Learning how to breathe during a run is crucial. If you don't practice, you will find yourself struggling to get oxygen into the lungs. Aim to take three footsteps for each inhale and two footsteps for each exhale. This 3:2 pattern will give you a lower heart rate on runs and help you get more oxygen into the body.
Practice this technique for the next two weeks and see what happens. You will be amazed by the difference in your breathing patterns. This is a beneficial habit to build for anyone who wants to be a healthy runner. The easier it is to breathe, the easier it is to keep going!
