Abstract
Abstract An exercise apparatus includes a stand having an upright support and a base. User engagable members are mounted on the upright support for the user to exert a force thereagainst. A scale is mounted on the base of the stand to support the user and to measure the force exerted by the user against the user engageable members. A display is connected to the scale to provide a visual indication of the force measured by the scale. In one embodiment, the user engagable members are movable vertically along the stand in a controlled manner at preselected speeds, direction and length of travel. The user engagable members are also movable in a controlled manner transversely with respect to the stand at predetermined speeds, directions and lengths of travel. A pair of scales are alternately mounted on a trolley which is movable vertically along the stand to measure the upward and downward forced exerted by the user on the user engagable members.
