Abstract
An exercise device is provided including a foot link having a rearward end and a forward end. An adjustable stride mechanism is provided. The adjustable stride mechanism includes a primary gear and a secondary gear. The primary gear is sized larger relative to the secondary gear. A primary crank connects the primary gear and the secondary gear. A timing belt connects the primary gear to the secondary gear. The primary crank and the timing belt enable the secondary gear to rotate around the primary gear. A secondary crank is pivotally attached to the secondary gear and to a foot link. The secondary crank creates an ellipse-shaped path for the foot link as the secondary gear rotates around the primary gear. Thus, the foot link motion combines an at least a dual ellipse motion. An automatic adjusting mechanism can be provided to adjust the adjustable stride mechanism.
