An exercise device is provided which is used in exercising of the abdominal muscles as well as in exercising the muscles of the upper torso, shoulders and arms while the back of the user is supported, elongated and stretched. The device includes a platform which is elevated at one end from a supporting surface for the device. A seat is located at the one end of the platform and a bowed back support member is disposed on the platform adjacent to the seat. The support member presents a convex curved surface of a longitudinal extent such that the back and head of the user can rest thereon with the user in a backwardly reclining posture. A resilient belt fits around the waist of the user while a restraining arrangement preferably in the form of flexible restraining members is adapted to engage the arms of the user during movement of the user from the backwardly reclining posture wherein the back of the user rests against the convex curved surface to a sitting position. The restraining arrangement thus increases the force that must be exerted by the abdominal muscles of the user in carrying out this movement.
