Lie on your back with your knees bent with your feet flat on the floor and your head supported on a pillow.
Cross your arms over your chest and gently contract your core muscles.
Using your upper torso, turn to one side and then the other while keeping your head supported on the pillow but allow your head and arms to follow the movement.
Keep your shoulders and neck muscles relaxed.
Continue to turn from one side to the other, ensuring to keep your core muscles activated
