Abstract: An elastic cable having stirrups fixed to each end and an elongated bar having ends that receive a central portion of the cable and hold the stirrups separated one from another during use. Each end of the bar is provided with a U-shaped yoke that guides the cable from the bar. The yoke guide is provided with projections that retain the cable in the guides, particularly when the cable is slack. Opposed lugs also project from the bar ends such that cable wrapped circumferentially about the bar ends for tensioning the cable are prevented form slipping off the ends of the bar during exercise. The bar end is also provided with receptacles having surfaces that engage the stirrups to secure the stirrups in frictional contact with the bar, particularly useful for some exercises. Additionally, the exerciser includes an improved door attachment device that greatly improves the versatility and usefulness of the exerciser.
