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.
