There are many girls who don't really need fitness to improve their figure. They just want to show off their figure by taking photos in the gym, tell the people around them how good their figure is, and then send it to a circle of friends to enjoy the praise of their friends.
There is another kind of person who may really want to go to the gym to exercise, but because he is lazy, he doesn't want to exercise after entering the gym. In order to make this trip to glad you came, it is a psychological comfort to take a photo in the gym to show that he has come to exercise on time.
Therefore, if we meet girls who only take photos but don't exercise in the gym, we don't need to pay attention, because fitness is a self-disciplined behavior, improving their figure and enriching their inner self-confidence. However, we don't need to pay attention to those who encounter these performance arts and just want to send photos in the circle of friends and enjoy the praise of others.
