““Midline stabilization is always the first thing to go when you set off on a run. For that reason, you must be careful to remember each step in the posture checklist. Make sure your midline is stable, maintain a neutral head posture, and keep your arms bent at 90 degrees with your shoulders externally rotated. Even if your mechanics are not up to par, simply maintaining the integrity of your posture will help reduce the onset of fatigue and keep injuries at bay.””
