Abstract: This is a multiple function exercise device that enables simultaneous exercise of several muscle groups. The device includes a chest pad that is stationary to the support frame and a seat that moves in a path of motion that enables the user's chest to remain on the chest pad as the user's legs are extended, thereby causing movement of the seat.
