You can call it Blood Flow Restriction (BRF), occlusion, or Kaatsu, but the idea is all the same: Keep some extra blood in the muscles of your arm or leg and get a massive pump. But is this superior to working out the regular way? When should you use it, and does it have any effect on rehab/recovery? We ponder these questions and discus our own experience. Then, we bring in Layne Norton, someone with a long history of using this type of training, to help us understand what the actual benefits are. Layne holds a PhD in Nutritional Sciences from University of Illinois, and is an author, bodybuilding/figure/physique coach, and a professional powerlifter. Our ideas about the question start around 6:55. Layne runs down the facts starting at around 12:40. Huge thanks to Layne for being our expert. You can find him at BioLayne.com and on Instagram: @biolayne. Check out his new book, Fat Loss Forever, on his website. Hosted by Mike Farr (@silentmikke) and Jim McDonald (@thejimmcd).
