ABSTRACT:
To permit use of a simple physical exercise apparatus by two persons, and eliminate power supplies for forced exercise, a bicycle-type drive system having a bicycle-type frame and a crank is connected over a preferably separable coupling to a movable surface apparatus including an endless running surface, so that one person may exercise by operating the crank of the bicycle-type system and the other exercise by walking, jogging or running on the movable surface type apparatus, driven by the bicycle-type system. Preferably, a support frame, adapted for mounting against a wall, pivotally supports the bicycle-type system for swinging movement to fold the frame thereof against the wall, and the surface-type apparatus likewise is foldable against the frame.
