Setup

You need a flat, non-slip straight of about 20 meters. Jog easy for 5 minutes first, because this drill strikes the ground hard and cold hamstrings strain easily. Then start running at a moderate pace.

Execution

While running, actively bend the knee and pull the heel up toward the glutes on every step.
As the hip extends, snap the foot down fast and hard, landing right under the hip.
Imagine the foot "clawing" the ground backward the instant it touches down.
Keep your torso upright, arms swinging naturally opposite the legs.
Maintain this technique for the whole distance, then walk back to rest.
One set is 2-3 runs of 20 meters, about 20-30 seconds of drill running, walking back between them; once the foot strike loses its snap, stop.
A sharp or unusual pull in the back of the thigh ends the drill for that session; do not try to finish the run.

Breathing

Breathe evenly with your running rhythm, without holding your breath.

Quick cues

Pull the heel toward the glutes.
Claw the ground right on contact.
Land right under the hip.
Torso stays upright.

Common faults

Fix: Shorten the stride and focus on landing right under the hip.
Fault: Not pulling the heel high enough toward the glutes
Fix: Slow down and exaggerate the heel pull before speeding back up.
Fault: The torso leaning back while running
Fix: Keep the chest tipped slightly forward and the eyes looking ahead.
