ABSTRACT:
Foot treadle operated exercising apparatus of this invention provides for transfer of air from one foot treadle operated vertically disposed bellows to another through a restricted pathway adjustable in size by an adjustable valve to select a desired work load. A stroke length adjustment is featured for changing the length of the stroke. This is achieved with bellows that are biassed to return to an extended condition in the presence of atmospheric air. Thus with a closed air system, a manually operated air admission and venting valve will increase the bellows height when opened to admit atmospheric air and will decrease the bellows height when opened and pedals are depressed to vent air. The foot treadles are operable from a standing, sitting or lying position. An auxiliary arm exercise harness operates in conjunction with the foot operated treadles by means of hand manipulated lines cross connected so that the left hand will depress a right foot treadle and visa versa. The entire work load is effected by the transfer of air from one bellows to the other when the treadles are operated in a riding, jogging or climbing action. One embodiment provides for bicycle riding type of exercise activity.
