Exercise needs persistence, but you can rest for a day or two occasionally. The exercise time can be in the morning and evening, preferably from six to seven in the morning. The length of exercise depends on your physical condition, generally controlled between half an hour and an hour. Exercise content is varied, such as running, leapfrog, sit-ups, push-ups, gravity upward or skipping rope, playing basketball, badminton and so on. At the same time, pay attention to sleep (generally controlled in eight hours, but also a little more. ) and diet (nutritional balance).
