ABSTRACT:
The upper body exerciser assists the user in the performance of sit-up exercises. An inclining and reclining backrest is pivotally attached to a frame. An independent backrest support is pivotally attached to the frame behind the backrest. A pair of handles are operatively connected to the backrest support by a cable and pulley system. A pair of torsion springs are connected to the backrest support so as to operatively engage the backrest. The user pulls down on the handles to move the backrest support to lift the backrest through a first portion of a sit-up exercise. The torsion springs then propel the backrest forward to assist the user in completing the exercise.
