we moving into a new era?

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 the value in staying up with research, and prefer to get continued education from social media. Perhaps unsurprisingly, many of the same coaches also have some shocking misconceptions about female physiology… For more MASS science-based content check out https://massresearchreview.com (en español https://revistamass.com/) 00:00 Welcoming Lauren back as a host of Iron Culture??!! 09:10 Continued education of coaches, trainers, and practitioners Nolan 2023 'There's a perfect way to do things, and there's a real way to do things': Attitudes, beliefs and practices of strength and conditioning coaches in elite international women's rugby union https://journals.sagepub.com/doi/10.1177/17479541231169371 27:37 Barriers to entry and incentivising continued education 56:54 Busting myths vs creating actionable content: evaluating the quality of information 1:07:07 The educational structure in the personal training industry and considerations for your career 1:21:15 Practical applications (education makes you a worse personal trainer!?) 1:34:40 Considering specific and specialised education to improve your practice 1:41:40 Closing statement and where to find Lauren Instagram @laurencs1 https://www.instagram.com/laurencs1/?igshid=NDk5N2NlZjQ= ResearchGate https://www.researchgate.net/profile/Lauren-Colenso-Semple

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 deadlift won't actually improve performance in most sports, or certainly activities of daily living. This leads into a discussion of how gaining strength at a novice or intermediate level may require different efforts and strategies, and may also be due to somewhat different adaptations.

We're back with MASScast episode 2 and we're joined by Dr. Mike Zourdos to discuss several things which can impact your strength performance right now. In this episode we discuss the effect of mental stress on lifting performance, the effect of social media use on lifting performance, and post-activation potentiation, which is a tool where you can potentiate your back off sets' performance with a heavy top set. What constitutes mental stress? How do you minimise the negative effects of mental stress when it can't be avoided? What type of social media usage might be a bad idea before training? How can you set up your top sets in such a way to improve your volume performance in back off sets the most? Join us as we answer all these questions!

Here at Iron Culture we're overjoyed any time the legends of the game are remembered in the current age, and Mike Mentzer, one of the best-built proponents of HIT (High Intensity Training) - low volume, low frequency training to failure - is making a modern resurgence. Is it because he had a top tier golden age physique? Is it the appeal to hard work and masochism that we bodybuilders are always ready to eat up? Or is it the recent research in pre-print status that indicates going to failure might be better for hypertrophy? As you can expect, it's probably a combination of these factors and there's more than meets the eye to each. Join us this week as we go deep into this modern HIT resurgence.

We have an exciting announcement at Iron Culture, we are combining forces with MASS, Monthly Applications in Strength Sport to bring you regular "MASScast" episodes where we will be joined by one or more of the expert MASS reviewers to talk science. In this inaugural MASScast episode we're joined by Dr. Eric Trexler to discuss surprising recent data that suggests basal metabolic rates have been decreasing at the population level over recent decades. Is this true? And if so, what's causing it? In addition, we discuss the continuing confusion regarding high versus low-carb diets. Where is the cut-off for being high or low carb, and when is each a good or bad approach? Listen in to learn what the latest data indicates and how to apply it!

In this episode, we discuss two topics, when and how to address fringe topics in the fitness space and the growing data in support of long muscle length partials for hypertrophy. In the former discussion, we discuss how science communicators are often in a difficult position when addressing such fringe ideas. When these beliefs are believed by small segments of the population - especially if they are potentially harmful - simply addressing them can potentially give them more legitimacy if not done right. Then we dive into "lengthened partials", which only a couple of years ago would have been lumped in with the more common short muscle length partials you roll your eyes at in the gym all the time (think half squats). While formerly a fringe idea, the data continues to elucidate that this approach may have merit for hypertrophy. 00:00 Reviewing reviews: addressing the carnivore diet.

In this episode, we're joined by Mitchell Hooper fresh off his 2023 World's Strongest Man (WSM) win. In addition to winning the 2023 WSM, he also won the 2023 Arnold Strongman Classic. He is among only four competitors to have won these two titles in the same year, and he is the youngest ever to do so, now sitting among living legends Brian Shaw, Žydrūnas Savickas, and Hafþór Júlíus Björnsson. In our conversation we discuss how Mitchell seemingly burst onto the scene out of nowhere, what it's like competing in the WSM, his future, the future of strongman and the WSM in the modern era, and his perspective on being a champion and ambassador. Finally, we discuss how Mitchell's education - having a master's degree in exercise physiology - influenced his training approach, which is surprisingly simple and seemingly non-traditional. As a relative newcomer to the sport, his approach hasn't been influenced by typical strongman "dogma" and thus, his entrance onto the scene may have a revolutionary impact on how athletes train for strongman and strongwoman in the modern era.

You've probably heard of the famous, ancient lifting stones in Iceland and Scotland, some of which are even replicated and used in strongman competitions. But did you know that over 20 stones (and still counting) have been uncovered just in the last few years in Ireland, many of them heavier than the stones in Iceland and Scotland, by primarily one man? That man, Kettlebell Sport World Champion and amateur historian David Keohan (affectionately called "Indiana Stones") joins us in this episode to discuss the incredible stories of how these stones were unearthed. You'll hear about these ancient stones and their rich cultural significance and connections to mythology. While we often think of history as something in the past, when you tune in you'll learn how some history is still being uncovered in real time! 00:00 Paying respects to a ⭐ ⭐ ⭐ ⭐ ⭐ review 3:20 Introducing David Keohan and lifting stones in Ireland Rogue Fitness documentaries Stoneland: https://www.youtube.com/watch?v=MhQlNwxn5oo Fullsterkur: https://www.youtube.com/watch?v=79Tcsg2Yac8 Levantadores: https://www.youtube.com/watch?v=vck32S27RmM 19:53 Researching the stones 32:18 The process of finding the stones and recording the findings 37:24 Promoting the (oral) history of the stones 52:26 Significance of the symbolism of the stones 1:05:45 Closing out and where to find David Instagram: @_indiana_stones_ https://www.instagram.com/_indiana_stones_/

Coaches in the evidence-based community are often up to date with the latest in periodization and sports nutrition, but many are not even aware that there is a tremendous amount of research on coaching itself. What makes a good coach? Hint: it's not simply being up to date with science, as that would mean that every coach prior to the modern era is a bad coach. So, what is it to be a good coach? As the title implies, it's not about you, it's about being athlete-centered. But what does that mean? Join in to find out!

We recently visited Dr. James Steele, Dr. "Pak", and Milo Wolf at Solent University to film some of their research methods and interview them about the innovative, high-quality approaches they take. These guys aren't just any group of muscle nerds though, they are actively working to improve how sports science is conducted, using and promoting the tools of open science. What is open science you ask? Make sure to tune in to learn, as you might be surprised that despite science being the best tool we have to answer life's questions, it has many systemic issues from peer review, to the publishing process, to the reward systems in academia, to the gaps in training that sports scientists often have.

Dr. Conor Heffernan is back to discuss our recent trip to Ireland where he introduced us to Ireland's reigning strongest woman Ayshea Ullah, David Keohan a kettlebell sport world champion dubbed "Indiana Stones", and the many members of Europe's oldest continually open gym Hercules Club, in Dublin. On our trip we learned about the only recently uncovered history of Irish stone lifting that goes back centuries, and got to watch as the current physical culturists of modern Ireland physically connected with the past pioneers of strength, and we also sat down with the old and new members of Herc's in Dublin to learn just how special their community is. Join us in this episode as we reflect on these incredible experiences. 00:00 The fellowship of the stone is back (with a limerick) SBD Road to Sheffield 2023 Series YouTube: https://www.youtube.com/playlist?list=PL85JoAo_KTFuKlOWLRY_-gHj362gYTBOm Instagram: https://www.instagram.com/sbdapparel/reels/ 13:33 The history of the stones that we lifted in Ireland 30:04 The historical and cultural significance of lifting the natural stones 45:22 The origin of Hercules gym and its importance 57:22 Eric and Conor's experiences of training at Hercules gym 1:26:01 Closing out with the unofficial third member of the Iron Culture establishment

Last week was the first time in our history that we left you without an episode, but don't worry this painful experience was for good reason. Omar and Eric were in fact, both together in person, with Dr. Conor Heffernan at the SBD Sheffield. Eric was on stage coaching Jessica Buettner, and Conor and Omar were in the audience filming with the help of the newest member of the fellowship, Jonathan Akagha, the strongest cameraman in Europe. The Sheffield was perhaps the most significant meet in raw tested powerlifting, and for the two days leading up to it, the day of, and the day following, we filmed and interviewed the athletes and hosts to capture the experience. In this episode Omar, Eric and Conor sit down to discuss the Sheffield in retrospect: what was it like behind the scenes as a participant, what was it like in the audience, what did it mean for powerlifting, how will it change the future of the sport, and how will it evolve?

Look no further than the comment section of this post/video and you'll find knee-jerk answers to the question posed in this title driven by emotional reactions, that are justified after the fact by a poorly thought-out argument that is logically inconsistent. In the philosophy of sport, however, you go the opposite direction. You put forth a logically consistent case, based on established information, within the constraints of the argument. In this episode we chat with philosophy Ph.D. candidate at the Berlin School of Mind and Brain Adrian Kind, who recently collaborated on the article: "Is Bodybuilding a Sport?" with Eric. It is currently in peer review, but available as a pre-print for all to read. This philosophy of sport article by Kind and Helms is a rebuttal to another philosophy of sport article by Aranyosi (2018), where Aranyosi claims competitive Bodybuilding is not a sport, but rather an artistic presentation with sport-like elements. While Adrian and Eric didn't prove Bodybuilding is a sport in their paper, they refuted the argument as presented. Tune in to learn about the specifics of this debate, and how a conversation typically reserved for Reddit plays out in academia, and why philosophy is actually at the root of all science. 00:00 Intro to the one (another monster episode) … and introducing Adrian Aranyosi 2017 Body, skill, and look: is bodybuilding a sport? https://link.springer.com/article/10.1007/s11097-017-9513-3 Kind & Helms 2023 Is Bodybuilding a Sport? https://sportrxiv.org/index.php/server/preprint/view/270/539 10:44 Discussing the Aranyosi paper: what makes an "activity", a sport? 26:25 The rebuttal to the takes on posing 41:55 The physical skill component of bodybuilding 1:01:13 The Art vs. Sport spectrum argument Iron Culture Ep. 84- The Original Iron Sport: Gymnastics https://www.youtube.com/watch?v=9_n5AiQvLzQ 1:24:00 Conceding that the physical skill involved in bodybuilding is displaying the body 1:33:40 Why is the categorisation of bodybuilding as a sport perceived as contemptuous? 1:49:03 Do you even lift?

Matt Gary is back on Iron Culture after being on way back in episode 16! This time he discusses nuances most people don't know about game day powerlifting coaching, including even most powerlifters! With the explosion of participants in the sport, there are some weight classes where as many as five individuals could be a world champion depending on how their cards are played. Truly, it's no longer a question of just who is the strongest, but who is the best powerlifter, which requires coaches to truly know "the game". In this episode, one of the most decorated platform coaches in the sport's history, Matt Gary, breaks down what those cards are, all four aces and the joker.

Cult, we've been working on this one for weeks. We've got Desmond Butler on this episode, the lead journalist who wrote the recent Washington Post series on the corruption, exploitation, and health and safety controversies in the NPC/IFBB pro league. We previously discussed this article series both in a duo episode as well as with Dr. Guillermo Escalante, and now, we're privileged to sit down and hear it from the source (or rather the man with the sources). In this episode, you'll learn how Desmond's father directed the cult classic (pun intended) Pumping Iron, and then how years later he'd go on to revisit bodybuilding from a very different perspective. You'll also learn just how much research went into the Post articles, and how many people they spoke to. This was a monster episode for sure folks and an eye-opening exposé.

The boys are reunited, don't worry cult, and yes, reunited atop the pyramid. After catching up on what's been going on for Omar that took him away from us last week, the boys get down to powerlifting talk. This is a big year for powerlifting, with COVID behind us and the Sheffield ahead, and epic battles to come in both the 93 and 76kg divisions at multiple international competitions. Eric discusses how different it can be to coach athletes at the highest level in powerlifting, where scouting, chips, lot numbers, attempt changes, and other subtle aspects of coaching that normally don't come into play, make a big difference as only kilos separate world champions from runner ups. Then, Omar asks Eric about his own competitive aspirations as he's just started his 2023 contest prep, where he plans to go all the way to INBF/WNBF worlds in November, while also competing in his first masters powerlifting meet, as he turns 40 this year.

Dear listener, we just can't let go. Even though we told you in 2023 we wouldn't be able to stick to the weekly schedule, we are trying our best to do so anyway. This week, to maintain our codependent relationship with you, we have a solo episode from Mr. Dr. Eric Helms. Unfortunately, Omar had to travel for Raskol and couldn't join him, but the Cult lives on in a weekly format for a little longer. No, you won't hear Omar say "Eric" to kick things off, no you won't have a half-hour of banter, nor will you hear Omar call this a "monster episode" or find some way to reference Yngwie Malmsteen, but you will get a whole lot of science. In this episode, Eric goes in on the topic of specificity for powerlifting and also covers a new diet break study that was just published. 00:00 An intro to a very different Iron Culture episode… Eric's affiliate link to the NASM Physique and Bodybuilding Coach Specialization https://shop.nasm.org/n/nasmredirecttocart?products=PBC301K%7CCEU164K&coupons=HELMS50 12:12 Topic One: Specificity and Coexisting Principles of Exercise Science Chua 2019 Practice variability promotes an external focus of attention and enhances motor skill learning https://pubmed.ncbi.nlm.nih.gov/30831389/ Williams 2017 Comparison of Periodized and Non-Periodized Resistance Training on Maximal Strength: A Meta-Analysis https://link.springer.com/article/10.1007/s40279-017-0734-y Fonseca 2014 Changes in exercises are more effective than in loading schemes to improve muscle strength https://pubmed.ncbi.nlm.nih.gov/24832974/ Rossi 2018 Strength, body composition, and functional outcomes in the squat versus leg press exercises https://pubmed.ncbi.nlm.nih.gov/27735888/ Lima 2018 Planned Load Reduction Versus Fixed Load: A Strategy to Reduce the Perception of Effort With Similar Improvements in Hypertrophy and Strength https://pubmed.ncbi.nlm.nih.gov/29584518/ Ralston 2017 The Effect of Weekly Set Volume on Strength Gain: A Meta-Analysis https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5684266/ Androulakis-Korakakis 2021 The Minimum Effective Training Dose Required for 1RM Strength in Powerlifters https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8435792/ Iron Culture Ep. 196- How Much Training Do Powerlifters Actually Need To Get Stronger (Ft.

We are joined by Ryan Lapadat on this episode, host of the King of the Lifts podcast, and arguably the best and most prolific powerlifting commentator, despite his relatively recent emergence onto the scene. How did Ryan find himself in the position he's in today, and how has he contributed to the increased interest and popularity in powerlifting that's occurred in the last decade? Ryan will be commentating at the Sheffield next month, and there is a bright future for the legitimization of powerlifting if things continue in the direction they're headed. Join us in this episode as we learn the some aspects of how powerlifting got to be perceived as it is today, the value of narrative in making fans care, and what the future holds for the sport. 00:00 Reviewing reviews with Ryan – Cultural beliefs surrounding women in lifting Iron Culture Ep. 177- Jessica Buettner: 2x IPF World Champion Powerlifter https://www.youtube.com/watch?v=c-M4XAlOa90 Iron Culture Ep. 103- The History Of Women's Bodybuilding https://www.youtube.com/watch?v=uL-2qymV73k Iron Culture Ep. 7- The Rise Of Women In Powerlifting https://www.youtube.com/watch?v=rNd4XCKLcMQ 13:16 Balancing entertainment and knowledge in Ryan's commentary 27:00 Leaning into storylines to bring excitement 43:41 Growth of powerlifting and IPF 50:41 IPF Sheffield 2023 hype up 58:33 Getting "out angled" by Jess Buettner and the revenge 1:06:05 The Masculinity in Crisis Tour and the angle game 1:19:26 The future and growth of powerlifting 1:44:50 An update on Eric's previous Street Fighter tournament SuperLoreBoys YouTube Channel https://www.youtube.com/c/SuperLoreBoys 1:50:06 Closing out and where to find Ryan Instagram: @6packlapadat https://www.instagram.com/6packlapadat/?hl=en and @kingofthelifts https://www.instagram.com/kingofthelifts/?hl=en King of the lifts podcast: https://linktr.ee/KOTL

Stretch-mediated hypertrophy is all the rave at the moment, and much of the enthusiasm is based on a single study out of a specific lab, but, there are actually many other studies that this lab has recently published that give further insights into the topic. Ultimately, what the cult wants to know, is whether stretching-induced gains are complementary or redundant to resistance training-induced gains. In this episode, we discuss not only these possibilities, but also a recent study on SuperCreatine (TM) indicating it might not be so super, but also, that gives us insight as to whether creatine loading is even necessary.

It's episode 208 and yes, you're right, that means it's been four years of episodes coming out weekly, every single . And guess what? In typical iron culture fashion, we completely forgot it was our 4 year anniversary while we recorded this episode. But, dear listener, that's because we were totally focused on YOU, bringing you the latest news in the iron game, from the final Sheffield roster now that the wildcard picks are complete, to the recent USPA controversy, to a new study published on physique contest preparation. Next week, we'll have our belated 4 year anniversary, but this week you get to enjoy another MONSTER episode. 00:00 Intro: what is it?

We were joined by McMaster University PhD. candidate Lauren Colenso-Semple who is studying the influence of exercise, nutrition, and hormones on skeletal muscle, specifically as they relate to the menstrual cycle. She has an extensive background not only in academia, having worked with a veritable "who's who" of exercise science researchers in her journey to her PhD studies, but she also is an experienced personal trainer. In this episode she helps us understand whether "menstrual-cycle phase based training" is truly based on firm evidence, or if in some cases, the popular guidance sometimes extends beyond what we currently know (and what makes sense from a physiological perspective). Make sure to tune in to learn what we do and don't know on this fascinating topic.

If comparison is the thief of joy, then what hope do competitive bodybuilders have for happiness? In a sport where you stand before a panel of strangers who numerically rate your nearly nude body in comparison to others, you'd think it'd be impossible. But is it? What happens to bodybuilders' body image over time? Is it true that whether they place 3rd at the all-valley "championships" or 1st at worlds, they still feel small? If it's not true, why not, to what degree, and in what circumstances? In this episode, we explore whether or not it's true that the day you start lifting is the day you become forever small, and how this mindset can manifest, change, and differ between groups and individuals. 00:00 An update on the Iron Culture documentary and the frequency of episodes 04:50 Self-perception in the social media fitness space Omar's YouTube video will be linked here when it is published! 11:00 Mental and physiological distress in physique athletes Helms 2019 Towards a Sustainable Nutrition Paradigm in Physique Sport: A Narrative Review https://pubmed.ncbi.nlm.nih.gov/31315180/ 19:29 The marketing of bodybuilders and the "desirable" physique 37:21 The motivation to become a bodybuilder and physique (dis)satisfaction Jankauskiene 2007 Muscle size satisfaction and predisposition for a health harmful practice in bodybuilders and recreational gymnasium users https://pubmed.ncbi.nlm.nih.gov/17485962/ 1:00:55 The stressors and influence of the fitness industrial complex Iron Culture Ep. 28- The Problem With The Fitness Industry (with Chip Conrad) https://www.youtube.com/watch?v=o2rtKZ3AnXM 1:17:25 Tethering your expectations to people who can provide you with constructive criticism 1:26:23 Closing out: the internet is terrible but listen to our podcast (on the internet)

After our recent episode with Dr. Guillermo Escalante discussing the potential contributing causes and possibly what could be done about the recent deaths of a number of high profile enhanced bodybuilders, we wanted to follow up. As you recall, this conversation came about because of a Washington Post article series that not only discussed these tragedies, but also exploitation and corruption at the heart of the biggest bodybuilding organization: the NPC/IFBB pro league. Omar made an eye opening YouTube video summarizing these articles, and we discussed them in further depth today, not for controversy's sake, but rather because we both truly want a better future for the sport and art of bodybuilding. In addition, in the latter half of this episode we discussed the challenges of predicting hypertrophy from proxy measures, and where we are at scientifically in this regard, and what it means for practice. 00:00 Revisiting the bodybuilding controversy Iron Culture Ep. 203 Can Enhanced Bodybuilding Be Safer?

It's 2023, and the boys just can't be denied. Four years strong and they've weathered cyber attacks from a bearded AI, fended off an Irish serial killer, and somehow, managed not to get themselves cancelled. In the new year we have big plans, but before we focus on our plans, we want to focus on yours dear listener. First, we know you're still recovering from staying up late for New Year's Eve, and let's be honest, for many of you it wasn't your only late night. How much does getting less sleep than normal impact your training and what can you do about it? After we tackle this practical question, we have an in depth discussion on how to identify the snakes in the garden - the less obvious, shiftier influencers you currently think are helping you, but are just waiting for an opportunity to take advantage of your trust. 00:00 Introduction to a brave new world (and a happy new year!) 14:12 The effect of sleep loss on lifting performance Craven 2022 Effects of Acute Sleep Loss on Physical Performance: A Systematic and Meta-Analytical Review https://pubmed.ncbi.nlm.nih.gov/35708888/ Blumert 2007 The acute effects of twenty-four hours of sleep loss on the performance of national-caliber male collegiate weightlifters https://pubmed.ncbi.nlm.nih.gov/18076267/ Knowles 2022 Sustained Sleep Restriction Reduces Resistance Exercise Quality and Quantity in Females https://pubmed.ncbi.nlm.nih.gov/36136596/ 28:45 Strategies to circumvent acute sleep loss Hsouna 2019 Effect of different nap opportunity durations on short-term maximal performance, attention, feelings, muscle soreness, fatigue, stress and sleep https://pubmed.ncbi.nlm.nih.gov/31491444/ Petit 2014 A 20-min nap in athletes changes subsequent sleep architecture but does not alter physical performances after normal sleep or 5-h phase-advance conditions https://pubmed.ncbi.nlm.nih.gov/24276580/ 45:33 Optimising sleep and training within the given constraints Sargent 2021 How Much Sleep Does an Elite Athlete Need? https://pubmed.ncbi.nlm.nih.gov/34021090/ 59:59 Patterns of behaviour to guide who to follow and avoid 1:10:12 Leveraging trust to sell products 1:30:26 The motivation to create controversial content Stronger By Science: YOUR Drug-Free Muscle And Strength Potential by Greg Nuckols https://www.strongerbyscience.com/your-drug-free-muscle-and-strength-potential-part-1/ 1:41:41 The final takeaway and the masculinity in crisis tour

In a series of recent Washington Post investigative articles about bodybuilding in the NPC/IFBB pro league, Desmond Butler (the son of the producer of Pumping Iron) covered a series of controversial topics. Among them, were the seemingly increasing numbers of competitor deaths. In this episode, we sat down with Dr. Guillermo Escalante, the Assistant Dean and a Professor of Kinesiology in the College of Natural Sciences at CSU San Bernardino, who is a competitive bodybuilder himself, as well as an athletic trainer (a sports medicine first responder). He was interviewed for these Washington Post articles because from 2012 to 2019 he spent many of his Saturdays in Southern California at shows, making himself available in case any athletes had medical emergencies. Dr. Escalante has also specifically published research examining the potential causes of death of enhanced pro bodybuilders. Needless to say, there are few people with more direct knowledge, experience, and perspective on the potential dangers of certain practices in enhanced physique sport, whether these risks can be reduced, and how.

Mr. Benjamin Franklin Esgro has the unique honor of being our first guest in our episodes numbered in the 200's, as well as being on for his fifth, or maybe sixth time? We aren't sure, but we like to have the man on! I'm this episode, he's once again crusading against potential charlatans in the supplement industry. If you remember last time, Ben joined us to discuss the lacking evidence of a mechanism of action behind turkesterone and today, he's back to give us a dose of reality on paraxanthine. What is paraxanthine you might ask? Well if you haven't already heard of it, it's supposedly the next big thing in the stimulant, nootropic and pre workout world. But, while this supplement is interesting and may have specific utility, should we really expect something truly groundbreaking considering it's a metabolite of caffeine?

It's the start of a new era, as Omar and Eric sit down for episode 201. In this conversation, the two pick up where they left off from episode 200, tackling the Cult's questions that were too good, and too deep to cover last week. Specifically, we discuss how to compare the potential effects of dissimilar variables on hypertrophy, such as sleep, protein, and creatine using research. Further, we field questions on how you measure progress and deal with plateaus, and whether higher frequency training can provide unique advantages. 00:00 Introduction to a new era of Iron Culture (and reading comments) 15:11 Start of Q&A.

We can't believe it. 200 episodes. What else is there to say except thank you from the bottom of our hearts? It's always a blast for us to hang out and chat, but it's a huge bonus that so many people find value in our conversations. At the outset, we hoped we'd be able to provide both educational and entertainment value to our listeners, and it seems like we've succeeded. This episode is a bit of a celebration, as we reflect on what brought us here, and what it's going to lead to. We have big plans dear listener, and I think you're going to like them. Also, we squeeze in a little bit of genuine Q&A from the cult (we promise we didn't make these questions up, seriously). 00:00 Intro: history of THE Iron Culture 3:12 🚨🔥Episode 200 🔥🚨 and a HUGE news reveal 16:25 The Helms review of the 2022 IPF Commonwealth Championships 31:30 The importance of the Sheffield Powerlifting Championships 44:15 What is Eric competing in next year?

While technically correct, saying "protein is the most satiating macro" misses the point. We don't actually eat macros, we eat foods that have a macronutrient profile, and two diets identical in their macronutrient profile may differ in their effects on hunger and satiety. In prior episodes, we've discussed protein in depth, but this is the first time we've had an in-depth discussion on how protein influences satiety. Further, we address misconceptions about fat gain on high-protein diets and the impact of high-protein diets on energy expenditure. Ultimately you'll learn that when considering satiety, macros, foods, meals, and diets all need to be considered in context for an accurate picture. 00:00 Intro and reviewing reviews: social media fitness edition Iron Culture Ep. 20- The Problem With #Science https://www.youtube.com/watch?v=nHf0QG1Nw_0 Iron Culture Ep. 182 - How to call out B.S. and Pseudoscience https://www.youtube.com/watch?v=ckzuycwnRH8 Iron Culture Ep. 93- What's Wrong With The Fitness Industry (And How To Change It) https://www.youtube.com/watch?v=tWYABSS9FlE Cyber Monday Sales The Muscle and Strength Pyramidshttps://muscleandstrengthpyramids.com/ MASS Research Review https://www.strongerbyscience.com/mass/ Elemental Formulations Prime Pre-workout https://eformulations.co/products/prime-pre-x-high-stim-pre-workout 13:50 Eric's recap of WNBF Worlds and the typical age of high-level competitors Iron Culture Ep. 27- Natural Bodybuilding https://www.youtube.com/watch?v=m0AEvN2L9zU Solberg 2019 Peak Age and Performance Progression in World-Class Weightlifting and Powerlifting Athletes https://pubmed.ncbi.nlm.nih.gov/30958059/ 26:40 Is protein the most satiating macronutrient?

For many, research is taken to represent a framework for understanding concepts that can then be applied to their own training. This can be taken too far when some hope to divine exact details that apply specifically to their own journey. Research isn't meant to tell you (dear listener) how to train on a Tuesday. What is the best way to properly utilize the current literature to better our own lifting journeys?

In this episode we are excited to revisit an ever-controversial topic in bodybuilding, training to failure! Yes, we've discussed this before on Iron Culture, and yes, people have surprisingly (but maybe not so much when you dissect it…) strong feelings about training to failure. You may remember that one of the biggest limitations in the literature we previously discussed in our last episode was that there are different ways of defining failure. Should we be lumping together studies that use "momentary muscular failure" with studies that used "repetition maximums" or "voluntary failure"? Probably not. But great news, Martin Refalo a Ph.D. candidate at Deakin University specifically studying the effect of failure on hypertrophy joins us in this episode. Martin recently published a scoping review and a subsequent meta-analysis that specifically identified these differences in failure types and analyzed the literature based on these distinctions, as well as looking at velocity loss thresholds to provide new and important insights on this topic! Tune in to learn more!

We are delighted to have Dr Patroklos Androulakis-Korakakis on Iron Culture! "Dr. Pak" is a researcher and lecturer at Solent University, coach at stronger by science, and finally, a lifting enthusiast himself. He did his PhD on powerlifting. Specifically, he conducted research to answer the question: "how much training do powerlifters need to do, to make meaningful increases in strength?" This question led him to conduct interviews and surveys with the best powerlifters and powerlifting coaches in the world to first understand what they consider "meaningful" strength gains to be, and then he conducted some of the very few longitudinal training studies on competing powerlifters to determine just how much work they need to do to get better. Join us in this fascinating look at the inner workings of his research, as well as some of the more recent research he's currently involved with, bridging the gaps in terminology and application between science and practice.

"Should I cut my calories back during deloads?" This incredibly common question pops up all the time online, and there are a few things to consider when answering it. First, the purpose of a deload, technically, is to recover after an overreaching phase. What do we expect after an overreaching phase? Are these expectations compatible with a reduction in calories? Secondly, we need to consider the differences in total energy expenditure between a deload week, and the preceding training, which again, consisted of an overreaching phase. Finally, in this episode, we discuss other cases, for example "deloads" that don't occur after overreaching, deloads following strength/intensity-based overreaching, tapers, and intro weeks. While the question is simple, the answer has a bit of nuance, so join us to learn these details! 00:00 Intro: addressing the "alliance" with Stronger ByScience 12:07 Eric's damage control apology and appeal to the Iron Culture HR department 17:05 The effects of deloads on muscle hypertrophy: should you cut calories on a deload?
