Breathing is breathing. Breathing is a normal physiological phenomenon of human beings and an important way to maintain health. The breath of human beings carries the energy of life. General breathing mainly includes chest breathing (natural breathing). Chest breathing mainly focuses on the activities of ribs and sternum, and the breast diameter increases before and after inhalation. Because when breathing, air directly enters the lungs, so the chest will expand and the abdomen will remain flat.

Abdominal breathing is often used in practicing internal boxing, which can be divided into anterior abdominal breathing and posterior abdominal breathing. Abdominal breathing means moving the diaphragm up and down. Because when inhaling, the diaphragm will drop and squeeze the organs below, so the stomach will expand, not the chest. Therefore, when exhaling, the diaphragm will rise higher than usual, so you can take a deep breath and spit out more carbon dioxide that is easy to stay at the bottom of the lung.

The basic point of reverse abdominal breathing is to inhale through the nose and breathe through the mouth. When inhaling through the nose, the chest rises and expands outward, then the abdomen retracts, and the feeling of inhaling "qi" reaches the lower abdomen (Dantian). At the same time, the tongue touches the palate and the mind is placed at the door of life. On the contrary, when exhaling, the chest descends and contracts, the abdomen expands outward, and the tongue is flat. Pay attention to deep, long and even reverse abdominal breathing. "Deep" means that the feeling of inhaling "Qi" is to the lower abdomen (abdomen), which is different from the feeling of inhaling "Qi" only to the chest; Reverse abdominal breathing should not be too full when inhaling and not too full when exhaling, leaving room to avoid holding your breath.
