ABSTRACT:
An exercise device includes a frame, a pair of foot supports, and at least one four-bar linkage assembly coupled to the frame. The at least one linkage assembly is coupled to at least one of the foot supports. The four-bar linkage assembly directs the foot support in a generally elliptical motion while in use. The generally elliptical motion defines a major dimension extending at an angle from horizontal that is within the range of about thirty degrees (30°) to about seventy-five degrees (75°) and the major dimension having a length that is within the range of about ten inches to about eighteen inches.
