What it is
Sway measures lateral (side-to-side) motion in your form. A lower sway score suggests that your form has excessive lateral motion while a higher sway score suggests that your motion is in alignment with the direction that you are running.
Why it matters
- Excessive sway wastes energy that should propel you forward
- Can lead to IT band syndrome and hip pain
- Reduces running efficiency and increases fatigue
- Often indicates weak hip stabilizers or core muscles
