Challenge…perform the running portions of this workout using only nasal breathing. Inhale and exhale through your nose, and if you find that you’re unable to do so, slow things down until you can regain your nasal breathing pattern. When you get into the gym for the burpees and pull-ups, breathe however enables you to move through quickly, but once you start running again, work to resume nasal breathing as quickly as possible.
