ABSTRACT:
A standing single leg press exercise machine is comprised of a single movable step arranged to move up and down along an inclined path for exercising only one leg at a time. A resistance mechanism is connected to the movable step for providing resistance to movement. Two stationary steps are positioned on either side of the bottom position of the movable step. Hand rails are also positioned on either side of movable step. A shoulder pad is positioned above the movable step. A method for using the leg press is comprised of standing on one of the stationary steps with a stationary leg, and repeatedly operating the movable step up and down with an active leg. The active leg is exercised until it is tired, and the legs are switched to exercise the previously stationary leg while the previously active leg is rested.
