How do teenagers exercise healthily?

You can play all kinds of sports that teenagers like (some like playing ball, some like swimming, and some like jogging). I personally recommend swimming, which is good for all functional organs of the human body and can cultivate the coordination of the whole body. This is a good exercise. Choosing exercise is only one aspect, and I think the most important thing is persistence. Persistence is the key, no matter what sports, we must persist. Persistence can produce results!
