Abstract
Abstract A jump rope has tubular handles, each configured with a deeply set annular recess at one end to provide a bearing surface for receiving the knotted end of the rope, and a bell shaped curvilinear egress port at the opposite end on the handle adjacent to which is strung on the rope a substantially spherical bead for preventing jamming of weighting links on the rope into the handle.
