Ep 310 - Are People Getting "Metabolic Stress" Wrong?

In today's episode, Drs Trexler and Helms discuss a wide range of fitness topics including metabolic stress, "the pump," targeting the different heads of the biceps, individualising diets and supplement protocols, maximal rates of fat loss, blood flow restricted training, the philosophy of science, and much more! We had some technical issues while recording this episode live, but it's all fixed now with the wonders of editing. If you don't understand a couple of the jokes, they're referring to chaos that has been deleted.

Om Podcasten

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.
