ABSTRACT:
A jump rope handle having a ball bearing about the end of the "rope" inserted in the handle in which the opposite sides of the bearing outer race are held between a flange and the exercise weight which in practice has been found to cause a spinning mode in the inner race which generates a greater rope-turning speed during exercising use of the jump rope.
