Bending down and touching shoulders left and right is a yoga practice. This action is to stand on tiptoe, straighten your upper arm, open your fingers to support your upper body, exhale, raise your left hand and gently pat your right shoulder. At this time, your right arm will support your upper body independently, pat your shoulder and then fall back to its original position, then lift your right arm and pat your left shoulder. This action can exercise the abdominal muscles, increase the stability of the shoulder joint, and make the big belly thin into a small waist.
