ABSTRACT:
An exercise device includes a frame having a set of guide links pivotally supported thereupon. Each guide link supports a foot engaging link at one end thereof. The guide links are reciprocated back and forth by a set of intermediate links which engage a set of cranks which rotate about a second pivot point. A control link joins the foot link to the intermediate link and operates to vary the angle between the guide links and the foot links, as the guide links reciprocate. This device provides a very natural running and stepping action for a user who is positioned on the foot links.
