ABSTRACT:
A hollow hand grip for a jump rope or other similarly-gripped exercise device, in which one or more exercise weights can be used; said hand grip including, specifically for the contingency when less than all weights are used, an end plug which effectively maintains the end wall thereof in its shape and location to correspondingly maintain this end wall in its frictional engagement with the closure for the compartment for the weights defined within the hand grip, thus contributing to the safety in using said weighted hand grip.
