Remember to read the notes on abdominal techniques for extra guidelines.
Place your feet in tight towards your bottom, or rest them on a bench, to isolate your abdominals.
With your hands locked behind your head, keeping your chin off your chest, come up to an angle no more than 30 degrees.
You should commence the exercise with your shoulders and aim to keep the elbows out by your sides.
Stop immediately if you feel any pain.
