ABSTRACT:
A curved plate is attached to the back of a couch together with a pair of inverted U-shaped bars projecting forwardly over a front surface of an upright cushion of the couch. A tension cord is attached at a bottom end to a tension clamp under the couch and at a top end to a bracket mounted to the curved plate. A push rod turns the tension clamp to remove tension on the tension cord and allow either shortening or lengthening of the tension cord. A body harness is attached via a retractable elastic cord to a ring on each of inverted U-shaped bars. An exerciser bends forward to move the elastic cords and cause resistance against abdominal and associated mid-section muscles.
