Abstract: Apparatus for aiding a person during a physical exercise. Two relatively flat guide members are connected together and aligned in a predetermined position for aiding the exercising person according to his physical ability. The guide members are connected together by a link which permits varying angular orientations of the members simultaneously or permits varying the angular orientation of one member with respect to the other member. Two sets of wheels and handles are provided wherein the exercising person holds the handle portions which are located between the two wheels. The wheels are dimensioned to run in channels in the flat guide members and are limited in the amount of movement by U-shaped members inserted into holes in the channels. The exercising person moves his arms in and out to move the wheel assemblies along the guide members. As this is being accomplished, the upper portion of the exercising person's body is moved up and down to provide the force necessary for muscle development.
