TheraBand™ Soft Weights are hand-held, ball-shaped weights that provide an excellent way for unique learners to add weight to activities that cross the midline. Using these weights can build hand and wrist strength as well as improve the proprioceptive system overall. They are unique because the size of the ball, with a diameter of 4.5″ (11.4cm) does not increase as weight increases, allowing for a consistent and functional grip. Available in a variety of weights starting at just 1.1 pounds for smaller children and beginners. Sold individually.
