Yoga stretches and tightens the abdomen

Use your left hand to reach the right crotch from behind and try to reach the base of the thigh. If you can't, you can also touch the crotch. Turn your right hand to the left, try to touch it backwards on your waist. Turn left until you can't move. When you can see the rear, stay for a few seconds; then change to the other side and do the same. Do one set after both sides, and do five sets at a time. Every time you get up to drink water or go to the bathroom, do it and you will feel the muscles in your lower abdomen tightening.

If you don't want to move so much in the office, you can just turn your shoulders, put your shoulders flat, straighten your waist, try to turn your shoulders and waist left and right, and turn your shoulders about 90 degrees. You can also have the same effect. (Editor in charge: Chen Shaopeng)
