How to exercise is the healthiest?

It is necessary to get up and run every morning. You need to jog 10 minutes or so, and stretch for 5 minutes before exercise. The rest time between exercises in each group should not be too long, generally between 40 seconds and 50 seconds, and the rest time for heavy-load and high-intensity exercises should not exceed 3 minutes. Too long rest time will affect the exercise effect.
