High Twists

Lie on your back, with your feet secured under a step-box or other similar object (sofa).

Having your feet secured will reduce the effectiveness of your abdominal muscles, as the muscles that aid leg lift (Hip Flexors) will greatly aid the movement.

Beginners should use this method if suffering with weak abdominals, in order to help progress through a greater range of exercise's.

With the feet secured, you will find that you can perform more exercise's, such as the high oblique twist.

Regardless of the exercise you perform, always stay within your own limit, working with good technique throughout, stopping immediately if you feel any pain or discomfort.

Aim to progress the number of reps that you can perform, as your abdominal strength increases.
