If you are not particularly fat, don't do such strenuous exercise. First, it is difficult to persist. Second, such strenuous exercise is easy to rebound if you lose weight. Set yourself an appropriate amount of exercise and just stick to it. I'm so thin, about 5 kg a month.

The best time to jump rope is from 3 pm to 9 pm, and it doesn't matter when the hula hoop is.

Just jump/kloc-0.000 times a day. Remember to stretch before jumping.
