BUNDLE PACK OF 4: Our new PRO Bands come in a set of 4, including 2 leg bands measuring 2" W x 40" L and 2 arm bands measuring 2" W x 26" L, plus a carry bag for convenient storage. Designed for occlusion training, these bands provide controlled restriction to help target working muscles. The bands are engineered to support muscle engagement during exercise by managing blood flow to the limbs. INCREASED MUSCLE GROWTH SUPPORT: Research indicates that certain training methods can support muscle protein synthesis and activate key physiological pathways associated with muscle development. When used properly, tourniquet-style bands during exercise may contribute to enhanced muscle adaptation. BUILD LEAN MUSCLE AND IMPROVE TONE WITH LOW-INTENSITY TRAINING: These occlusion bands are designed to be used with light resistance (typically 10-30% of 1RM). When combined with high-repetition, low-rest routines, they may help achieve results similar to those from high-load training. The bands offer a method to support muscle endurance and tone without heavy weights. DURABLE AND COMFORTABLE DESIGN: Featuring a strong elastic construction, quick-release buckle, and an elastic loop to manage excess length, these PRO bands are easy to apply and remove. They are designed for comfort during use and maintain their shape and elasticity over time. Each package includes 4 bands ideal for limb training applications.
