Occlusion bands, also known as blood flow restriction (BFR) training, can work on many body parts, including the upper body, lower body, and even the chest and glutes. Our 2-inch wide bands for glutes & arms are designed for superb restriction of blood flow through the working limb to the targeted muscles during workouts. Each set contains two 2"W x 40"L occlusion training straps. Our patented blood flow restriction training bands for arms and legs induce hypertrophy at very low loads. When performed correctly, results are typically similar to those achieved with 80% 1RMs. Studies show that practical blood flow restriction training increases muscle protein synthesis, NOS-1 expression & mTOR signaling. BFR Bands help increase muscular size at low training volumes and intensities.
