I first started experimenting with Blood Flow Restriction (BFR) or “Occlusion” training back in 2017. At first I was skeptical of this gimmicky looking technique for “bio hacking” muscles to grow faster with less work. Frankly, I figured it was another unsafe or ineffective scam by the fitness industry trying to sell me something I don’t need. But, as a trainer, I try to have an open mind and test different lifting styles and products to gain firsthand experience to pass along to my clients. In the end I’ve found that with the right cuffs and under the right circumstances it can be a safe and helpful way to build muscle.
