US 6,206,394 B1 · Health exercise equipment propelled by simulated rowing motion

Abstract

An exercise apparatus to exercise the upper and lower body that is powered by a simulated rowing motion is described. The exercise apparatus includes a frame, front and rear wheels, a slide rail, a lever arm, a steering mechanism and a drive mechanism that translates the user's energy to propel the exercise apparatus. The rotation point of the lever arm, the fulcrum of the lever arm, the maximum distance the lever arm travels fore and aft, and the length of the lower portion of the lever arm, among others is adjustable to maximize efficiency or effectiveness of exercising the user's upper and lower body. Stabilizing members are attachable to the rear wheel axle, wherein the stabilizing members are adjustable to either elevate the rear wheel above the riding surface or provide stabilization to the extent required by the user.
