We increase lung capacity up to 33% by releasing microfibers (mild scar tissue) and tension that are restricting chest expansion. As the chest becomes more flexible, more air can be moved in and out of the lungs.
Chest expansion (and lung capacity) can be restricted by lifting weights, lung infections (allergies, colds, bronchitis, pneumonia), sports impacts, auto accidents, poor posture, chronic breath holding and chest surgery.
As the chest expands, the voice deepens, becomes more resonant and there is more air available to effortlessly project the voice.
We encourage all speakers to order our directions for measuring their chest expansion as conventional vocal coaches will not do this. http://www.somaxsports.com/breathing.php
