Abstract
A size-adjustable jump-rope exercising apparatus comprising a framework structure having a substantially "H"-shaped configuration wherein the framework is formed having spaced, parallel, longitudinally extended, side-frame members. The frame members are connected together intermediate their free ends by a transverse strut member by which the width of the apparatus can be adjusted and which includes gripping handles whereby the user thereof holds the apparatus for rotation about the longitudinal axis of the strut member when the strut member is positioned in a horizontal mode. Mounted at each free end of the side member is an elongated rod member adjustably mounted longitudinally therein and a flexible rope which is looped across from the outer end of one rod member to the other, defining a closed-loop, jump structure having dual jumping ends.
