1 chest breathing-Breathe with the upper and middle parts of the lungs, and feel that the chest is expanding and contracting, and the abdomen is relatively motionless.
Practice: sit cross-legged, keep your back straight, put your hands on your ribs, inhale slowly through your nostrils, feel your ribs expand outward, lift your hands upward, and feel your ribs move downward and move inward.
Abdominal breathing-breathing at the bottom of the lungs, only feeling the abdomen stirring and the chest relatively static.
Practice: lie on your back, put your hands on your abdomen, inhale slowly through your nostrils, relax your abdomen, and feel the air being sucked into your abdomen. Your hands can feel your abdomen being lifted higher and higher. In fact, at this time, the diaphragm drops, pressing the air to the bottom of your lungs. When exhaling, the abdominal muscles are slowly contracted, the diaphragm rises, and the air in the lungs is discharged.
Complete breathing-the upper, middle and lower parts of the lung are involved in breathing. Abdomen, chest and even the whole body have a feeling of ups and downs. Only this kind of breathing is the ultimate breathing requirement of yoga.
Practice: sit cross-legged, with one hand on the abdomen and the other hand on the ribs, slowly inhale, feel the abdomen bulge slowly, and let the air fill the lower half of the lung first, and then the upper half of the lung. Now the air fills every corner of the lungs. You have inhaled the maximum capacity of both lungs, then exhale slowly, first relax the upper chest, then relax the chest and abdomen, and finally contract the abdominal muscles to breathe out the air completely.
