Whether it's appropriate or not depends on what you think. Everyone goes to the gym for different purposes. For example, I go to the gym, mainly to exercise. I want to make my body better, because the atmosphere of doing exercise in the gym is better, otherwise I have been doing exercise very lax. Others may go to the gym for other purposes than fitness, such as having an affair at the gym. Whether it is suitable for marriage or not depends on the performance of the other party. Generally, if they do something behind their backs that is not specific to their feelings, they can be found through subtle observation. Besides, you can go with her, so that you can know whether it is suitable for marriage or not. Time will explain everything, especially feelings. If you can't stand the test, you might as well leave early. I have to admit, some little brothers or sisters in the gym are really attractive. No matter from the face value, figure or temperament, they will definitely attract some opposite sex, and some people will contact them. If they are loyal to their feelings, there will be no fluctuation in their hearts. If you can't stand the temptation, you may do something bad for your feelings, such as cheating, or even cheating, so being in the gym is a test of one's concentration. However, I believe that many people go to the gym mainly to exercise. In today's society, people's own health is becoming more and more important, life is endless, exercise is endless, and they are uncomfortable all over. The purpose of their going to the gym is simple, that is, for better figure and health.
