If you are a boy, you can consider running or playing basketball. My brother ran three kilometers every night for two months, and the time was reduced from 160 to 140. However, you must insist that you can't eat after running. If you are a muscular girl, don't try to run two or three times a week, sit-ups 50~ 100 times, and jump rope step by step, so as not to hurt your health. You can also lose weight, but you can also shake the hula hoop to prevent your chest from sagging, but you should also pay attention to what you can do. Don't hurt your health because of excessive exercise. But be sure to pay attention to your diet and don't eat within 3 hours before going to bed, otherwise all your efforts will be in vain. If you really can't stand it, you can drink a glass of milk before going to bed, which will not gain weight but also help you sleep and beautify. I wish you success!
