Yes, don't believe it. Try to jump 200 times first, and you will feel a little hot and short of breath immediately. Unlike running for a long time, I have no feeling in my upper body. Jumping rope feels all over, and you can lose weight quickly. You can grow taller, too, because you have been jumping. Eat more and eat less for dinner, just pad your stomach. Drink more sleep at ordinary times to speed up metabolism, so that you can lose weight faster.
