ABSTRACT:
The application of a specific ball-bearing swivel which houses several ball-bearings, between the handles and rope material of a jump rope including a threaded member on the cap end and an O-ring on the spindle end will virtually eliminate the friction and drag associated with a conventional jump rope and allow free rotation of the jump rope material while attached to the handles.
