  • Publication number: 20050227827
    Abstract: An exercise device adaptable for exercising that utilizes both a weight and rope friction to provide load resistance is described. Preferred embodiments of the exercise device are adapted for use in conjunction with a doorway and an associated door. By selectively wrapping a rope, which is connected to the weight on one end and a grip on the other, around a cylindrical member, the effective load experienced by a user pulling on the handle is multiplied many times in excess of the weight's mass. By removably attaching the exercise device to the door and the doorway, no additional framework is required thereby making the device relatively lightweight and compact.

  • Publication number: 20050221964
    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.
