/kloc-I didn't know it in 0/989. One of our childhood toys was also a sports tool, a circle, a thread and a ball.
I know ... hehe ... if the ball is stuck in the leg and the other leg is lifted from time to time to let the rope go around, it should not be sold now. Suggest a way to lose weight, hula hoop and skipping rope are all good choices ... keep childhood memories and turn them into beautiful memories ... I hope they can be adopted.
