2, more exercise, running is essential, with sit-ups, push-ups, etc. Personally recommend a way, put your hands on the ground or beside the bed, turn your body clockwise 10, then counterclockwise 10, and do it every day when you are free. In the process of turning, you will reach the maximum! After three days, you can feel your stomach pulling back.

3, usually keep the abdomen and lift the gas. At first, you may not like it a little. After a while, it will become a natural state. Another advantage is that the temperament of the whole person has improved!

4. If you can't sit, don't sit. If you can stand, stand!
