Abstract: A door mounted support apparatus for a punching bag having two main components: (1) a main support bracket; and (2) a punching bag support bracket. The main support bracket includes a first horizontal bar and a second opposite side horizontal bar. The first and second horizontal bars are connected via two parallel curved arms. The main support bracket is mounted to a door frame by extending the first horizontal bar in front of the side door jambs and hooking the second horizontal bar behind the top door jamb. Adjustable clamps on the curved arms and on the first horizontal bar are used to tighten and secure the main support bracket to the door frame. The punching bag support bracket is then inserted into slots on the first horizontal bar and locked into position with locking pins. A punching bag is suspended from the punching bag support bracket.
