Stand up straight, hold your hands close to your head and tighten your shoulder blades at the same time. Hold 10 second, relax and repeat for 5 ~ 10 times. Then, return to the standing position, buckle your hands behind your head, contract your shoulder blades, hold 10 seconds, relax, and repeat 5- 10 times.

Nodding action

Stay seated, with your head slightly tilted, as if nodding. The strength of nodding should be that the neck feels stretched, pause for 10 second, then relax and repeat for 5- 10 times.

Chest lifting exercise

Sit in a chair with your arms at your sides and your feet flat. Slowly raise your chest toward the ceiling, but don't raise your head and keep your chin parallel to the ground. Hold 10 second, then relax and repeat 5- 10 times. Shrink the scapula and return to the preparation posture for the last movement. This time, put your hands on your hips, contract your shoulder blades, and make your chest feel tight. After holding 10 seconds, slowly relax and repeat 5- 10 times. Move your chin forward, keeping it parallel to the ground, then extend your chin, head and neck forward, but don't lean down. Hold 10 second, relax and repeat 5- 10 times. Need to be reminded that when doing this action, you should put your finger on your lips so as to correct the angle and position of your head at any time.
