ABSTRACT:
An exercise machine for exercising the forward and backward muscles in the upper and lower muscle groups. A first bidirectional exercise unit is attached to a frame to permit stand-up pedalling against resistance. A second exercise unit is attached to an upstanding vertical section of the frame, and is of adjustable height so that the person who is standing and pedalling on the lower exercise unit may adjust the upper unit to the height of his hands or to a height at which certain muscles may be conveniently exercised. To promote the optimum exercise of certain muscles in the lower muscle group a shank of which produces a significant but yielding resistance to the forces of the body weight and muscular activity of a person pedalling in a standup position is provided for the first bidirectional exercise unit. The upper and lower muscle groups may be exercised in synchronization or at will.
