Blood Flow Restriction (BFR) training has gained recent popularity in the rehabilitation, fitness, and performance industries over the past decade. Its origins date back to the 1960s, when scientists first noticed improved walking tolerance in people with intermittent claudication after a physical training program. This discovery sparked a wave of research into the mechanism and clinical use of BFR, some of it useful and some of it haphazardly dangerous.
However, skepticism is warranted whenever an intervention promises that low-intensity exercise with a blood pressure cuff can improve strength, performance, recovery, and even reduce pain. That said, we still need to weigh the breadth and quality of the research before drawing conclusions about its real-world application and benefit.

Key Points
- Specifically, for patients who can’t tolerate high loads, low-load BFR training (15-30% 1-RM) can produce hypertrophy gains similar to conventional high-load training.
- Overall, training pressures should fall between 40-80% LOP for the LE and 30-60% LOP for the UE. Because wider cuffs need lower pressures, they also tend to be more comfortable for patients.
- Before applying BFR, screen every patient for vascular compromise, clotting disorders, embolism risk, renal compromise, and hypertension. Then, tailor the pressure to the individual patient, the exercise, and the position they’ll use.
