Andie Cozzarelli (2:38 marathoner, running coach, and Athletes for Yoga Pro) explains how to use your diaphragmatic breathing to optimize your running. Use this practice to put diaphragmatic breathing in context of your running by strengthening your ability to breathe well through run-specific, dynamic movement, and to improve fluidity through your hips.

Focus: breathing, post-run or workout, anytime your hips or pelvis feel tight
Key muscles: core, hips, diaphragm, pelvic floor
When: pre-workout
