First, fitness can enhance physical fitness. Men will not be strong easily if they don't exercise. Weakness is actually very unmanly. Fitness is not about turning yourself into a muscular man, but about having a strong body, giving the beloved woman a sense of security and not being bullied. This is really important. And the body will be much better after fitness. Many girls like men with good figure, either too fat or too thin. Boys with a little muscle are really attractive.
Second, the man is the head of the family. Fitness exercises a person's willpower and makes him more capable of shouldering the responsibilities of a family. If you really want to exercise, you can avoid obesity and avoid the harm of "three highs". After fitness, the whole person will be more energetic and physically better than those who stay at home.
Third, the face value is not enough, and the figure is together. He has a reason. Ugly and fat men will be rejected.
