There are some small ways. I hope I can help you.
Don't sit after dinner. This must be observed. Besides, I like to press my waist hard with my hands when I stand. Remember the way to hug. I don't know when I got into this habit, but I accidentally found in a report that this action can actually slim my waist. In the process of pressing, n small fat cells are compressed into large ones. Slowly compressed into a small one. So as to achieve the effect of slimming.
My waist has always been the size of three hands. About 65 centimeters. It's not a snake waist. But at least I'm satisfied. Well, it should be possible to slim down to below 70.
