No, fitness is good for your health, but it should be moderate. If you happen to be growing up, you'd better not do strenuous exercise, such as squat. These high-intensity exercises can easily make your bones strong and explain, and then may affect your height.

Just stick to a certain time at a fixed time every day, mainly through various ways to bless and exercise together. At first, I advised you not to exercise with equipment, such as; Push-ups, pull-ups Now I can do 35 push-ups and 25 pull-ups with one hand. Just stick to it anyway, hehe.
