I think the most important thing is to attract women, because many men are in good shape, so women will pay attention to him. If it is a fat house, no one will look at him again.

Moreover, many men in the gym go to the gym mainly to chat up some women to show their personality charm. In this way, they can also show their friends how many women they have attracted by virtue of their figure. His friends will definitely want to go to the gym when they see that he has attracted so many girls.

Another reason is that if you have muscles, this man must be confident and look good in temperament and spirit, because there are few men with muscles, and they look better than other men.

Especially some people who practice muscles will have stronger willpower, because they need strong willpower when exercising.

However, there are also many people who exercise muscles for health, because if they are all fat, there will definitely be various diseases, such as high blood pressure and hyperlipidemia caused by obesity, but if they are all muscles, they will look very healthy.

There are also many people who practice muscles for bodybuilding. In this way, they can make a lot of money and become famous.

I think another aspect is following the trend, because now more and more young people realize the importance of fitness, so many men also follow the trend.

But when they go to the gym, they see that many people have muscles. Looking at their small bodies, they have the motivation and want to practice muscles.
