Clockwise rotation follows the 12-3-6-9 pattern.
Imagine that the axis of the rotation extends from your navel through the center of the device.
Then move your pelvis and hips in a circular direction around that center of rotation.
Repeat 5-10 times.
Counterclockwise rotation follows the 12-9-6-3 pattern.
