Ep 395: Science Communication Versus Commodification (ft. Dr. Nick Tiller)
Eric Helms hosts researcher and scientific skeptic Dr. Nick Tiller for a conversation on science communication versus "commodification" in health and fitness. After Tiller traces his path from UK sport science and work with GB Olympic athletes into scientific skepticism and writing, they cover what scientific skepticism actually is and its history (from Sagan, Randi, and the Bigfoot-and-UFOs era to today's focus on wellness misinformation), how people with little expertise came to dominate the health and wellness space, and the distinction between skepticism and cynicism. From there they get into research attempting to measure critical thinking and cynicism on validated scales, which claims people choose to scrutinize and the rise of AI-driven misinformation, the case for attacking claims rather than people, and why fitness and wellness have become so tied to politics and tribalism. The back half turns to Tiller's own late and reluctant embrace of social media as a tool, his book "The Health and Wellness Lie," and closing thoughts on the reality of monetizing science communication and his parting advice to make time each night to focus your attention — to read.

Ep 394 - Common Movement Questions
Iron Culture co-hosts Eric Trexler and Eric Helms answer four common questions about movement and lifting. Topics include anterior pelvic tilt, tibial torsion and asymmetry, butt wink, and Smith machine squats. They explain why recommendations depend on symptoms, experience, and goals, and why comfortable individual movement often matters more than enforcing "perfect" movement patterns.

Ep 393 - When Science Isn't Ready for "Prime Time"
Trexler and Helms step back from training specifics to talk about how science gets interpreted, communicated, and applied. Trexler opens with two anecdotes that exposed a blind spot in his own communication — a one-minute clip of a talk on the Minnesota starvation experiment that drew online backlash, and a classroom tangent on macaque calorie-restriction research that a colleague worried could nudge students toward disordered eating — both cases where true, interesting science left too much room for misapplied conclusions. That leads into the academic-versus-applied distinction (when an idea is "ready for showtime"), what Trexler has absorbed from science communicators and evolutionary-biology seminars outside fitness, the case for structuring science as story, leading with a question rather than an attack on social media, and modeling intellectual humility. The back half covers how to tell when information isn't "ready for prime time," a worked example from a Mass article on weight-variability research, and the shared pull — across researchers, communicators, and audiences alike — to carry findings past what the evidence supports.

Ep 392 - Training Frequency for Hypertrophy
Trexler and Helms dig into training frequency and hypertrophy, prompted by a wave of recent discussion and two new papers: a new original study comparing three weekly sessions of three sets against one session of nine, and a new preprint from an independent research team utilizing the openly available data from Pelland's previously published meta-regression. They trace the long history of the frequency debate (including Helms's own shifting position), review where the science had settled, and put the current online discourse and the reanalysis under the microscope. The back half turns practical: a state-of-the-science recap, higher frequency as a tool for distributing volume and managing fatigue, and "zigging where the data zags," with a personal example of practical application.

Ep 391 - What Can You REALLY Learn From Pre-Steroid Era Bodybuilders? (with Dr. Conor Heffernan)
This episode looks at bodybuilding before steroids became widespread, arguing that the era is far more useful (and more complicated) than the usual "pure, simple, natty golden age" story. Drs Eric Helms and Conor Heffernan break down how strength sport, judging standards, gym access, and culture shaped physiques from the 1940s through the 1950s. The big takeaway is that early bodybuilding was not a direct comparison to modern natural bodybuilding. The sport was tied to Olympic weightlifting, evaluated with very different criteria, and influenced by training tools and social norms that changed the entire game.

Ep 390 - Is Muscle Loss Really a Big Deal?
Bodybuilders are laser-focused on retaining as much muscle as possible while dieting, and for very good reason. In that context, the smallest details matter. But what about everybody else? This episode explores a hot take on weight loss, lean mass loss, and why the usual fear of losing muscle may be overstated in the context of successful long-term weight loss. Drs Eric Helms and Eric Trexler break down what lean mass loss actually represents, how body composition changes in obesity differ from bodybuilding or weight cycling, and why the health benefits of sustained fat loss substantially outweigh moderate losses in fat-free mass.
