How to prevent the growth line from appearing in fitness?

The growth line is caused by you practicing too hard, constantly supplementing protein to gain muscle and stretching your skin too fast. The method is to control exercise reasonably, both in quantity and frequency, and do more aerobic exercise. In fact, too much anaerobic exercise is a burden to the body. Of course, if you want to practice hard and don't want to leave dermatoglyphics, it is also feasible. You can buy ointment to prevent aging lines and apply it every day, which actually increases skin elasticity.
