Good Form Running
Step 4: Lean
Rather than over-striding or reaching with the feet, Good Form Running utilizes a forward lean to propel the body forward. When you lean, gravity causes your body to fall and your foot instinctively steps in the direction of your movement. By reacting to gravity rather than pushing off from the toes, there is less muscle strain in the legs and more automatic forward momentum.
How to Find it
Stand up straight.
Slowly lean forward at the ankles, keeping the waist still.
At a certain angle your foot will react by stepping forward — this is the most efficient lean for good form.
