Occlusion Training Bands, Bicep Muscle Training Straps (5 pieces/pack of 5 different colors). These resistance bands are designed for muscle training and fitness exercises. INCREASED MUSCLE GROWTH: Research indicates that exercise can support muscle protein synthesis and activate key signaling pathways related to muscle development. Some studies suggest that controlled resistance during exercise may contribute to enhanced muscle growth potential. BUILD STRENGTH AND TONE WITH LIGHT RESISTANCE: These training bands allow for low-load muscle engagement, typically using 10-30 percent of maximum effort. When used with moderate repetition and short rest periods, they can help achieve muscle endurance and toning results. The design supports effective workouts without the need for heavy weights, promoting lean muscle development. DURABLE AND COMFORTABLE DESIGN: The straps are easy to secure and remove, providing a comfortable fit during use.
