If I don't stick to this way of losing weight through exercise, I will definitely rebound, so I will stick to it anyway, and losing weight is a long way to go, so if I have to, I must stick to it and then I won't lose weight, so it's easy to rebound. Here, it is unreasonable to lose weight only through exercise, that is to say, you need both exercise and diet to lose weight more effectively. After you stop exercising for a day or two, if your diet is properly controlled, the rebound effect will not be so great.
