Abstract: A device for promoting health and rehabilitation through exercise by way of providing motion to one's legs. The device comprises a frame, with a motor secured to the frame. An axle extends outwardly from the frame to either side and is powered by the motor for rotation about a horizontal axis. The axle drives a pair of crank arms to the free ends of which are secured pedals. The pedals are adjustable so that their axes of rotation are adjustable with respect to the axis of rotation of the axle. Straps or the like associated with each of the pedals to releasably secure a user's foot to the pedal. A flexible leg support strap extends from a portion of the frame. In operation, an end of the strap is wrapped around a leg just behind the knee. The strap is of a length and is positioned so that the leg is free to move as the pedal rotates with one's foot strapped to the pedal while sufficient force is provided by the strap on the leg to prevent unwanted lateral movement of the leg.
