ABSTRACT:
An exercise device consists of a frame having an upright support member, upper and lower pivot levers pivotably mounted on the support member, first and second foot platforms pivotably mounted on the first and second end portions of the lower pivot lever, hand grips mounted on the first and second end portions of the upper pivot lever, and a resistance cylinder connected between the corresponding first end portions of the upper and lower pivot levers. The upright support is vertically adjustable to adjust the vertical height of the upper pivot lever. In use, the operator stands on the foot platforms, grasps the hand grips of the upper pivot lever, and reciprocates the feet and hands in a rocking, or see-saw type motion similar bicycling, rock climbing or stair climbing. The resistance cylinder comprises a hydraulic-type cylinder which provides resistance during reciprocating movement of the upper and lower pivot levers. In a second embodiment, separate resistance cylinders are respectively attached between the lower pivot lever and the frame, and between the upper pivot lever and the frame. The separate resistance cylinders provide independent adjustment of resistance for both the upper and lower body. By maintaining one of the upper or lower pivot levers in stationary position, the user can independently operate the other lever for an isolated upper or lower body workout.
