Question

How Exercise Burns Fat

　　The kind of exercise that reduces fat is called aerobic exercise（增氧健身法）. Aerobic exercises have walking, running, swimming, bicycling. During aerobic exercise, the heart beats faster and breathing is heavier. The more oxygen you breathe in combines with fat and slowly bunts the fat away. Aerobic exercise (20 to 30 minutes of exercise three or more times a week) also raises the body’s metabolism（新陈代谢）; the body bums more calories（卡）all the time?--even at rest!

How Much to Exercise

　　To improve health and bum fat, people should exercise 20 to 30 minutes three to five times a week. Most children usually have no problem finishing this since their activity levels tend（趋向）to be higher than adults. But if your children, or perhaps your whole family, are over weight, they may need more exercise. This means aerobic exercise?--faster heart rate, increased breathing, muscles working. Don’t let your children or yourself overdo it. A good rule is the talking / singing rule: if they are breathing too heavily to sing, but can still talk, the intensity（强度）is just about right.
