TheraBand Soft Weights are hand-held, ball-shaped isotonic weights that provide a soft alternative to traditional isotonic dumbbells. These weights offer more versatility for strength training and rehabilitation exercises. The unique design ensures that the size of the ball, with a diameter of 4.5 inches, does not increase as the weight increases, allowing for a consistent and functional grip. This feature allows for either unilateral or bilateral exercise progressions, either independently or with a partner.
