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.

Treadmill apparatus comprising:
- first and second adjacent treadmills each having a continuous tread, and first and second ends;
- a frame pivotably supporting the first ends of said first and second treadmills;
- first and second spring means for supporting the respective second ends of said first and second treadmills in a first position above a supporting surface;
- and
- first and second resistance means for resisting downward pivoting movement of said first and second treadmills from said first position to a second position as a user's weight is placed upon said treadmills, said first and second spring means returning said first and second treadmills from said second position to said first position when said user's weight is removed from said first and second treadmills, said first and second treadmills alternately pivoting up and down about said first ends as a user treads thereon.
