Begin by laying down on a mat, towel or similar, your feet should be flat on the floor with your knees bent to 90 degrees
Place your fingers on your temples either side of your head with palms facing forward
Whilst contracting your stomach muscles, slowly raise your shoulders towards your knees until you can go no further
Now slowly lower your body back down to the floor
Repeat steps 3 and 4 until you can no longer maintain correct technique
To protect your neck, you should always lead with your shoulders and not your neck
Be sure to contract your stomach muscles throughout this exercise
This exercise should always be performed slowly so you use your muscles rather than momentum to move
