Abstract: An exercise machine with a seat and two adjustable cranking mechanisms is disclosed. The first cranking mechanism has rotatable hand grips for grasping by the user's hands while the second cranking mechanism has rotatable pedals for engagement by the user's feet. This second cranking mechanism is located at a position vertically above the location of the seat. Therefore, the exerciser may not use his or her body weight when exerting pressure on the pedals. This machine exercises virtually all of a user's muscle groups, however, the configuration of the seat vertically below the second crank mechanism results in a particularly strenuous activity for a user's hamstrings. Additionally, each cranking mechanism is selectively adjustable to a plurality of exercise positions. This makes the machine adaptable to all exercisers regardless of their size and shape and permits the user to selectively vary the exertion required during the exercise.

Abstract: The provision of power by the human body to bicycles, tricycles, exercise equipment, wheeled chairs or the like is effected using a hand-operated lever (35) and/or a pair of pendulums (23). The hand-operated lever is pivoted about an axle (33) on a frame (12) of the cycle or other equipment. Rotation of the lever about that axle in either direction causes a respective sprocket wheel (38) to rotate about an associated axis, with consequential rotation of a rotatable member (14) which drives the cycle or other equipment. A tensioning or recoil mechanism (40,42) returns the sprocket wheel or drum to its original position when the lever is rotated in the opposite direction about the axle. Similarly, forward movement of a pendulum about the axle (22) from which it depends causes an associated different sprocket wheel (28) or drum to rotate about the axis to cause the rotatable member to move and drive the cycle or other equipment.
