Abstract
The present invention provides an exercise device that generally includes two treadles pivotally connected with a frame so that the treadles may pivot up and down about an axis. Each treadle includes a tread belt that provides a moving surface like a treadmill. Each tread belt is supported by a front roller and a rear roller, which is common to both treadles. The treadles are interconnected to provide an alternating upward and downward movement relative to each other. Opposing end portions of the rear roller are rotatably supported at the rear end of the frame. Outer sides of rear end portions of the treadles are rotatably supported by the outer end portions of the rear roller, and inner sides of rear end portions of the treadles are coupled with the frame through an inner support structure that defines a virtual pivot.
