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.

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.

Who is the strongest? Is it the person with the biggest Powerlifting total? Weightlifting total? The current Worlds Strongest Man/Woman Champion? Or, perhaps, the current Arnold Strongman Classic Champion? It’s an oft-debated question, typically occurring around the proverbial fitness water cooler. However, recently Dr. Kind, Dr. Veit, Dr. Heffernan, and our very own Dr. Helms made this debate into a multidisciplinary academic paper. Specifically, they asked the question through the lens of history, what has strength meant in society since the dawn of physical culture, what is strength philosophically, and finally, what is strength objectively, as measured in sport and exercise science? Join us as we discuss why asking this question is important, and how these very different disciplines turned out to be quite complementary in providing an answer.

This week we’ve got a MONSTER episode in the form of a live Q&A episode with Dr. Helms and Dr. Trexler. The Good Doctors begin with a recap of the recent WNBF World Championships, followed by an insightful discussion about whether or not humans have a “factory error” in our design that promotes obesity. This is followed by a number of listeners’ questions about functional anatomy, exercise selection, the importance of the eccentric phase of a lift, factors impacting reps in reserve (RIR) accuracy, biceps contributions to back exercises, hypertrophy considerations for the deadlift exercise, mini-cuts, set-to-set fatigue, energy expenditure limits, “delayed” hypertrophy, how to tell if you’re a creatine nonresponder, and velocity-based training.
