Bundle of 4: This set includes 2 leg bands measuring 2" W x 40" L and 2 arm bands measuring 2" W x 26" L, along with a carrying bag for convenient storage and transport. Designed for resistance training, these bands help apply consistent pressure to the working limbs during exercise. The applied pressure may assist in limiting blood flow to targeted muscles, which can support muscle activation during workouts. Supports Muscle Development: Research indicates that exercise combined with external resistance can stimulate muscle protein synthesis and activate key physiological pathways involved in muscle growth. Some studies suggest that controlled occlusion during training may enhance muscle adaptation and support hypertrophy when used with low to moderate resistance. Build Lean Muscle with Light Resistance: When used properly, occlusion-style training with these bands may promote muscle development using lighter loads (typically 10-30% of 1RM). When combined with high repetitions and short rest periods, this method may produce results similar to those achieved with heavier loads, making it a practical option for individuals seeking muscle tone and endurance without heavy weightlifting. Durable and Comfortable Design: Featuring a strong elastic strap, each band includes a quick-release buckle and elastic loop for secure fit and easy adjustment. The design allows for a snug, comfortable fit during use and can be quickly fastened or removed. The bands maintain their shape and elasticity after repeated use. This package includes 4 bands for use in occlusion training, ideal for both upper and lower body workouts. Designed for performance and convenience, these bands are a practical addition to a regular fitness routine.
