Fun FACT: Did you know?
The lungs do not actively expand and recoil themselves. Your diaphragm and the elevation and depression of your rib cage act upon the lungs in order to create the movement of air. Not only that, when you breathing heavy here at ADAPT the action of your diaphragm and chest cavity alone is not enough, you must contract your abdominals to provide the necessary respiratory response.
So, when you are here at ADAPT do not forget to take deep breaths and squeeze your abs!
