1. More exercise can increase yang. Everyone agrees that boys with a special standard figure or 8-pack abdominal muscles will feel very safe, which is a manifestation of westernization to some extent. Maybe those thin and weak middle-aged uncles, or greasy middle-aged uncles, will feel nothing, which may be an influence on the opposite sex.
2. Action behavior, which will also affect others' evaluation of him. Imagine a muscular man with eight abdominal muscles holding orchid fingers and running like a small Shenyang. Does it give people a very uncomfortable or disgusting feeling? This is the external feeling brought by behavior and a manifestation of yang. Very unusual. If a hero saves the United States, does the rescued girl think this boy is very masculine? This is also a kind of temperament guidance brought by behavior.
The sun is more manifested as a virtual thing that gives people an intuitive feeling, just like temperament. No one can tell what temperament is made of, but people know that reading more books can change a person's first impression on others, that is, change his temperament. Doing more exercise is also true for us male yang.
