MISTAKE: An Unnatural Posture
Improper form is usually a result of runners trying to assume an unnatural posture. Most people run upright—head over shoulders and hips—and yet they decide to lean forward because a friend says it helps, says Galloway. An unnatural lean can cause back, neck, and hip pain.
FIX: Go Natural
Ditch the fads, and run in a way that’s natural for you. Look ahead, keeping your upper body relaxed and upright. Maintain a short stride length; land mid-foot and work towards a quicker cadence. With those pieces in place, your body will automatically settle into its gait and you’ll find that natural rhythm your body craves.
