Treadmill
Start with the belt stopped. Hands rest on the rails only to step on and off.

- 1Begin walking, then raise the speed. Don't jump onto a moving belt.
- 2Land under the hips, midfoot, with a slight lean from the ankles.
- 3Once moving, let the arms swing. Hold the rails only if you need to steady yourself.
Easy to miss: Hanging on the rails, or reaching the foot out so the heel lands well in front of the knee.
