ABSTRACT:
The present invention concerns that of a new and improved apparatus for exercising, conditioning, and strengthening various hand, wrist, and forearm muscles. The apparatus comprises a central coil that has two attached handles. By squeezing the handles, an individual can strengthen various hand, wrist, and forearm muscles. An adjustment mechanism is enclosed which will allow an individual to change the tensile strength within the central coil, requiring a greater amount of power to move the handles together the same distance, thereby enabling the apparatus to exercise the short-twitch muscles (strength muscles) rather than the long-twitch (endurance) muscles.
