Iron Culture Podcast
Hosted by Iron Culture
Two PhDs dissect the science, history, and philosophy of lifting, translating complex research into practical advice for serious lifters.
A graduate-level audio seminar on strength and physique sport, disguised as a podcast. Helms and Trexler, both active researchers, move beyond simple 'how-to' advice to dissect the nuances of scientific literature, debate the evolution of training concepts, and explore the historical context of lifting culture. It's a show about the 'why' behind the 'what,' treating lifting as a serious intellectual and practical pursuit.
“Unlike many fitness podcasts, Iron Culture is hosted by two PhDs who are actively publishing research and coaching high-level athletes. This allows them to blend rigorous scientific interpretation with practical, in-the-trenches experience, often discussing the limitations of research and the ethics of science communication itself.”
Who hosts this show
Iron Culture was founded by Eric Helms and Omar Isuf to explore physical culture beyond the gym floor. Now primarily hosted by Dr. Eric Helms and Dr. Eric Trexler, the podcast delves into the science, history, and philosophy that unites the diverse tribes of lifting. The hosts, both active researchers and coaches, engage in deep-dive conversations and Q&As, aiming to provide practical, evidence-based information on everything from programming and nutrition to the cultural issues facing the community.

What you'll be asked on this show

Episodes are typically structured around a central theme, such as a recent scientific debate, a specific training methodology, or a Q&A session answering listener-submitted questions. The dynamic is a peer-to-peer exchange of expert knowledge, not a host-guest interview.
