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.
