First of all, this is my other answer, which indirectly answers the appearance change brought by fitness. Long-term fitness can change your appearance. The answer I gave is yes, which is a kind of heartfelt confidence. Only when the heart is really strong can we reflect the beauty brought by self-confidence. Exercise and fitness can bring you this magical power. I don't know which factor of the body is at work, dopamine. I'm not sure about that. But every time I run and lift the iron, I strut. I feel that the whole world is being trampled under my feet, even though I am sweating. Sweating all over. Ha ha ha ha ha. Therefore, the benefits of long-term fitness are not only in appearance, but also in mind. Of course, there are also physical and visual changes, such as the face and figure with a full face, which look bloated. Fat. But a body with proper muscles looks tight. Orderly.
