Throughout the years, we hear about the latest innovations in fitness that claim to change the way we’re going to workout forever. Although most of these trends don’t really catch on, there is always one that manages to break through and get identified as a game changer. Well, the buzz right now is about “blood flow restriction training.” It is one of the newest training tools to hit both the rehab and sports performance worlds and it’s also being recognized as a potent tool for all of us aging baby boomers. There’s a lot of research that supports it, which is why Blood Flow Restriction or BFR is becoming more popular with athletes, physical therapists, trainers, and even celebrities like Mark Wahlberg.    While the idea has been around for decades, it’s only now that we’re seeing it becoming more mainstream...and largely because of our next guest, Dr. Jim Stray-Gundersen. Jim runs the SG Performance Medicine Center. He is also the chief medical officer of B STRONG, a Utah based company he co-founded in an effort to make blood flow restriction training safe, effective, and affordable for the general public.  For more from Kathy, visit www.kathysmith.com/podcast.
