Can you feel your diaghram expand? This takes lots and lots of practice. It is hard to feel. Don't get discouraged. It will get easier. I want you to keep doing it throughout the day. Try this sitting in a chair, standing up, or lying on the floor. Imagine a balloon expanding in you. Do it at work, on the subway, at home and as often as you can. Just not in speaking situations yet. You are not ready. Tune in tommorrow for more. If your are breathing with your shoulders raised, then this will produce tension. Breathe like you are inhaling through a long tube below your lungs.
