Breathing in physical exercise has three major functions: gas exchange, maintaining trunk stability and maintaining intra-abdominal pressure.

Breathing provides the human body with oxygen needed for exercise and discharges carbon dioxide.

Correct way of breathing: Breathing can be divided into chest breathing and abdominal breathing.

Compared with chest breathing, abdominal breathing inhales more air and makes the body more stable.

Therefore, when exercising, try to recommend abdominal breathing.

Take running as an example, take a deep breath slowly: breathe in through your nose, exhale through your mouth, and keep the rhythm. It's like three steps and one breath, three steps and one breath, inhaling through the nose and exhaling through the mouth.
