Episodit

  • 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.

  • 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 attempted to quantify how much an arch increases bench press 1RM.

  • 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.

  • 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?

  • Wes Goodman recently completed his PhD in Exercise and Nutrition Science with an emphasis in Biomechanics and Motor Control at Montana State University under Dr. David Graham with our very own Dr. Helms on his committee as well. But he’s more than an academic, he’s a certified strength and conditioning specialist, gym owner, power lifter, strong man and Highland Games competitor! He studied how musculoskeletal modelling can help us understand the nuances of how the body performs squats. In this episode you’ll learn about the theory and application of motor control to lifting, the limitations of common biomechanics studies, and how modelling helps us understand that muscles can influence joints they don’t actually cross, and to Omar’s dismay, that a calf raise might actually be a squat accessory exercise!

  • We here at Iron Culture have been on a mission to better inform you, dear listener, as to the inner workings of science. From what goes on in the lab itself, to the publication process, to dissemination, to eventual meta-analysis, the challenge of interpretation and communication of science, the optimistic promises of open science, and the increasing focus on replication, it’s been a hopefully eye-opening and overall encouraging discussion. However, while the scientific method is inherently self-correcting, the apparatus of science is far from perfect and there is a big problem with its principle tool of correcting the peer-reviewed record: retraction. What leads to a paper being retracted? What is the process? How does it impact the literature? Most importantly, does it effectively change the understanding of the science in the community the studies are meant to serve? Join the Erics in this most recent episode as they break it all down!

  • Whitney Houston said it best: “I believe the children are our future, teach them well and let them lead the way.” Here at Iron Culture, we’re old, irrelevant and out of touch. But, we believe in platforming the next generation of educators to carry on the torch (or at least pandering so they’ll platform us in return when we can no longer pay the bills). In this Roundtable we’re joined by Dr. Milo Wolf, Dr. Pak, and first-time guest Max Coleman, to discuss the challenges of growing a following using social media in 2024 as an evidence-based content creator. The game has changed what worked for us, won’t be as successful, and striking the right balance is not easy, and getting it wrong comes with lashback. Are we all just doing more harm than good?

  • Dr. Pak is back on Iron Culture for his third appearance! This time, he sat down with Omar and Dr. Helms for a meta-discussion on the challenges of science communication. How do you maintain credibility when you’re using social media as a science communication tool? This challenge has changed, but it isn’t new by any means. The “Sagan effect” describes the well-researched phenomenon by which the scientific community perceives other scientists who get more media exposure as less legitimate scientists - despite the fact that, on average, scientists more active in science communication typically publish slightly more often and with a higher impact than scientists less active in science communication. In modern times, however, the incentive structures are different, and many instances of expert creep, “selling out” and pseudoscience have been propagated on social media by some academics or members of the medical community. In this episode we discuss the challenges of attempting to communicate science without being criticized for doing so, how this has and hasn’t changed over time, and the instances of gatekeeping which are ultimately counterproductive to increasing scientific literacy.

  • The holy trinity is back and holy smokes do we have a Holy Ghost of an episode! First, to kick things off the crew discusses the recent “March madness” of powerlifting that just finished: IPF European Champs, the UK Arnold, and Powerlifting America Nationals. Some absolutely stunning performances occurred all over the world in powerlifting and it seems the rising tide of talent has no end. Then we get into the meat - or should I say the bottomless soup - of the episode. While fraud in research is exceedingly rare, it does happen, and unfortunately, more common issues such as p-hacking are a far more prevalent issue. What is to be done in situations like this? One tool, as the Erics discuss, is replication.

  • After their recent reconciliation, the Erics got together for this duo episode to bond over their mutual love of protein. But, dear listener, this might not be the home-cooked high-protein meal you hoped for. Dr. Trexler tackles the question of whether or not, GASP, protein restriction might extend lifespan! Then, to add insult to injury, the Erics dig into the question of whether or not plant-based protein sources could be superior to animal sources for improving healthy aging! Along the way, you’ll also learn about the limitations of both epidemiological and mechanistic protein research, and how the two can complement each other to lead to more robust conclusions. So grab your pea protein shakes - or maybe your protein-free placebo - and tune in for another monster episode of Iron Culture.

  • As you know, Iron Culture reps the neutral to positive gang around these parts. While most new supplements released to the market don’t pan out as effective, some do. So, if preliminary data supports the potential efficacy of a new supplement, why not try it out? The only potential downside of trying a new supplement is wasted money, right? Not so fast. In this episode the Erics duo explains why the typical supplement consumer is not accurately weighing the true potential cost of supplement investment. Unbelievably, some data indicates 10-30% of all supplements are contaminated - you heard that right. Could that be true? If so, why and how is this happening and what can you do about it?

  • Evidence-based practice has unfortunately become a meme, and its meaning, role, and utility are less understood than they were just a handful of years ago. In this episode we dive deep, discussing how to incorporate study findings into practice. If you don’t have the ability to gauge the impact of a study’s findings, how do you stay up to date? We answer critical questions like: How does the hierarchy of evidence operate in a field where many meta-analyses have errors? What is the role of mechanistic research compared to applied research, and when should you look to each to inform what you do in the trenches? At a time when many seem ready to simply throw in the towel on the evidence - despite it actually being of a higher quality, than it ever has been, we are here. We are going to bring you back from the brink so that you can make those sweet, sweet evidence-based gains.

    1:41:32 The final thoughts and a teaser for next time

  • It's time for a MONSTER episode about protein. Naturally, Helms has recused himself because of his heavy biases and conflicts of interest with the shadowy figures behind Big Protein. As a result, Trex and Omar take a trip down memory lane and discuss everything we used to know about protein, and how a surprising percentage of that knowledge has changed over the last decade or so of research.

    It wouldn't be fair to say that everything you thought you knew about protein is wrong, but there's no question that evidence-based protein guidelines have been significantly impacted by some paradigm-shifting studies that have occurred in the last few years. In this episode, Trex and Omar discuss what these new studies have taught us about protein, and how we can put this new information into action.
