ABSTRACT:
An exercise device for working one's arms or legs is disclosed. The exercise device includes a crank assembly with a stationary frame and a rotating crankshaft attached thereto. The crankshaft is fitted with either handgrips or shoe plates to which an individual's arms or feet may be attached so that the individual's limbs may be worked. A motor unit with a drive motor is selectively suspended from the crank assembly frame. Complementary couplers on the crankshaft and motor unit interlock when the motor unit is attached to the crank assembly so that power from the drive motor can rotate the crankshaft. The exercise device can thus be used by individuals capable of manually rotating the crankshaft, or by individuals who would benefit from having their limbs worked but require assistance in rotating the crankshaft. The handgrips and shoe plates are each provided with a bearing assembly that allows them to rotate about the crankshaft and which is releasable so that the handgrips and shoe plates can be interchanged as may be desired.
