If you’ve ever done any speedwork, you know just how quickly your breath and heart rate can spike to an uncomfortable level. You’ll even get a chance to practice that uncomfortable feeling in the exercises we’ve got coming up in this article.

Ease that transition by practicing your breathing before you even get on the road or into the workout. Learn how to avoid shallow chest breathing and instead fill your lungs with belly breathing and you’ll bring more air into your body with every breath. More air equals more oxygen getting to your muscles.
