Key takeaways
- 1The diaphragm is the primary breathing muscle — a dome under the lungs.
- 2When it contracts, it descends. Air comes in. The belly rises.
- 3Chest-dominant breathing recruits neck and shoulders that should be quiet at rest.
- 4Every paced Auralize pattern trains diaphragmatic breathing implicitly.
The mechanics, briefly
The diaphragm attaches to the lower ribs and lumbar spine. Contraction pulls the dome downward, expanding the thoracic cavity and drawing air in. The abdominal contents move outward because the diaphragm displaced them. That is why the belly rises.
Accessory muscles — scalenes, sternocleidomastoids, upper trapezius — help during heavy breathing. At rest they should be quiet. If you feel your shoulders lift on a normal inhale, you are recruiting them unnecessarily.
How to check yours
Sit or lie down. One hand on chest, one on belly. Breathe normally. Which hand moves first? Which moves further? Diaphragmatic breathing has belly moving first and further, chest moving second and less. If it is reversed, you have a chest-dominant pattern.
How to train it
Any paced Auralize pattern where you keep the shoulders down and let the belly move first is diaphragmatic breathing practice. Coherence at 5.5-5.5 is a gentle default. There is no separate "diaphragmatic breathing pattern" you need — there is only the movement pattern applied to any rhythm.
