Lie on your back with your legs elevated on a chair or bed.
Your hips should be at 90 degrees, as should your knees.
Ensure your head is well supported so that you can relax in this position.
Place your hands on your abdomen, either side of your belly button.
The focus of this exercise is your breathing and diaphragmatic movement.
Breathe in.
Imagine the air filling down to the bases of your lungs and round to the back of your rib cage.
As you steadily inhale, you should feel your belly rise into your hands.
Breathe out.
Imagine the air being pushed from the base and back of your lungs as it moves further up and finally out of your mouth.
As you exhale you should feel your belly relax down again.
Continue this movement, focusing on your belly rising up as you inhale, and relaxing back down as you exhale.
Do not allow the bottom of your ribs or your back to push upwards as you inhale.
