Pagina seriei•Feed

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.

In tonight’s episode of Iron Culture, Eric Trexler and Eric Helms discuss various topics related to fitness, training, and research. They share personal updates, including the toll that Helms' intense training regimen is taking on his face. The discussion then shifts to the upcoming NFL combine, highlighting the impressive athletic feats expected from past combine participants. In the main segment of the show, Trexler and Helms discuss the nuances of lengthened-biased training research – more specifically, why we shouldn’t give up on the strategy just because a few studies reporting non-significant results have come along. In this conversation, Trexler and Helms explore the concept of sampling error in research, emphasizing the importance of understanding some foundational statistical concepts and the need for several studies to draw reliable conclusions. They explore the challenges of uncertainty in evidence-based practice, the balance to strike between mechanistic and empirical approaches to understanding exercise and nutrition, and the resistance to change in learning. Finally, they engage in a rapid-fire Q&A session addressing a handful of fitness-related questions. The MASS crew records Iron Culture LIVE on YouTube, Monday nights at 7pm eastern time.

In this episode of Iron Culture, hosts Dr. Eric Helms and Dr. Eric Trexler are joined by Dr. Martin Refalo to discuss their recent meta-regression study on protein intake and its effects on muscle hypertrophy. They cover Martin's background, the initiation of the project, the methods used, and key findings, followed by a discussion of some critiques that have been generating discussion on social media platforms. The conversation emphasizes the importance of understanding statistical approaches in research and the implications of their findings for the fitness community. In this conversation, the Erics and Martin discuss the complexities of statistical modeling in nutrition research, the importance of parsimony, the risks of overfitting, and the challenges of controlling for covariates. The conversation also touches on the debate surrounding scaling protein recommendations by fat-free mass versus total mass, critiques of previous research on protein requirements for hypertrophy, and the ways in which these new findings support (and contradict) the authors’ previously held biases. Throughout the episode, they reflect on the evolution of research in the fitness industry and the importance of engaging with critiques and feedback. Ultimately, they emphasize the need for thoughtful, contextualized, individualized application of their findings while acknowledging key limitations of their work.

In this episode of Iron Culture, Eric Helms and Trex discuss a variety of evidence-based fitness topics. In this conversation, Dr. Trexler and Dr. Helms delve into the complexities of muscle gain, recovery, and the role of nutrition in performance. They discuss the nuances of identifying plateaus in training, the impact of training volume, the importance of food quality, and how psychological factors can influence recovery and performance. The dialogue emphasizes the need for a balanced approach to training volume and exercise selection, as well as the impact of nutrition on overall health and performance in bodybuilding. They also discuss modern theories and practical applications surrounding body weight regulation and the neurophysiological factors influencing obesity. They explore the gravitosat theory, discuss the implications of muscle gain on body weight regulation, and examine the concept of upper and lower intervention points. Additionally, they touch on powerlifting training strategies and the significance of volume in strength training.

Ep 308 - The Future of Natural Bodybuilding (w/ WNBF Pros Alberto Nuñez and Steff Noble) 1:34:03

In this episode, Eric Helms is joined by returning guest, his fellow 3DMJ coach and WNBF Pro bodybuilder, Alberto Nuñez, who is also the male WNBF athlete rep. In addition, they are joined by first time guest Steff Noble, a WNBF Figure pro, experienced coach, and president of WNBF UK. The trio first reflects on what was arguably the most competitive natural bodybuilding season to date, and the overall state of drug free bodybuilding, which in many ways is flourishing. There is more interest, higher competitive levels, higher productive quality in some regions, and in some countries natural bodybuilding is growing faster than enhanced bodybuilding. In North America, while some federations are doing better than others, the market demand for natural bodybuilding is obvious, as the NPC has made a concerted push to enter the natural bodybuilding scene, promoting drug tested shows in the US and Canada (as well as overseas), and even offering the chance to turn pro at the biggest natural events, with promises of drug tested pro shows on the horizon. What does this mean for natural bodybuilding? Is this a good thing, a threat, the beginning of a new era, or the beginning of the end? Further, what does the natural bodybuilding community need to do collectively to secure its future? Join us in this episode as we review not only the 2024 natural bodybuilding season, but discuss the future of the sport.

Ep 307 - Are Lengthened Partials Overrated? 1:37:03

In this episode of Iron Culture presented by MASS, Dr. Eric Trexler and Dr. Eric Helms explore the science and debate surrounding lengthened partials, a training technique often celebrated for its hypertrophy and strength benefits. Drawing on recent studies, they discuss how emerging evidence challenges some hyperbolic claims of lengthened partials as a superior training method, suggesting instead that their effectiveness is highly context-dependent. The hosts advocate for viewing lengthened partials as a complementary, rather than revolutionary, tool in exercise programming. After the main discussion, the episode transitions into a series of listener questions, with Dr. Trexler sharing his renewed enthusiasm for training (and his current approach to training) as he recovers from surgery. The hosts also address topics like the importance of omega-3 intake during low-fat diets, the diminishing returns of high training volumes, practical applications of two-a-day training splits, and the impact of high-protein diets on digestive health, emphasizing fiber and dietary diversity. They also discuss caffeine’s role in sleep disruption, underlining caffeine timing as an easy way to improve sleep quality, among many other topics.

In this crossover episode of Iron Culture, co-hosts Danny Lennon and Eric Trexler are joined by fitness professional and fellow Sports Nutrition Association (SNA) advisory board member Laurin Conlin. Together, they dive into the complex relationship between mental health, physique sports, and fitness coaching. Laurin shares her personal experiences and insights on how disordered eating and body image issues often arise in competitive physique sports, and how these behaviors can permeate into the broader fitness space. The conversation highlights strategies for recognizing and reducing harmful behaviors, the importance of revisiting problematic terminology in the industry, and the value of maintaining a holistic perspective in coaching. Practical advice for fitness practitioners is grounded in evidence-based approaches like motivational interviewing, helping coaches better support clients navigating these challenges. The episode concludes with resources for learning more about the SNA and its initiatives in advancing sports nutrition practice.
