Buckle Strap: Reach your fitness goals, with no sweat (well, some sweat). Easy to strap on and effortless to release, the buckle on our occlusion bands is perfect for one-handed operation. Symmetry Training: Our PRO X BFR bands for women and men include a pressure-tracking system to make sure you're giving equal training to both arms. Muscle Growth: Our blood restriction workout bands induce hypertrophy at very low loads (10-30% of a 1RM) and can increase muscle protein synthesis, resulting in increased muscle growth. Lean & Tone: Designed to offer the most targeted blood flow restriction for maximum muscle gain, our PRO X occlusion training bands reduce oxygen supply to the muscles to slow twitch muscle fibers and diminish their response to workout loads for faster muscle gain. Extra Comfortable: Don't get pinched by low-quality blood flow restriction training bands. These BFR bands for men and women make sure you stay at peak comfort while achieving your peak pump.
