Soft Weights allow users to increase weight in resistive training and rehabilitation programs without changing grip or technique which is fundamental to the principles of progressive exercise. Pliable PVC shells filled with steel and polypropylene pellets provide six levels of progressive weight training minimize risk of injury damage if dropped. Support broad range of one or two-handed strengthening plyometric balance mobilization activities; promote functional grip strength development. Standard 4.5 diameter; Thera-Band color coding simplifies recognition integration into programs.
