Feet Raised

Lie on your back, with both legs off the floor, bent at 90 degrees, so that your lower leg is parallel to the floor.

Interlock your fingers behind your head, keeping your elbows pointing out to the side. Use your hands to support the weight of your head, not to pull yourself up with, your abdominal muscles should only perform this.

Keep your chin away from your chest throughout the movement, by looking upwards, aim for your spine and head to be aligned.

Exhale and slowly lift your shoulders - elbows - head, as a complete unit, avoiding bringing in your elbows or bending the neck.

On full contraction of the abs, you should aim to have lifted 30 degrees off the floor, holding the position for a split second prior to exhaling and lowering under control ready to perform your next rep.

Beginners, should aim to perform 2 sets of 8 - 10 reps, however if this is difficult or causes any pain in your back, have your feet supported.

Intermediates aim for 12 - 20 reps repeated twice.

Advanced work for 20 - 30 reps repeated three times.

The key focus point for this exercise is the speed you perform the movement. Avoid momentum and bouncing off the floor, keep the action smooth and slow so that you can feel your abs contracting.
