Abstract
An exercise apparatus having a support frame, an exercise resistance device such as a weight stack, and a linkage such as a cable and pulley linkage extending from the weight stack to various exercise stations, has a lever arm pivotally mounted on the frame for rotation about a first horizontal pivot axis into any one of a plurality of selected orientations relative to the frame, and a locking device for locking the lever arm in the desired orientation. A cable linked to the exercise resistance extends around a first pulley attached to the arm for rotation about a second horizontal axis spaced forwardly from the first and a second pulley at the end of the arm on the lever arm and has a connector at its free end for connecting the cable to a selected exercise device or to a tie-off point. Adjusting the orientation of the lever arm raises and lowers the point of connection to the exercise resistance or tie-off, and allows adjustment for different types of exercises.
