Important: Before you go any further, to get the most benefit from this book you should ensure you try the following self-test exercise first.
It will act as a reference point for you to measure your progress, and you will be asked to repeat it twice more through the book.
Self-test 1
Take a deep breath, and think about where you can feel the air inside your body. Draw on the picture of the torso below where you feel the air going in your body.
Once you have drawn the full extent of where you feel the air go into your chest, I would like you to note down how you would rate the quality of this breath on a scale of 1 to 10.
Note down your score so you can compare this with the two further self-tests you will do later in the book.
