The specific method is as follows:

1, hold each other with palms crossed, and stretch upward until you feel the tension stop and stand still.

2. Hold the elbow of the other hand with one hand and slowly pull it inward toward the head.

Put your hands behind your back, grab each other, and then slowly raise your arms to a comfortable position and keep this posture.

4. Feet are shoulder width apart, knees are slightly bent, one hand extends out over the top of the head, the other hand is naturally placed in front of the abdomen, and the waist is bent outward.

5. Straighten your palms outward, spread your arms outward, and then slowly pull back until you feel the muscle tension in your chest, shoulders and arms.
