AbstractA compact, elliptical exercise device includes a pair of primary foot links, and a pair of corresponding auxiliary foot links. A first end of each primary foot link is coupled to a pivot axis so as to move in an arcuate path. A second end of each primary foot link is connected to a guide assembly, which constrains it to travel in a reciprocal path of motion. A first end of each auxiliary foot link is coupled to the guide assembly at a connection point spaced from an engagement point at which its respective primary link is connected. Each auxiliary link is slidably supported by a respective one of its primary foot links so that a second end of each auxiliary foot link will travel in a reciprocal path along the primary foot link.
