Raise your hand to the right and wave it over your head. Your left leg moves to the highest point like a rubber band jump, and then continue to practice in the opposite direction, which can exercise the strength of the waist, increase the flexibility of the waist and relax the waist. When the body rotates, the arms should be lifted first, then rotated to the left, then lifted, and then rotated to the right. During the movement, the legs should be spread out, shoulder width apart, and then the movement should be carried out.
