After eating every day, keep standing for at least half an hour, and then you can do some simple stretching exercises, which can not only exercise, but also keep fit. It is especially useful for thin waist and thin legs. After a long time, you will gradually like standing. It feels easier to stand than to sit now. The most important thing is, after a period of persistence, I will feel very tired every time I eat, and I just want to stand and exercise. Will gradually become thinner (for friends with more waist fat, you can try to turn the hula hoop, which is very effective). Remember: don't do exercise for half an hour after dinner. It's not good for your health. Just stand. This is my personal experience. You can try it if you are interested.
