First, shoulder + thoracic vertebrae + cervical vertebra
The hands are grasped at the back, and the arms are stretched straight back, so that the chest shoulders caused by the work at the desk are fully relieved and expanded. The neck and head are tilted back to the limit angle as much as possible, and the breathing is slowly and evenly.
Second, the shoulder and neck triangle
Keep the spine neutral position, sit up straight, lift your right hand up and stretch your elbows, pull your left ear, and extend the neck to the right, keeping your left arm naturally sag. Practice alternating left and right.
Third, exercise fingers
The hand that often knocks on the computer to catch the mouse is stiff and stiff, basically not far from the disability... For the relaxation of the finger, the minimalist method is to first force the fist, and then stretch the palm and fingers as much as possible with maximum force. Repeatedly; or the vertical desktop of the palm, press the four fingers down on the table, which is also the blood circulation of the opponent.
