Lie on your back with your knees bent and your feet flat on the floor.
Flatten the small of your back against the floor and tighten your abdominal muscles.
Lift up your arms so they are pointing to the ceiling.
Tuck in your chin.
Reach one arm forwards at a time, lifting each side of your body with the movement.
To lower back down, bring one shoulder back at a time, keeping your arms straight as you lie back.
