Abdominal breathing is the most basic breathing method. It is the basis of learning other breathing methods, which can be accomplished by increasing the activity of diaphragm and reducing the movement of chest.

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.

Abdominal breathing skills:

Abdominal breathing can be divided into forward breathing and reverse breathing. Forward-leaning breathing refers to gently expanding abdominal muscles when inhaling, inhaling as deeply as possible under the premise of feeling comfortable, and contracting muscles when exhaling. Reverse breathing is the opposite of forward breathing, that is, gently contract the abdominal muscles when inhaling and then relax when exhaling.

In this way, breathing will become slow, occupying only about half of the vital capacity. Gently press the tip of the tongue to the upper jaw. The subtle difference between reverse breathing and forward breathing: breathing only involves the muscles of the lower abdomen, that is, the pubic region directly below the navel. Gently contract the muscles in this area when inhaling, and relax when exhaling.
