Abstract: An exercise device for strengthening the abdominal muscles and the arm muscles of a user, comprising a T-shaped, tension loaded press bar that selectively telescopes within an elongated shaft when pressed by the hands of the user. The press bar is mechanically linked to the shaft by a stretchable band having an equilibrium relaxed conformation and also having a stretched conformation. When the user presses down upon the press bar, this causes the press bar to substantially retract into the shaft and simultaneously causes the rubber band to be stretched from its relaxed conformation, thereby simultaneously exercising the muscles of the user. The exercise device may be selectively folded upon three hinges, thereby providing an exercise device that is easily carried, shipped, and stored.

Abstract: An exercise device for exercising the abdominal muscles, the back muscles, and the arm muscles of a user. The exercise device comprises a rectangular tubular frame having a seat pad. The frame has a right-angled pull bar assembly pivotally affixed thereunto. The pull bar assembly has a neck/head support pad. In use, the user places the frame of the exercise device upon an existing horizontal support structure, and lies down upon the device, with the buttocks of the user supported upon the seat pad, and the upper torso and head of the user supported upon the neck/head support pad. The user grasps a horizontal crossbar of the pull bar assembly within the hands of the user, and pivots the crossbar downward, thereby causing the neck/head support pad to pivot upward, and thereby elevating the back of the user above the horizontal support structure and making it easier for the user to do a number of sit-up type exercises.
