That isn't exactly what I meant. You actually describe here what I meant. Natural, full breathing. Like when we yawn, or breathe deep for the doctor. The belly naturally expands during that process and allows the lungs to fill to capacity. From there you have at least two or three ways to control the air expenditure. I mean to emphasize that the entire torso is involved in the production and control of the air. n edit: I mean to contrast this type of breathing with "gulping" air.
