1. Hand throwing skills: feet are parallel to shoulder width; Raise your arms to shoulder level, and then lower them naturally. When you continue for the fourth time, your arms and knees will be driven at the same time.

2. Cross-stroke: The knee naturally shakes up and down, like a flat swing. You should turn around, relax your shoulders, swing your arms from side to side like rattles, and beat your legs. Don't hit hard, lest you hurt yourself.

3. Squat: Do squat leg exercises often, 30~40 times each time, and then gradually increase the number. This kind of exercise can burn fat and reduce the cholesterol content in the blood at the same time.
