A compound exercise apparatus for extension, stretching and rowing-type exercises where the user's body weight provides a component of the resistive force against which the user exercises. The apparatus includes a base having a pair of stationary foot pedals, a cushion mounted to the top of a support bar for supporting the user's upper body. A lower end of the support bar is mounted to the base and an upper end of the support bar is pivotally mounted to an upper end of a twin-wheeled push rod. The twin-wheeled push rod is biased to a retracted position by an extension spring anchored within the support bar and connected to a cable anchored to a connection post of the twin-wheeled push rod. A fork member having a U-shaped bar at a lower end and a T-shaped connection member at an upper end is pivotally connected to the connection post of the twin-wheeled push rod. A lower end of the U-shaped bar of the fork member is pivotally connected by a linkage to the support bar. The linkage is pivotally connected to a restoration spring that also biases the push rod and support bar to a retracted position. A first end of a handle arm is pivotally mounted to the T-shaped connection member and a second end of the handle arm is releasably connected to the lower end of the U-shaped bar. The handle arm is selectively positioned by the user for the desired exercise. The base is selectively pivotable relative to the support bar so that the apparatus may be folded for storage.
