Blood Flow Restriction (BFR) 

"Personalized Blood Flow Restriction (PBFR) is the application of a specialized tourniquet system to a proximal arm or leg inflated to a personalized and specific pressure to reduce blood flow to an exercising extremity. The application is brief and intermittent, typically about 6 minutes per exercise. A session can last up to 30 minutes based on the specific exercise protocols. Under normal circumstances, to increase strength and hypertrophy a person would need to lift a significant amount of weight. With PBFR, you can create significant strength and hypertrophy gains with loads as low as 1-10 lbs.

 Aside from increases in performance in the general population, post-surgical knee and shoulder patients will find the greatest benefits from PBFR."
