I’ve written about BFR (“Blood Flow Restriction”) or “Occlusion” Training on and off since 2017. This modality of resistance training has been clinically proven as a way to effectively and safely “hypertrophy” muscle. So when I was recently visiting my AMAZING physical therapist Dr. Mark Bautista, I was surprised to see patients being treated with BFR cuffs. I asked Dr. Mark about it and I learned about the deluge of recent clinical studies that have broadened the usage of BFR to include injury-specific rehab/prehab, sports performance, endurance, strength as well as traditional hypertrophy.
