So it's the same thing to do sports. No one really loves sports, and there are some reasons for them to keep exercising. These reasons can be roughly divided into three types. Let me give you a brief introduction.
The first is to exercise for health. Many people are forced to exercise because of health problems. Some people insist on exercising because they are afraid of seeing other people's health problems, although there are no health problems. This is also human instinct, because no one is not afraid of death and wants to live one more day, so they can keep exercising.
The second is for ideals and goals. Some people exercise to lose weight and make themselves more beautiful, so that they can put on beautiful clothes and get more attention. For example, more men or women like themselves. For the ideal, they usually like some sports, such as basketball, football, badminton, table tennis, track and field, swimming and so on. They may have an idol in their hearts who is the champion of this sport, because they want to be like idols.
Besides, there are some people working, such as fitness coaches, athletes and stars. In order to maintain their image or make achievements, whether for national honor or money, they have a belief that they can keep exercising. I think people who can keep exercising are basically the above three types.
