Abstract A door mounted exercising device which is to connect with the bottom edge of a door with the door being located in a closed position with respect to the door jamb. The exercising force is to be transmitted through the door against the door jamb. The exercising device is attached to the door by means of attaching bracket assembly which is removably secured to the door. The exercising device includes a tube within which is located a coil spring. The tube is removably connected through a pin and slot assembly to the attaching bracket assembly. The spring is mounted about a rod which is positioned within the tube. A portion of the rod extends exteriorly of the tube and is attached to a graspable handle assembly. The handle assembly is capable of being pivoted relative to the rod.
