Don't touch the snacks you should eat and the cola soda you shouldn't eat! Drink more milk but exercise every week! You can also exercise two or three times a day. The amount of exercise should not be too small, seven or eight hours a week, or about an hour and a half a day. In short, you can allocate time to run, play ball, swim and jump rope. Playing ball is a good sport. You can grow taller and lose weight! Because there are many jumps.
