I'll tell you the simplest and most effective method. I have personally experienced that my appearance in about three months has been reduced from 73 cm to 64 cm now, which is a waist circumference of 1.9 feet.

Before going to bed every night, lie in bed, make fists with your hands and pat your waist, not your back. It is the position where the arm is put down vertically, which is the thinnest part of the body. Tap 200 times at the same time, then put your hands on your abdomen, rub it slowly clockwise for 20 times, then slowly counterclockwise for 20 times, alternating left and right for 5 times, that is, 200 times, lasting for half a month.
