Sit upright on a firm surface or chair with your feet hip width apart.
Sit close to the edge so that only your buttocks are on the surface.
Tie a resistance band at chest height to one side.
Hold the other end of the exercise band in both hands and hold your arms outstretched in front of you.
Slowly rotate your body away from the exercise band, keeping your head, shoulders and arms in alignment.
Hold this position before returning back to the centre.
