Extra Wide Bands: These Occlusion Bands are extra thick and 2 inches wide to help you reach optimal occlusion during your occlusion training workouts.Increased Factors For Muscle Growth: Studies show that practical blood flow restriction training can increase muscle protein synthesis, NOS-1 expression and mTOR signaling, resulting in increased muscle growth.Quicker Lean Muscles And Superb Tone Without Lifting Heavy Weights: The occlusion straps induce hypertrophy at very low loads (usually 10-30% of a 1RM). When performed correctly, the results achieved are typically similar to those achieved with 80% 1RMs. Extra-Strong And Super-Comfortable: Our bands are easy to strap up, effortless to release in between sets or exercises, and exceptionally comfortable. Each order comes with 2 bands to allow you to exercise both legs or both arms at the same time.Material: Natural latex ribbon elastic band Size: length 25in(60cm), width 2in(5cm)
