ABSTRACT:
Accordingly to one embodiment, an exercise device comprising a T-shaped cylindrical member with an associated mounting assembly that permits the device to be removably mounted to the edge of a door and utilized when the door is closed is described. When an elongated rope with handles at its ends is wrapped around the T-shaped cylindrical member in the desired configuration, a significant amount of resistance to movement of the rope is provided. In one preferred form of exercising using the device, the exerciser provides a small counter force to the handle being held by the arm that is not being exercised and the resulting force necessary to move the handle and rope with the arm being exercised is a much greater than the small counter force as a result of the multiplier effect of the wrapping of the rope around the T-shaped cylindrical member.
