The height problem is mainly caused by heredity. Of course, a lot of long-term strength training will definitely have a certain impact on height, which can be seen from the general height of strength athletes, such as weightlifters and gymnasts. It is generally recommended to do a lot of strength training in adulthood. A lot of strength training not only has a certain impact on height, but also on the heart. Everyone who has practiced strength knows that general strength training is anaerobic exercise. Without the guidance of professional teachers, people will hold their breath and pay no attention to the adjustment of breathing. After a long time, it will increase the heart load, especially for minors, and even leave some hidden dangers, just like aerobic exercise in a lot of long-distance running. Even famous bodybuilders have heart problems. So it is not recommended that you do a lot of strength training.

As for protein's problem, if it is to grow muscles, we should supplement protein in the right way, such as eating lean beef and muscle breast meat. And even add protein powder appropriately. So the fact that muscles will take it away should not be your concern.
