In this Iron Culture, Sigma Nutrition Radio, SNA crossover, Dr. Joe Klemczewski returns! Dr. Joe, possibly the first online bodybuilding coach and person to advise clients to track macros before IIFYM was an acronym, joins us to reflect on the past and help us navigate the future. In the modern information age, there is more information than ever, which is a good thing, right? Perhaps, except that there is also more misinformation and disinformation than ever as well. While the evidence-based movement solved the problem of information inadequacy, we now face a much more complex problem of information illiteracy. What can you do to better navigate the âfake newsâ littering all aspects of social media, especially the nutrition space, and how can you facilitate better critical thinking in your clients and followers to reduce the likelihood they will undertake harmful diets? In this episode we tackle just that, discussing how paying attention to history and social changes can provide protection against modern fads.

Even among the many monster episodes of Iron Culture, todayâs episode truly stands out. First, the MASS crew discusses this new era of Iron Culture and lets the cult know what they can expect as the show pushes forward and climbs to new heights. After that, the crew has an insightful discussion about the science of satellite cells â what they are, when they might (or might not) matter, and how they intersect with many hypertrophy-related topics, such as sex differences, aging, muscle damage, and factors that limit long-term muscle growth.
The MASS crew records Iron Culture LIVE on YouTube, every Monday night at 7pm eastern time. Be sure to join us for a future episode and say hello in the live chat!

Iâm going to break the fourth wall here and speak directly to our dear listeners. When we started this podcast almost six years ago, I never imagined it would last this long or become such a fixture in the community. The goal was always to create a space aimed at enriching the listener's appreciation and understanding of lifting. I want to thank every single person who has tuned in, supported throughout the years and engaged with us in this journey. I feel very confident in the future direction of Iron Culture with the two Erics taking lead. We'll catch you in that next episode from now, until the end of time.
With heartfelt gratitude,
Omar

In this Iron Culture/Sports Nutrition Association/Sigma Nutrition Radio crossover episode, host Eric Helms is joined by co-host Danny Lennon and guest Alex Thomas. Alex is the president of the Sports Nutrition Association who started this association years ago when he was rudely awakened to the fact that he couldnât provide nutrition advice in his personal training clinic, despite having done so for years, having an RD on staff, and getting a degree in exercise science and nutrition. This prompted him to do a deep dive into scope of practice, insurance, legal requirements to provide nutrition coaching, and eventually to realise just how large of a gap there is in the nutrition coaching industry. Becoming aware of how common coach negligence leading to poorer consumer health is, spurred him to create the Sports Nutrition Association. Now SNA seeks to elevate the profession of nutrition coaching and protect the public. In this episode we navigate the confusing world of scope of practice, both legally and from a liability perspective, and why itâs not only an important box ticking exercise, but a fundamental part of serving your clients.

In this crossover episode of Iron Culture and MASS Office Hours, Dr. Trexler is joined by special guest Josh Pelland, a coach for Data Driven and a PhD candidate at Florida Atlantic University, to discuss Pelland's recent meta-analysis which investigates the effects of training volume and frequency on hypertrophy and strength outcomes. These data have created a lot of stir in the evidence based community as very high volumes seem to be associated with hypertrophy without a definitive plateau. But as you can expect, thereâs much more to the story. The analysis synthesizes data from numerous studies and quantifies dose-response relationships by which higher training volumes and/or frequencies may lead to greater strength and muscle gains in response to resistance training. In a thorough discussion of the paper, Pelland discusses nuances, such as the point of diminishing returns where further volume or frequency may yield less significant gains, and highlights how individual factors like training experience and muscle group-specific responses affect outcomes. Practical recommendations include tailoring volume to individual needs, utilizing periodization and volume cycling to maximize adaptations, and addressing common pitfalls such as overtraining. Further, in this live episode audience questions drive deeper exploration into the practical implications of the findings and strategies for optimizing training programs based on current evidence.

There is a great deal of fitness content about strategically modifying your diet or changing your physique. Many of these strategies may appear to be simple on paper, but they are inseparable from the complexity of human perception and emotion. Whether we like it or not, diet or physique manipulation inherently interact with concepts relating to oneâs confidence, body image, self-esteem, and relationship with food. Further, many fitness coaches and clients mistakenly believe that poor body image or self-esteem are improved by simply changing oneâs body. A growing area of interest in the fitness space aims to directly address and improve these outcomes by focusing on beliefs and behaviors in the absence of physique manipulation. In this crossover episode with Sigma Nutrition Radio and the Sports Nutrition Association, Eric Trexler and Danny Lennon are joined by Dr. Gabrielle Fundaro to take an evidence-based and practical look at the ways diet or physique modifications interact with confidence, body image, and self-worth.

Weightlifting came before powerlifting, but did you know weightlifting wasnât exactly the first barbell sport? Or rather, did you know that the first iteration of weightlifting was VERY different than what we see today in the Olympics? The history of weightlifting is fascinating, and in this episode of Iron Culture Drs Conor Heffernan and Cliff Harvey are back to share their experiences with, and the history of, All Around Lifting, the original barbell sport. With literally hundreds of potential lifts to compete in, All Around Lifters are barbell generalists rather than specialists, and both strong and versatile. Modern All Around meets are very similar to the original lifting competitions from the early 19th century before weightlifting centralised around the snatch, clean and jerk and clean and press (and eventually just the snatch and clean and jerk), and before modern strongman, powerlifting or CrossFit existed. While you may know Cliff Harvey as a nutrition researcher, he is also a former All Around world champion weightlifter and amateur historian. He shares his experience while Conor goes into the fascinating tale of how weightlifting began, and how modern All Around Lifting recaptures it.

How do we know what we know? And do we know what we think we know? If your answer is âI donât know,â 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 âevidence-basedâ world some people always claim to have things figured out entirely. In the case of hypertrophy, some people currently can explain with a âmodelâ 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, doesnât 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 âmodelâ really a model if nothing was actually modelled? Can it be valid if it is contradicted by dozens of controlled trials? Most importantly, will we ever be ok with feeling uncomfortable and embracing our ignorance in the search of knowledge? Or, are we doomed to repeat the mistake of prematurely clinging to intellectually satisfying, logical, complete, yet factually incorrect answers whenever there are gaps in our understanding that makes us uncomfortable?

Research moves slow, well, at least slower than we wish it did. But, that doesnât mean it doesnât 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.

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 âPanaâ 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 powerliftingâs 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.

The classic Iron Culture duo hosts this weekâs 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 âMuscle Confusion Principleâ to motor learning concepts like varied practice, thereâs 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 selection and variety for bodybuilding. So listen in on this episode as we talk through the history, science and culture of exercise variety for hypertrophy, as well as strength!

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 wonât 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 âneeds.â 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 Erics reconcile these complexities into a defensible mental model of how the needed training dose changes over time? Tune in to find out!

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.

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 youâll 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.

Walter Cariazo joins Omar and Eric Helms on Iron Culture to discuss his decade-long journey in powerlifting. Heâs 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 Omarâs YouTube channel) and photographer. The perennial lifelong lifter, Walter embodies the spirit of iron culture as a âblue-collar powerlifterâ who is optimizing his lifting pursuits within the constraints of life - approaching the pinnacle of the sport while doing so.

A long lifting career comes with plenty of ups and downs, so weâre accustomed to hearing stories about setbacks, comebacks, and perseverance from our favorite lifters. These setbacks can take many forms, but Jared Maynardâs 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 up for a remarkable recovery.
