ABSTRACT:
An exercise apparatus includes a clamping means for fixing the apparatus to a vertical surface such as a door or a wall, an elastic resistance band and a resistance harness. In a preferred embodiment, the clamping means is a lag screw having a hook portion adjacent one end. On end of the resistance band is attached to the hook portion of the lag screw and the other end is attached to the resistance harness. In another preferred embodiment, the apparatus further includes an adjustment for adjusting the vertical location of the resistance harness relative to the clamping means, and the clamping means is a U-shaped bracket. The adjustment means includes a belt having one end attached to the U-shaped bracket, and the free end threaded first through an adjustment buckle and then through a hook attached to one end of the resistance band. The other end of the resistance band is attached to the resistance harness. In an alternative embodiment, the resistance harness includes a hinged resistance bar so that the apparatus is easy to use, transport and store. In a preferred method of using the exercise apparatus, a user extends the upper arms through an opening defined by the resistance harness and pulls the resistance harness using the abdominal muscles in the direction of the pelvis while bowing the lower back outwardly posterior tilt to extend the resistance band. Thus, the spine is elongated and all of the abdominal muscle groups are contracted without placing undue stress on the muscles in the lower back.
