A compact, easily storable abdominal exercise device is described that provides a sliding (to-and-fro) form of exercise for a seated user. In addition, the cushion may rotate so that it can also allow a swinging/twisting motion. Consequently, the sliding and/or the sliding+twisting modes of the exercise device allow a greater range of motions for exercising the muscles of the waist and help to stimulate firming and toning of the waist areas more effectively. |
