Literally, time to strap in for this one folks! Blood Flow Restriction training: hypertrophy training with light weights made as just effective as heavier weights by putting a wrap or cuff around an arm or leg! It sounds like a gimmick, but there are actually two decades of published research looking into this intervention. We're joined by returning guest and physical therapist Dr. Nick Licameli and Dr. Nick Rolnick, a first-timer Iron Culture guest who has not only published peer-reviewed articles on BFR for bodybuilding but also uses it extensively in his practice as a physical therapist. Not only do we learn about BFR in this episode, and its implications for mechanisms of hypertrophy among other things, but it serves as a foil to better understand gimmicks vs the real deal in fitness.
