ABSTRACT:
The apparatus described herein includes a substantially rectangular and flat board having a longitudinal groove adapted to receive guide pins protruding from a disc-shaped weight resting on the upper surface of the board. The board is at an angle of about 30.degree. to 60.degree. with the floor or base on which the board is positioned. The raised end of the board is supported, preferably by an adjustable device, to provide the desired slant angle. Arms or straps are attached to the disc-shaped weight so that a person positioned at the raised end of the board can pull the weight upward along the surface of the board. The angle of the board allows a gravity force to be exerted on the weight, with the effect of gravity being increased by adjusting the slant of the board to a greater angle. Pulling the weight up the board and then releasing it gradually to allow its sliding back to a lower position and repeating the cycle, provides an effective exercising maneuver.
