Abstract: An abdominal exercise device includes a support frame defining a first axis and a second axis generally perpendicular to the first axis. A seat assembly associated with the support frame includes a seat which pivots about the first axis and is laterally and arcuately slidable about the second axis. The exercise device includes a footrest and a bar that attaches the footrest to the seat assembly such that the bar and the footrest pivot with the seat about the first axis.

Abstract: An exercise apparatus that will exercise at least five groups of muscles is disclosed. The exercise apparatus exercises the abdominal muscles, the serratus muscles, the intercostals muscles and the leg muscles. The apparatus uses a seated position for the person exercising and the exerciser is seated on a swing. When the exerciser contracts his or her abdominal muscles while lifting the legs, the swing rotates such that the exerciser's feet rotate upward. When the exerciser releases tension on the abdominal muscles, the apparatus goes back to its original position. When the exerciser bends forward, the above four groups of muscles are exercised.
