how to breathe with your belly

Diaphragmatic breathing, or deep breathing is breathing that is done by contracting the diaphragm, a muscle located horizontally between the thoracic cavity and abdominal cavity.

Air enters the lungs and the chest rises and the belly expands during this type of breathing. Diaphragmatic breathing is also known scientifically as eupnea, which is a natural and relaxed form of breathing in all mammals. Eupnea occurs in mammals whenever they are in a state of relaxation, i.e. when there is no clear and present danger in their environment.
