ABSTRACT:
A grip assembly for a jump rope includes a grip body having a first end formed with an open casing and a second end formed with a receiving space, a counter mounted in the casing, a cover mounted on the casing and abutting the counter to locate the counter between the casing and the cover, a pivot head rotatably mounted on the casing and connected with the counter to drive the counter, and a weight member mounted in the receiving space of the grip body. Thus, the counter can count and indicate the jump number of the jump rope so that the user can know the jump number exactly. In addition, the weight member provides a damping force to the user' arms so as to exercise the user's arms.
