This is the exercise apparatus that strengthens your wrists and forearms as additional training for racquet and ball sports. Unlike free weights that can be awkward and unwieldy for wrist and forearm conditioning, the cushioned exerciser secures your forearm while you grasp the foam-padded handle that can be adjusted to your hand size. A cable and spring mechanism provides resistance as you curl your wrist; three levels of resistance offer a more vigorous workout. You can also reverse your grip to perform wrist extensions. 13 1/2" L x 6 1/2" H x 6" D. (1 1/4 lbs.)
