Breath Running Foundation - this is a very low effort run, with the goal of breathing deeply and intentionally while keeping your heart rate low. Set pace by ensuring you can inhale (preferably through your nose) for 4 steps, and exhale (preferably through your nose) for 5 steps. Shorten your stride and/or relax your pace to stay in this breathing pattern throughout. Try to maintain a cadence of 160 SPM (Steps Per Minute) or better.
