Overwork and excessive fitness will affect the development of bones. It is often said that at the age of bone development, that is, when he is growing up, he doesn't mind doing a lot of exercise or exercise, which will affect the development of bones, resulting in a short stature or a short and lean body. For the original intention of exercise, it is not worth the loss, which will lead to a person's life-long body freeze and eventually become a more normal body.

Moreover, it is often not worth the loss to exercise when you are young, because at this time, a large number of human needs are still for the age when your body is getting fat and your bones are getting taller. Excessive pursuit of strong muscles was often impossible when I was young, and the flow of material to the body and food was not enough to achieve such a fitness effect. Therefore, people who exercise since childhood rarely see it, and the effect of people who exercise like this is very poor.

For fitness, some thin people don't mind going to fitness, because there is not so much basic fitness. They just adjust the original muscle content, reduce fat, show more muscles, and then take in some proper protein, which leads to the body being rebuilt into a more perfect state. But some thin people often have less meat in their bodies, which is difficult to achieve. For body remodeling, it is difficult to achieve without such a foundation.

So fitness is also conditional. If your exercise ability and physical condition don't allow it, then you don't mind going to fitness, which will affect your health. You often don't go to fitness at a very young age, because you will miss the age of physical growth and bone development, which will lead to the loss, and ultimately fail to achieve the effect of fitness.
