Abstract

Abstract An exercise device comprising a shoulder harness which is connected through a line extending over a pulley to individual handle members. The pulley is secured to a fixed support and the person using the device is positioned on the floor near and facing the support. The exercise device is used to assist in the performance of sit-ups from a variety of initial positions. As force is applied through the handles to move them away from the pulley, this force is transmitted through the connecting line to the shoulder harness to urge it toward the pulley.
