[step] Breathe in through the nose, concentrating on filling your lungs with air the way you would fill a glass with water. Expand your chest and concentrate on slowly filling every available space.

Ending1: Inhale through your nose for 2-3 breaths. [substeps] Inhale for 4-5 breaths in a series of four on a four-count cycle. Ending2: To get a better sense of how much room you need, you can try lightly changing the position of your stomach-if you're worried about it expanding, stop breathing again. [substeps] Making your inhales slow and deep will be easier on your body. Ending3: [substeps] When you inhale, the air in your lungs pushes the diaphragm down, which naturally causes your abdomen to protrude. However, too often people learn as adults to suck in their abdomen, which means you're not taking in as much air as you should. Ending4: [substeps] Slowly move your torso and head from your forehead to your chest. Press your belly button inward to bring and release more blood to your belly area.
