ABSTRACT:
An exercising machine for especially training the muscles of the leg includes a base on which a pair of support tables is rotatably carried, one for each foot, a vertical standard on the base adapted to provide fixed hand grips for a standing user or a seat for a sitting user, and a pair of resistance devices preferably formed by a selectable number of weights. Each resistance device is respectively connected by a cable and pulley system to one of the support tables to provide a variable reactive force as the associated support table is moved out of a neutral position. The seat and hand grips can be set at a selected height, the hand grips can be set at three positions in one horizontal plane, and the foot-supporting portion of each support table can be placed in a selected angular position by which the neutral or starting position is picked. The machine can be used close to a wall.
