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. This combination provides activation of the leg and hip extensor muscles and the trunk flexor muscles at the same time. In another embodiment, a resistance arm is added that is pivotally attached to the frame and mechanically linked to the seat, thereby causing movement of the arm as the seat moves. This allows the additional activation of the triceps muscles, or elbow extensors of the upper arm, while also working the leg and hip extensor muscles and the trunk flexor muscles all in a single movement. The advantage to such a movement is the time saving effect of working a large group of muscles at one time as opposed to several exercises one after the other.
