Abstract
Abstract A jump rope includes a flexible line having a pair of handles attached to the ends thereof for being grasped by the hands of the user. A flexible hollow member is disposed on the line, and is attached to the line for fixing it thereto midway between the handles so that as the user is skipping rope, the flexible hollow member engages the ground to facilitate the continued skipping operation. The handles are hollow, and small particles are disposed within the handles and within the flexible hollow member to provide a rhythmical rattling sound as the user is skipping rope.
