The interosseous muscles are the cornerstone of hand function, they provide the foundation for all hand movements. They are located between the metacarpals and consist of palmar and dorsal muscles that are responsible for finger adduction and abduction.

The power grip is a grip formed with the fingers and thumbs act against the palm to transmit force against an object. Of all the ways we grasp and squeeze objects the power grip is our strongest. Often when holding there may be tugging, twisting, pulling, yanking as we try to accomplish control. As the hand squeezes there also must be abduction and adduction of the fingers to assure the fingers do not separate and diminish power.

Finger Ab and Adduction

When training the hands include abduction and adduction of the fingers, this will dramatically increase hand strength and the control of objects. Fill your grip cart with training tools that Get each digit Strong.
