Attach a resistance band at just below shoulder height (or use a cable machine with the cable originating at this same level) stand with your feet slightly wider than hip width a part and hold the end of the resistance band or cable with your arms out straight and your eyes looking at your hands as shown.
Activate your core but drawing your bellybutton in towards your spine, squeeze your buttocks and rotate your body away from where the resistance band (or cable) originates breathing in as you do so.
Breathe out and control the movement back to the starting position. This completes one repetition.
Place your tongue on the roof of your mouth to support your neck through this exercise. Keep your arms straight throughout and your core active to support your lower back.
