Rhythmic Breathing is the best way to control your breathing while running. It helps your pace as well as enhances your overall running experience. First, you want to make sure you are inhaling deeply
To get rhythmic breathing down, you have to inhale for three steps. This allows time for your body to receive the oxygen it needs.
After inhalation, you want to exhale for 2 steps. Make sure it is a controlled and deep exhalation.
Continue the process of inhaling for 3 steps, exhaling for 2 steps. Repetition will guarantee solid airflow.
