Dr Jim Stray-Gundersen MD is Board Certified in General Surgery and a world-renowned expert in sports medicine, exercise physiology and training for sports performance. He has worked for 35+ years with Olympic and professional athletes, including the US, Norwegian, German, and Canadian national teams, as well as with NASA, Special Forces, and all levels of the US Military. Jim currently serves as the sports science advisor for the US Ski and Snowboard Association (USSA) and is the founder of the SG Performance Medicine Center in Park City, Utah.

On this podcast, Dr Stray-Gundersen defines the mechanisms and application of Blood Flow Restriction (BFR) training and its effect on overall health, performance, power, and strength. He explains how BFR can deliver muscle gains identical to traditional strength training but with less weight, reduced risk of injury and faster recovery, making it a viable training option for people of all ages and fitness levels. He discusses the safety of BFR and the potential of this technique to revolutionise training and rehabilitation, particularly at this time when many of us no longer have access to a gym.
