1, press the hand on the right side of the head to push the head to the left, and at the same time, the neck resists hard, not easily overwhelmed, but gradually overwhelmed. Then, the neck forcibly lifts the head to the right, and the right hand forcibly presses the head to prevent the head from being easily lifted, but gradually becomes completely vertical. Repeat this many times until the neck feels sore.

2. After practicing one side, change to the other side. Press the head hard with both hands to make it bend forward and downward. The neck resists hard to prevent it from being pressed down easily, but it gradually presses to the neck and touches the clavicle handle. Then, the neck forcibly lifts the head upward, and at the same time, both hands forcibly press the head to prevent the head from being easily lifted, but gradually lifts it to its original position.
