There are many reasons for obesity, and lack of physical exercise is one of the important reasons. Therefore, physical exercise is a simple and effective means among many methods to lose weight.

The third is to arrange the exercise process reasonably. Before exercise, athletes should have a medical examination to understand their heart function. Each exercise should include warm-up activities and finishing activities, generally stretching activities of sports joints; According to the principle of excessive recovery, exercise 3-4 times a week for 30-60 minutes/time.
