ABSTRACT:
This invention is a skipping rope comprising a flexible cord and a pair of handles secured on the cord and defining there between an effective cord length wherein at least one of the said handles on the cord is an interference fit in the opening of the handle so the effective cord length is adjusted by moving the handle assembly along the cord member and is maintained by the interference fit between the cord and the opening in the handle. Movement of the handle is performed simply by applying tension between the cord and the handle so the user, by moving the handle in one direction or the other, may find an effective working cord length that most suits them.
