Inhale through the nose. When inhaling through the nose, the nasal cavity can preheat, warm and moisten the inhaled air, and the mucus and nose hair in the nasal cavity can also block the dust and bacteria in the air. Breathing through the nose can meet the human body's demand for oxygen intake and carbon dioxide discharge. Moreover, only breathing through the nose can exercise the respiratory muscles, thereby increasing vital capacity and enhancing oxygen supply capacity.

Abdominal breathing. Abdominal breathing can make the diaphragm contract and move down to a greater extent, and the lungs expand to the maximum, naturally inhaling more oxygen.

Grasp the breathing rhythm. Choose two steps and one breath, two steps and one breath, or three steps and one breath when running. Whether it is two steps and one breath or three steps and one breath, exhalation basically corresponds to landing on the same foot, which has great impact pressure on one side of the body.

When running, you can try the rhythmic breathing method of three steps and one breath and two steps and one shout. When you exhale, your feet land alternately.
