Strengthen your wrists and prevent stiffness in an easy and low-risk way!
The LED Wrist Trainer Ball is the easiest way to loosen up stiff wrists and add strength to those joints no matter where you are. Simply crank up the flywheel with the attached string, hold the ball facing downwards, and rotate your wrist gently to keep the wheel rotating. This continuous action of twisting and rotating your wrist, in turn, helps build strength, flexibility, and endurance.
