Handmaster Plus strengthens the 18 hand muscles using one convenient continuous, easy-to-understand exercise. Therefore, there is no need for multiple hand exercises or grip strengthening devices. Handmaster Plus combines 4 exercises into 1. Thus, no wasted effort, no segmented routines, no confusion.
To maximize grip strength, the 9 muscles that ‘open’ the hand must be strengthened and balanced with the 9 muscles that ‘close’ the hand.
