You worry too much. For girls, it is good to learn ballet, which can not only lose weight and shape, but also improve their temperament and quality. Age is not an issue. It is no problem to learn some amateur ballet basics or ballet figure, but the basic skills may require the flexibility of the body. After all, the practice of basic skills is generally started from an early age, and the child's body is soft and the bones are not long, which makes it easier to tear apart. . . But the problem is not very big, there are no special requirements, and you don't have to worry too much about your health. Just have a positive attitude and improve your temperament. . . Even walking will become beautiful after learning this! If the weight belongs to the standard, it is not very fat. Please, you can definitely suggest that you can teach yourself yoga. It is also very good, especially to lose weight, but the requirements are very soft!
