Iron Culture

Eric Helms & Eric Trexler
Iron Culture

Iron Culture was started by Eric Helms and Omar Isuf, now currently hosted by Eric Helms and Eric Trexler with Omar as a returning guest, as a means of exploring the world of physical culture and attempting to distill a unified philosophy of lifting and to help listeners find greater meaning from the iron. The lifting community has become fractured over the last ~70 years and this Podcast will attempt to explore the fundamental threads that unite these different tribes. The Podcast focuses on dispensing practical, useful information to the listener, bouncing from history, to philosophy, to contemporary lifting culture issues, to science. This can range from teaching the audience about lifting, programming, nutrition, supplements/PEDs and the history of lifting culture. The format includes casual conversations between the two hosts on a variety of topics, discussions with a panel of experts and interviews with authoritative figures in the lifting community.

    Ep 297 - Is More Volume Always Better? (feat Josh Pelland PhD(c))

    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, there’s 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.

    An Evidence-Based Look at Body Image and Self-Worth

    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 one’s 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 one’s 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. 00:00 Welcome to another crossover episode (passively) dominated by Iron Culture 02:09 Defining body image and self-esteem 07:49 Relationship with food and weight stigma 21:22 Are your behaviours and beliefs really sustainable? 32:13 Different approaches to safe weight modification 39:19 Screening for risk factors and contraindications 47:20 Scope of practice and individuals who fall into the gaps 53:20 Interventions and approaches for improving body image  58:28 Closing out with some links Sports Nutrition Association https://sportsnutritionassociation.com/ Sigma Nutrition https://sigmanutrition.com/

    All Around Lifting: The First Form of Competitive Lifting (with Drs. Conor Heffernan & Cliff Harvey)

    Weightlifting came before powerlifting, but did you know weightlifting wasn’t 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. 00:00 Omar? And All Around lifting? 02:10 Welcoming back Drs. Conor Heffernan and Cliff Harvey and where everything lifting started 07:01 The format and how to prepare for All Around Lifting 15:11 The attraction of All Around Lifting 24:40 A deep dive into the history of All Around  38:49 Specialisation vs generalisation and accessibility of All Around 55:05 ‘Evidence-based’ training and individualisation  1:05:28 Cliff’s experience competing 1:15:10 Reframing your perspective and goals as you progress and age 1:20:35 Where to learn more about (and participate in) All Around Lifting and closing out https://www.iawa.uk/ https://www.usawa.com/ https://www.youtube.com/@USAWAVideos https://www.youtube.com/user/dinnie40

    What Causes Hypertrophy?

    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 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? 00:00 Do you know what you know? 04:56 Fitness content creators and models of hypertrophy Refalo 2023 Influence of Resistance Training Proximity-to-Failure on Skeletal Muscle Hypertrophy: A Systematic Review with Meta-analysis https://pubmed.ncbi.nlm.nih.gov/36334240/  Robinson 2024 Exploring the Dose-Response Relationship Between Estimated Resistance Training Proximity to Failure, Strength Gain, and Muscle Hypertrophy: A Series of Meta-Regressions  https://pubmed.ncbi.nlm.nih.gov/38970765/ 17:15 Studies in sport science without black and white results/answers and mathematical models 27:55 (Dis)confirming models and considering scientific evidence The Evidence is Lacking for “Effective Reps” by Greg Nuckols https://www.strongerbyscience.com/effective-reps/ Grgic 2018 Effect of Resistance Training Frequency on Gains in Muscular Strength: A Systematic Review and Meta-Analysis https://pubmed.ncbi.nlm.nih.gov/29470825/ 43:01 Engaging in dialogue regarding these models 48:24 Closing out this overdelivering 50 minute episode

    Cutting Edge Research on Volume, Protein & Cardio

    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.
