An exercise apparatus of a push-pull type for exercising a person's abdominal muscles includes a track unit formed by a track board having an upper, body supporting surface extending between front and rear ends; an elongate, track-supporting base board for extending horizontally across a floor; a knee support on the base board adjacent the rear end of the track board; and, a support member for supporting the track board pivotally connected to overlie the base board with the rear end adjacent the base board and the front end at selected elevations. A hand-grip carriage unit with a pair of hand grips and an elbow support aligned rearward of the hand-grips is removably mounted by rollers on the body supporting surface for reciprocal rolling movement therealong. An anchoring unit for a person's legs or hands, alternatively, can be releasably mounted to the front end of the track board, when elevated.

[ I claim:] [1.] An exercise apparatus of a push-pull type for exercising a person's abdominal muscles comprising an elongate track unit comprising a track for extending across a floor and having a front end, a rear end and, a knee support mounted adjacent the rear end; and a hand-grip carriage unit mountable on the track for reciprocal movement therealong so that a user kneeling on the knee support and gripping a hand-grip can perform a push-pull action to reciprocate the carriage between advanced and retracted positions adjacent the front end and the rear end, respectively,the improvement residing in that the hand-grip carriage unit comprises a support configured for receiving a user's elbow or forearm and located rearward of a hand grip so that a user can optionally support his elbows or forearms on the support while gripping the hand-grip during the reciprocal movement to reduce effort required for the push-pull action.
