International ClassA63B 021/00AbstractThe application discloses a handle for an exercise machine having a force resistor such as the cable type wherein a weight stack supplies resistance to movement of the handle along a path through an interconnecting cable system. The handle includes a grip supported on an elongate arm. A base includes structure for connecting the handle to the force resistor. A ball joint connects the arm to the base to enable simultaneous rotation of the arm about its length axis and pivotal movement of the arm in an orbital fashion relative to the base to provide an expanded range of positions of the user's hand during opposed movement of the handle along the path.Other References
