Feature:1. IMPROVE POWER AND HYPERTROPHY WITH OCCLUSION TRAINING Using BFR 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, which means more results with less effort.2. INCREASED FACTORS FOR MUSCLE GROWTH Additionally, resistance training with BFR training bands and low relative loads also displays greater post-exercise muscle protein synthesis, higher growth hormone elevations, and more robust molecular signalling responses than comparable conventional resistance training with matched loads.3. WE HAVE THE PERFECT BFR TRAINING BANDS FOR YOU We offer 2 different kinds of Occlusion Bands to achieve perfect blood flow restriction to your muscles for maximum growth. Short: Perfect for Arms, Long: Perfect for Legs.4. HIGH QUALITY Our BFR bands use a natural latex ribbon elastic band allowing you to stretch the band to the desired level of tension controlling the amount of occlusion. The simple but strong locking mechanism secures your occlusion and makes sure it doesn't pop loose mid-set.5. PACKAGE & SERVICE Package List 4 pack bands (2 Bicep Bands,2 Leg Bands) .
