Is there a limit on the number of times minors jump rope?
There is no limit to the number of times minors jump rope. It depends on everyone's physique. You can rest at any time when you are tired of jumping. Half an hour 1200 times, 40 times per minute, 0.7 times per second, a strong child can bear it. If a sick child is weak, he may not be able to stand jumping for a few minutes.
