I once saw a video introduction that a habit is basically fixed after you stick to it for more than a month. I did something for a month, and now I'm doing it intermittently. I dare not say that it has greatly changed me, but it has made my boring life more interesting than before.
Keep running and do sit-ups every day during the winter vacation. I think it has obviously improved my physical condition. I insist on running every day because I like going out to play, and then I like walking. But every time I go out, I get tired after a short walk, and I will be particularly tired the next day, so I can't make the next stop perfectly, so I run and exercise.
After returning to school, I still insisted on doing yoga. The purpose is very simple, that is, I want to make a dynamic in my circle of friends. I also have a vest line, what a pure purpose! About half a month! Later, when I was busy with my internship, I stopped doing it. Although there is no vest line, there is no fat on the stomach. With fitness, my complexion has also been greatly improved, but now I am busy with work, and I am depressed again, missing the relaxed days at school.
