Abstract: A housing has an upper cover, a bottom, front and rear faces, and parallel left and right side faces. The height of the rear and side faces between their top edge and bottom edge is less that the height of the front face between its top edge and bottom edge. Laterally spaced parallel guiding slots are formed in the upper cover. A pedal mount extends through each of the guiding slots and is attached to an associated left or right pedal. A glide rail beneath each guiding slot has an upwardly facing recess slidably receiving a lower extent of one of the pedal mounts. A motion imparter includes corner pulleys. A cable in a closed loop configuration is trained around the corner pulleys and is attached to the lower extents of the pedal mounts to move the foot pedals in equal and opposite directions during use.
