The Handmaster Plus is used to strengthen and balance the muscles of the finger, thumb, hand, wrist, forearm and elbow for both enhanced sports performance as well as prevent repetitive stress injuries. The Handmaster Plus strengthens both the front (flexors) of the hand when squeezing the ball and the back (extensors) when opening the hand. This hand exerciser uniquely works through a full, natural, three-dimensional range of motion. The reciprocal muscle exercise strengthens, conditions and balances the tissue of the hand, wrist, fingers and forearm.
