Blood Flow Restriction Q&A with Jim Stray-Gundersen

Oct. 1, 2021

Jim Stray-Gundersen, MD is a world-renowned expert in Sports Medicine, Exercise Physiology and Training for Sport Performance. Drawing from his lifetime of experience with elite level athletes and clinical populations, Jim developed and co-founded the B Strong Training System using Blood Flow Restriction (BFR). The system works by applying cuffs to the arms and legs to temporarily restrict venous return without occluding arterial inflow. Put simply, blood flow restriction prompts an outsize response from the brain to speed up the normal process of repairing and rebuilding damaged tissue with lighter weight and a reduced risk of injury compared to traditional weight lifting. Jim predicts the B Strong Training System will change how the world gains the benefits of exercise, improving longevity and quality of life.

On this podcast, Jim discusses the important difference between the B Strong system and other BFR devices on the market, and answers questions about application and safety when training with blood flow restriction. He talks about how athletes and like-minded people are using BFR and shares some common user errors and ways to avoid them. Jim also describes his new professional training course available to anyone interested in learning more about the theory and application of BFR. Or - even better - for the next 14 days you can get the B Strong BFR Training System for 20% off using the code Kelly20.
