Healthy, full breathing involves significant expansion of the rib cage in all directions. I wish people would remember this before spreading the advice, “breathe into your belly, not into your chest.” Your lungs are in your chest. (And contrary to the article, by the way, the “lower part of your lungs” is not “just above your belly button.”) Most importantly, do not lock your chest or inhibit its movement. If you have poor posture and core support and a tight chest, I would say experiment with filling your lungs completely, and with engaging your abs very slightly on the _inhale_, to feel some of the sensations of full, supported breathing. Your core muscles create pressure that helps fully inflate your lungs. Don’t listen to any admonishments about “breathing wrong” as your body will use them to create additional tension and restriction rather than relaxation and freedom.
