Iron Culture

How do we know what we know? And do we know what we think we know? If your answer is “I don’t know,” then this episode is for you. In this classic-style episode, Omar and Helms sit down for a spirited chat on epistemology: the theory of knowledge, as it relates to hypertrophy. In the “evidence-based” world some people always claim to have things figured out entirely. In the case of hypertrophy, some people currently can explain with a “model” what must occur in training to produce hypertrophy, in a logically consistent narrative, based in true aspects of physiology. However, just because something is logically consistent and contains elements of truth, doesn’t necessarily make it entirely correct. So first, we should ask, when and why should models be used in scientific inquiry? How do models sit in relation to empirical studies? How does one check the veracity of a model? Is a “model” really a model if nothing was actually modelled? Can it be valid if it is contradicted by dozens of controlled trials? Most i

Research moves slow, well, at least slower than we wish it did. But, that doesn’t mean it doesn’t also produce paradigm shifts that shake up practice. In this episode Dr. Helms and Dr. Trexler sit down to answer questions using research, most of which that is actually still in the publication process and not yet available. This research will have a major impact on the future of practice in nutrition, as it relates to protein while dieting, training, as it relates to how much volume lifters perform, and cardio, for both training and health.

In this Iron Culture episode Dr. Helms sits down with fellow 3DMJ coaches and Iron Culture veterans Brian Minor and Alberto Nunez for a spirited debate about who they each think are the top 5 natural male bodybuilders of all time. Bodybuilding is where art and culture meet science, where science meets sport, and if you are a fan of natural bodybuilding and its history, you will love this episode. Listen in as they struggle to even agree on a criteria for someone to be The Natty GOAT, learn little-known facts about the early years of Kai Greene’s career when he was natural, and pay careful attention to the honourable mentions, as there are many potential candidates, for the “Mt. Rushmore plus one” of natty competitive bodybuilding. 00:00 Welcome to an exciting episode without Omar and Trexler 02:29 Brian and Berto’s history with bodybuilding Iron Culture Ep. 26- How Progressive Overload Actually Works https://www.youtube.com/watch?v=sfe8tsxFieI&t=37s 10:20 A debate of the Mt Rushmore + 1 of natural bodybui

Caffeine is incredibly popular among lifters and non-lifters alike. In a variety of cultures all across the globe (including the iron culture), caffeine is a daily staple. While most people use caffeine for a morning boost of energy, lifters have long used caffeine as a performance-enhancing supplement. There is a tremendous amount of evidence reporting acute ergogenic effects from a single dose of caffeine, but there is a surprising lack of research addressing critical questions about caffeine's utility as an "everyday" pre-workout supplement. In today's episode, Eric Trexler reviews a new study suggesting that caffeine improves performance when consumed in the morning, but not in the evening. This is followed by an in-depth discussion about when caffeine may (or may not) be effectively used as a performance-enhancing supplement, and how to balance potential tradeoffs between acute performance enhancement and sleep disruption.

This week 2x 66kg IPF Open World Champion Panagiotis “Pana” Tarinidis joins Eric Helms on Iron Culture to discuss the state of modern powerlifting. The two of them recently joined legends, phenoms, leaders and top thinkers of the sport like John Haack, Greg Nuckols, Lya Bavoil and others at the 2024 European Powerlifting Conference in Limerick Ireland. The existence of such events is emblematic of powerlifting’s growth, but so too is just how competitive IPF powerlifting has become. At 2024 IPF Worlds the podium for the 66kg class was decided by bodyweight, as all three men had identical totals. In this interview Pana shares what it takes to stay in the fight in modern powerlifting, how hard it is to vie for a championship title when the competition is so tight, and the mindset, passion, and focus it requires. 00:00 Intro with the “new Omar” and a recap of the European Powerlifting Conference 09:03 The lifting stones 18:20 Goals and learning from meaningful achievements – Pana’s recent IPF World’s experience

The classic Iron Culture duo hosts this week’s episode to discuss exercise variety. How have the views on this topic changed over the years and why? First, we need to understand how and when bodybuilding separated from strength sport, equipment availability changes over time, and how these factors impacted the perception of exercise variety. From the Weider “Muscle Confusion Principle” to motor learning concepts like varied practice, there’s been discussion of exercise variety in both the trenches and research for decades. In the modern era, concepts like regional hypertrophy and more nuanced understanding of functional anatomy have become more common and widely understood and accepted, leading to the acceptance that at least for hypertrophy, higher exercise variety is necessary to maximise the development of specific muscle groups. But, as they say, a little knowledge is a dangerous thing. Many without a sufficiently complete understanding of anatomy make errors when it comes to claims about exercise selecti

The Erics are back, and this time, they work through a mental model of how training volume, or rather, the training dose changes over time. With a rank novice, a single set to failure done once per week will typically produce continued adaptation, and they won’t plateau for 1-2 years! However, if you take an advanced strength athlete or bodybuilder, a single set to failure done once per week seems to not only be insufficient for measurable progress to occur, but is even lower than doses that result in small losses of muscle mass. So, it seems the that the minimum effective dose of training changes as one reaches higher levels of training status. But does this mean volume needs increase with training status? Not exactly, but that depends on how you define “needs.” There is an interaction of these concepts with the minimum detectable change we can notice, our goals, the timeline we wish to achieve them in, and also the slowing rate of progress that naturally occurs as one gets closer to their potential. Can the

The trio is back to discuss a classic Iron Culture topic: how much does increasing muscle mass contribute to strength? But, before we can answer how much, we must acknowledge that some in the scientific community doubt whether hypertrophy contributes to strength at all! What is the source of this skepticism and how do we resolve this debate? Tune in to learn not only how getting jacked impacts strength, but also the importance of study design, what is needed to make causal inferences, and how to make conclusions in the absence of ideal data. 00:00 Reviewing reviews (and adding a missing reference) Cook 2019 Body Mass and Femur Length Are Inversely Related to Repetitions Performed in the Back Squat in Well-Trained Lifters https://pubmed.ncbi.nlm.nih.gov/30640306/ MASS Research Reviews https://massresearchreview.com/ 16:29 End of the extended banter and into the topic (getting into some research design) 24:25 Breaking down the first study and correlated changes Tromaras 2024 Lean Body Mass, Muscle Architecture

PhD candidate Ryan Anthony joins the Erics on Iron Culture to discuss the fishy business of Omega-3 supplementation. Ryan is in the final years of his PhD research at the University of Wollongong in Australia, investigating the role of omega-3 fatty acids in reducing muscle fatigue and soreness following exercise. His research has identified consistent methodological issues in many of the studies on the topic, which may explain why omega-3 data has become more mixed in recent years. In this episode you’ll learn exactly what omega-3 fatty acids are, how they function in the body, the difference between EPA and DHA and the relevance of their differences, if it is worth supplementing with omega-3s, and whether most supplements on the market are actually properly formulated to provide the potential positive impact sometimes observed in research. 00:00 It’s the tag team Eric duo with an introduction to fish oil supplementation 03:08 Introducing our guest Ryan, his research, and Omega-3s 11:57 Fish oil trials, biom

Walter Cariazo joins Omar and Eric Helms on Iron Culture to discuss his decade-long journey in powerlifting. He’s won the 93kg National Championship twice and the 105kg National Championship once in Canada and has had the opportunity to represent Canada twice at the IPF World Championship, most recently in Lithuania in June. In this most recent competition, he was a dark horse for the podium, as he placed 4th in the 105kg class, getting the opportunity to pull for the bronze medal position, which would have secured him a spot in the first World Games in 2025 to include the raw division. While this in and of itself is worth highlighting, most impressively, Walter has continually progressed in his decade in the sport, despite a busy, demanding work and life schedule. He is a full-time medical radiation technologist, in addition to working as a videographer (you may have seen him on Omar’s YouTube channel) and photographer. The perennial lifelong lifter, Walter embodies the spirit of iron culture as a “blue-coll

A long lifting career comes with plenty of ups and downs, so we’re accustomed to hearing stories about setbacks, comebacks, and perseverance from our favorite lifters. These setbacks can take many forms, but Jared Maynard’s extraordinary story exists in a league of its own. Over the course of a few short weeks, a rare autoimmune disease took Jared from being a young, strong, healthy man in his early 30s to being on life support in the intensive care unit. With survival odds worse than the flip of a coin, Jared fought his way out of the ICU and started training right away. The major difference is that his training program involved re-learning how to eat, sit up, and roll over before he could focus on squat, bench, and deadlift. Barely more than one year removed from life support, Jared was back on the powerlifting platform setting PRs and deadlifting over 500lbs. In this episode, Jared shares his incredible story with Omar and Dr. Trexler, and talks about how years of lifting likely saved his life and set him

The most dynamic Iron Culture duo is back in action. In this episode, Omar and Dr. Trexler talk all about pain, injury, and factors that impact the relationship between them. Back in the day, most lifters were all-in on the “Cartesian” or “biomedical” model of pain, which posits that pain is a simple, reliable indicator of damaged tissue causing nociceptors to send a “pain signal” to the brain. Nowadays, the “biopsychosocial” and “fear-avoidance” models are all the rage in the evidence-based lifter circles. These models are a major upgrade, but there are still some pervasive misunderstandings and misinterpretations of these models in the lifting world. In this episode, Omar and Dr. Trexler try to provide some clarity on the matter using research, anecdote, and a decade-old textbook on Dr. Trexler’s bookshelf.

The trio is back, and this time to discuss the science of saturated fat. For decades, saturated fat was widely blamed for a dramatic rise in rates of obesity and heart disease. In recent years, that narrative has been challenged by proponents of increasingly popular ketogenic and carnivorous diets. For many, the back and forth on this topic is dizzying, and confusing. Fortunately, we have Dr. Trexler to walk us through several recent studies to help determine if saturated fat is actually inherently more fattening than other fat sources, either via its impact on energy expenditure or appetite, and then how it plays out in the real world, and finally, to discuss what you need to know, and what - if anything - you should change about your diet.

When people think of “good coaching” in the evidence-based community their first thoughts are often related to whether or not the coach is up to date with the science and whether they use pseudoscience in practice. So does that mean that every coach from the 1990s and prior was a bad coach? Is good coaching actually determined by the methods you use, or something else? Can you be a bad coach while also being up to date with science? In this classic duo episode, Omar and Eric dive into the key qualities they think good coaches possess, and explain why the methods you use are not the same as the skills of delivering, implementing, adapting, and communicating them or the motivations behind your efforts to do so.

One of the most common recommendations a personal trainer or dietitian might make to someone embarking on a weight loss journey, is to drink more water. It’s a basic behavioural recommendation, like going on walks, eating more fruit, vegetables and lean protein, adopting a consistent sleep schedule, and engaging in regular exercise; all solid recommendations. Being hydrated is certainly important for health, wellbeing and performance, but is there actually evidence that drinking water will aid weight loss? Tune into this deep dive by Dr Trexler as he breaks it down and explains why drinking more water is great advice, but probably not for the reasons you think. 00:00 Please send us your sugar-alcohol protein bars 08:29 A segue to the topic: some alternatives to sugar-alcohols and what do if you catch Trexler eating a bunch of protein bars MASS Research Review https://massresearchreview.com/  14:21 The throwaway line: drink water to lose weight Chen 2024 Water Intake and Adiposity Outcomes among Overweight and

Powerlifters use techniques to milk every last kilo out of their bench press, including wide grips, tightly wound wrist wraps, leg drive, and – the most hated technique in the comment section – an arched-back to reduce the range of motion. Indeed, it can get so heated in the comments it likely even influenced an IPF rule change last year. But how many kilos does an arch really give you? How many bench pressers did this rule change impact, and was there really a need for the rule changes? Further, why do we apply a different standard for what is considered “cheating” to different lifts or athletic movements, like technical manipulation in high jump, or weightlifting? In this episode you’ll get the full complement of the Iron Culture themes: we discuss the current culture around the IPF rule change and contemporary perspectives on arched bench press, the history of the clean and press in Olympic weightlifting up to 1972 which has some very interesting parallels, and finally a recently published study which atte

Fresh off of their successful doctoral defenses, Lauren and Kim join Iron Culture to discuss all things menstrual-cycle related for lifters! Dr. Helms had the pleasure of mentoring Kim, who recently completed her PhD at AUT, in which she surveyed and monitored the menstrual cycle symptoms of resistance-training women, and also led an intervention of mindfulness-based yoga to see the impact on menstrual cycle symptom severity. These findings are complemented by Lauren’s PhD research, recently completed at Stu Phillips lab at McMaster University, where she looked at muscle protein fractional responses to resistance training in women during different menstrual cycle phases. Covering both the applied and mechanistic side of the equation, this Roundtable discussion led by the Erics gives you the cutting-edge low down on whether or not menstrual cycle phased based training is all that it’s hyped up to be.

We’re back with another trio episode, and in this one, the hosts dig deeper into the Trex-lore. Eric Trexler has been training since his early youth, but only recently has he struggled with his fitness, and health and even had to rethink who he is as a lifter, due to lingering pain. Pain and injury are complex and multifaceted, but the body is resilient and often heals itself with time. But what can you do when nothing seems to work? When you seemingly can’t change your circumstances the only thing left is to change your perspective. Join us in this episode as the hosts share these perspectives, with a collective experience of over 50 years under the bar.

To complement the recent appearance of Dr. Wes Goodman, we now have the founder of N1 Education, Coach Kassem Hanson to join us on iron culture to discuss applied biomechanics and anatomy for bodybuilding. We discuss the limitations of research, what might be considered fundamental features of effective hypertrophy exercises, common mistakes and misunderstandings of applied anatomy, individual differences and more! Join us in this discussion of bodybuilding functional anatomy and learn how to take your, or your clients training that much closer to optimal. 00:00 The Erics introduce Kassem and the topic Iron Culture Ep. 273- Biomechanics For Powerlifting https://www.youtube.com/watch?v=BB6_fIlx8EA 05:09 Why and how Kassem is ruining resistance training for the youth 10:43 Kassem’s background and what he does 19:00 What the technology is actually measuring and their limitations 27:13 Exercise selection principles 40:43 Working around structural limitations and injuries 47:27 Getting into the weeds of exercise s

Since the beginning of the iron game, different methods have been promoted as the best approach to train for “hardgainers.” Likewise, in the scientific literature, the variability in individual response is well documented, including the identification of “non-responders” and poor responders to exercise. However, only recently have studies been undertaken to determine how to manipulate training to help poor responders to resistance training get better gains. So, is it true what they say? Does “hard work beat talent when talent doesn’t work hard”? And if so, what type of “hard work” needs to be done exactly? 00:00 Introduction to a duo episode with two of the best Erics in the fitness industry and the history of the "hardgainer” 09:48 “Non-responders” in the literature and measurement error 17:27 Individual vs group level responses 25:32 Challenging the idea of non-response to training Montero 2017 Refuting the myth of non-response to exercise training: 'non-responders' do respond to higher dose of training htt
