It can be clearly felt that modern people's fitness concept and demand are stronger than before. Even many people will ask personal trainers to help them do sports training. On the one hand, it is to keep fit, but often more people choose sports, such as running, in order to keep their bodies in a very youthful and energetic state.
Going to the gym, first of all, is the training and growth of your physical fitness. Second, after a day's work, there will definitely be some negative emotions, which can be effectively released through exercise. The third and very potential benefit is that in the gym, you may have some interactions, which are outside your usual work circle. It's like changing your brain. And changing the brain is very helpful to relieve fatigue.
In addition, some conversations with friends, coaches or strangers in the gym will also make you feel better. I once heard a friend say that one day she went to the gym and there was only one person in it. As soon as she stepped in, the man greeted her, and then she returned a hello, which was as simple as that, and it was a greeting from a stranger, which gave her a good mood all day.
As far as my own personal experience is concerned, when I feel depressed or tired, going out for a run will bring a very comfortable and refreshing feeling after sweating.
