In this episode, Dr. Layne Norton interviews Professor Jeremy Loenneke — one of the world’s top researchers on blood flow restriction training. They break down how BFR actually works, why metabolite accumulation appears to be the primary driver of its muscle-building effects, practical self-application techniques, and whether expensive cuffs are even necessary.

Jeremy also shares his latest thinking on the hypertrophy vs. strength relationship, why muscle may be an underrated health marker (just like fat once was), his biggest concerns about the replication crisis in exercise science, and how he responds to critics who call BFR “gimmicky.”

Whether you’re an athlete chasing gains, a coach, or just training smarter, this is a must-listen deep dive into the science and real-world application of BFR.
