Abdominal reduction every day 1 hour, not necessarily every time 1 hour, can be done several times, but not less than 5 minutes each time, not less than 1 hour every day. If you can persist for a month, the effect will be remarkable. This is the simplest and most effective way to reduce abdomen I have ever seen. When you tuck in your abdomen, you must tuck in your abdomen, hold your head up and chest out, and put your hands behind your back. I wish you success! The sooner the waist, the better. In fact, the figure of a boy is also very important.
