Abstract: A door or partition mounted exercise device for exercising muscles of the arms and upper body. The device includes an exercise portion attached to a mounting apparatus. The exercise portion is composed of a pair of parallel lateral support members extending perpendicularly from a centrally located transverse positioning bar. A pair of beam members extend perpendicularly downward from the lateral support members when the exercise device is in a vertical position. A pair of lower support legs extending perpendicularly from the beam members in an orientation parallel to the lateral support members. The mounting apparatus is a pair of parallel members upon which the transverse positioning rod can be affixed. The upper ends of the parallel members are formed into hooks which can be mounted over the top of a conventional door. The lower end of the parallel members extend perpendicularly outward to form projections extending into the terminal ends of the lower support legs opposing the beam members.
