The treadmill further includes a latch attached to the up-right support adapted to connect with the end of the gas spring which is attached to the track bed. The latch may, preferably attach to a rod, which extends from the track bed and is attached to the gas spring. An incline motor attached to a middle portion of a frame retracts or extends a motor tube.
