Abstract
An exercise device includes a frame which supports a pair of foot links so that a first end of each foot link is pivotably coupled to the frame for motion about an arcuate path. A guide which is supported by the frame engages each foot link and directs a second end of each foot link along a closed, curved, generally teardrop shaped path of travel. This combination of motions defined by the foot link provides a natural running and stepping motion in which the heel of a user's foot initially rises faster than the toe as the foot move begins to forward and subsequently falls faster than the toe as the foot begins to move backward.
