BFR Science


Shop PowerCuffs


Blood Flow Restriction (BFR) has existed for many decades but didn't catch on in America until about 2015. Doctors worldwide use BFR to enhance injury recovery and rehabilitation.

The same science is also highly effective during everyday workouts to strengthen muscles without the use of joint damaging, heavy weights.
