Proper breathing mechanics are essential for optimal function, good posture and core stability. During ideal breathing, the diaphragm descends symmetrically on inhalation; the lower rib cage moves proportionately to the front, back and sides; and the abdominal wall expands. At the end of each inhale, the breastbone moves forward and ribs expand. These internal movements allow the belly to expand on the inhale and contract on the exhale.

Breathing practices, around since ancient times, have recently grabbed international attention and popularity among health and fitness enthusiasts to improve health and boost athletic performance.
