First of all, if punching in for fitness is just to compare with friends, or just to show off in a circle of friends, it is not punching in for fitness, nor is it self-deception. The real purpose of fitness punching is not whether others know or not, but whether others care. Fitness affects our own health, and only through sweat can we get a healthy body. You can't get anything just by punching in self-deception, and even increase others' misunderstanding. Obviously, daily exercise, what kind of body shape it is, will make others think.
However, if you want to punch in and supervise yourself because of poor self-control, it is not self-deception. If there are difficulties, we should try to solve them. Poor self-control is a common problem of most people, but as long as we stick to our own way, we will still succeed. To a large extent, we want to keep fit through the supervision of others, which is not shameful, let alone cheating.
Of course, there are many other ways for us to keep fit: First, if economic conditions permit, we can find a personal trainer to guide and accompany us in fitness; Second, pulling three or five friends or friends of the opposite sex to exercise together can not only draw closer to each other's feelings, but also play a fitness role; Third, forcing yourself to participate in some social sports can not only play the role of exercise, but also keep yourself going.
