Blood Flow Restriction (BFR) training is a technique that involves the application of a specialized cuff to partially restrict venous blood flow out of the working muscle while maintaining arterial inflow. This creates a controlled, low-oxygen (hypoxic) environment within the muscle, enhancing the physiological response to low-load exercise.

By simulating the effects of high-intensity strength training, BFR allows individuals to build strength, promote muscle growth, and stimulate key hormonal responses—using as little as 20–30% of their one-rep max. It’s particularly valuable for those recovering from injury, surgery, or pain, where traditional heavy lifting may not be appropriate, offering a safe and efficient path to regaining strength and function.
