ABSTRACT:
The invention relates to the field of abdominal exercise with the operator using the sit-up or crunch movements. More particularly, an exercise apparatus that exercises the abdominal and back muscles with the lower torso of the operator supported by a moving seat while the upper torso of the operator is supported by a moving seatback. Continuous support of the lower back prevents back strain. The articulation of the seatback is coordinated with the movement of the seat. Adjustment is provided to adjust the rate of movement of the seat relative to the seatback. Handles are provided such that the arm muscles can assist the sit-up or crunch movements.
