Part of running form is a natural response to your speed! Some examples are: ✅ Arm swing ✅ Heel rise and knee lift If you run slow and easy, efficient form will have: 👉 Little to medium arm movement 👉 Low heel rise at the back and low knee lift in front If you run faster, your feet will hit the ground with more force, giving a greater natural return of energy. At faster speeds your form will naturally have: 👉 Higher arm swings at the front and behind 👉 Higher heel rise and a higher knee lift
