(1) Abdominal breathing: Lie on your back with your hands gently on your navel; When inhaling, suck the air straight to the abdomen; Inhale correctly and raise your hand with your abdomen; The deeper you inhale, the higher your abdomen rises. As the abdomen expands, the diaphragm descends. Then exhale, and the abdomen faces the spine inward; Shrink the abdomen as much as possible and exhale all the exhaust gas from the lungs. When you do this, the diaphragm will naturally rise.

(2) Chest breathing: Lie on your back or straighten your back and take a deep breath, but don't let your abdomen expand; Air is sucked directly into the chest area instead of expanding the abdomen. In chest breathing, the chest area is enlarged and the abdomen should be kept flat. Then, when inhaling deeply, the abdomen faces the spine inward; When inhaling, the ribs expand outward and upward, and when exhaling, the ribs contract downward and inward.

(3) Complete breathing: Complete breathing is the most correct yoga breathing method. You can choose to lie on your back and take a deep breath. First, fill the bottom of the lung, then the abdomen will expand, then fill the middle of the lung, and then the upper half. On the contrary, when exhaling, the upper part of the lung should be sent first, then the middle and lower parts, and finally the abdomen will be squeezed in. This long breathing is a natural breathing method. With a little practice, this complete breathing of yoga has many advantages: because of the increase of oxygen supply, the blood is purified; Strong lung tissue, enhance disease resistance; The vitality and endurance of the chest and abdomen have increased, and the mind has become more sober.
