Abstract
A treadmill with an endless belt forming a movable surface to walk or run on. The novel supports for the endless belt suspend it from the periphery of its uppermost surface. Two large rollers within the endless belt suspend it and allow it to be moved longitudinally. Two banks of small rollers mounted along the top edges of the frame form the lateral supports. These rollers engage the edges of the endless belt to suspend it laterally within the exercise area.
