A device designed for regaining the health of survivors from apoplexy, heart attack, poliomyelitis, accident and aged people by doing exercises. An adjustable-speed motor drives a pair of pedals so that the user's arms or legs can be hauled or dragged gently and regularly to move roundly with the user's arms or legs directly connected with the pedals and in turn with the motor or to move to and fro, up and down by a pair of wires which through a frame changes their direction, as controlled by the pedals.
