Iron Culture presented by MASS

In this episode, Eric Helms and Steve Hall explore the nuances of nutrient timing, carbohydrate intake, training frequency, and the importance of individual responses in bodybuilding. They emphasize practical strategies backed by science and share insights on optimizing performance and recovery.

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.

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.

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.   Join us for new episodes of Iron Culture on Tuesdays at 5:30 pm eastern time!

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.
