Handmaster Plus strengthens the 18 hand muscles with one convenient continuous, easy-to-understand exercise. Therefore, no multiple hand exercises or grip-strengthening devices are required. Handmaster Plus combines 4 exercises up to 1. No wasted effort, no segmented routines, no confusion.
To maximize grip strength, the 9 muscles that ‘open’ the hand need to be strengthened and balanced with the 9 muscles that ‘close’ the hand. Modern studies on grip enhancers clearly illustrate that the ‘hand-opening muscles’ (grip stabilizers) ‘stabilize’ the ‘hand-closing muscles’ (grip action muscles) during all grip-related activities. This is new technology that only we have explored to this extent. If you train the hand-opening muscles (extensors and abductors) directly, you will limit strength, stability and performance in the fingers, thumb, hand, wrist, carpal tunnel, forearm and elbow.
