ABSTRACT:
A treadmill device includes a frame, and two side-by-side treadmills each having a continuous tread and first and second ends. The first ends of the two treadmills are pivotably supported on a base portion of the frame by a roller shaft which extends through the treadmill rollers. The second ends of the treadmills are independently supported by spring return hydraulic cylinders which are connected between the treadmills and spaced support members of the frame. The continuous treads are driven by a motor which is coupled to the roller shaft. The treadmills alternately pivot up and down as a user walks thereon.
