ABSTRACT:
Wrists and forearms exercise apparatus for use with a free weight, or weights, includes a cylindrical bar defining a central location with handles attached to opposed ends of the bar. First and second spaced-apart holes located equidistant from the central location extend completely through the bar immediately adjacent to the ends of the bar, and an open-topped channel is defined within the bar and extends between the holes. A flexible cable is positioned within the channel and normally extends downwardly through the holes. The free weight, or weights, are connected to lower looped ends of the cable so that the weight, or weights, are suspended and centered beneath the bar. Because the weight, or weights, are suspended beneath the bar from two locations equidistant from the central location of the bar, movement of the weight, or weights, from side-to-side is limited as the handles and the bar are rotated during use. This enables the user to exert equal torques and forces with both wrists and both forearms during exercise so that symmetrical muscle development is achieved.
