The Complete Hand Strengthener

Finger extensor muscles, located generally on the back of the hand, wrist & elbow, contract aggressively to support any hand or grip strength action. Every time the hand grips, the finger extensor muscles are activated as much as the finger flexors. BOTH muscle groups must be strong, healthy & balanced through proper hand exercise. Because little attention has historically been placed on this stabilizing role, imbalance, performance limitation and injury have been rampant in sports, music and ergonomics. Extensor muscles have been dangerously omitted – an error that costs industry billions of dollars per year and could easily be solved through proper hand exercise training.

Traditional hand exercise applications originally included a ‘rice box’ application, whereby the patient immersed his or her hand in the rice and opened and closed it naturally against the resistance of the rice. Limitations to the exercise (and inconvenience) rendered it nearly extinct as a hand exercise. Handmaster Plus is the vital and convenient evolvement of the basic rice box idea of natural resistance.

The result is maximum strength, balance & circulation from the tips of the fingers to the elbow. The result is the #1 rated complete hand exerciser on the market today.
