I once tried a method, and the effect is still good. I will share it with you, that is, stand with your back against the wall, stick all parts of your back against the wall as much as possible, hold your head up and hold your chest high, and your hands in the air must stick to the wall. Think of yourself as a dog skin plaster, and your movements must be in place. You can't cut corners and stand for half an hour after dinner. Don't underestimate it. As long as the action is in place, you may even get five points at first. I lost weight from 60kg to 46kg. I don't remember a few months, but it wasn't long. . And sit-ups before bed. The method is to sit in a group of 15, divided into three groups, and each group is separated by five minutes. This was taught by my sister-in-law's physical teacher, who said it was a healthy practice. If you are too aggressive, you will grow muscles. I hope it helps you.
