I can set myself goals, such as: I will jump 500 times today, and then I will try to jump twice, that is, 250 times each time, and I will try not to break. The rest time between two times is about 2 or 3 minutes. You should not jump too fast, because it takes 20 minutes to burn fat. If you jump too fast, you will be careful to thicken your calves. I jump three times a week, and I can increase my exercise after a while, 500 to 700. From 700 to 1000, from 1000 to 2000, it may be boring. You'd better find a partner to dance with or listen to music to distract you. After dancing, you should go to leg press and leg press to exercise. At the beginning, the next day after dancing, I feel my legs are sore and I can't even bend my legs down the stairs. You should do more massage to relax your legs.
