Unlock the mechanics of speed by training the wiring — not just the muscles.
The Earthen CoreFire Sprint Drills guide is a simple, powerful introduction to sprint mechanics designed to teach your body how to move fast, efficiently, and with clean neural output. Inside, you’ll learn the three foundational drills every sprinter needs, along with progressions that build posture, rhythm, coordination, and elastic strength safely and naturally.
Whether you're new to sprinting or rebuilding your foundations, this guide gives you the exact tools to develop speed the way the nervous system prefers.
✔ Three essential sprint drills: A-Skips, Wall Drills, Straight-Leg Bounds
✔ Step-by-step instructions for perfect execution
✔ Progressions so you can build safely as your mechanics improve
✔ A simple weekly training framework
✔ Earthen CoreFire cover design for a premium feel
✔ A clear, professional health disclaimer
This is the same foundational approach used by elite sprinters — simplified for beginners so you can start immediately.
Speed begins in the nervous system, not in the muscles.
These drills train:
timing
rhythm
posture
foot strike
motor unit recruitment
elastic energy return
When the wiring is clean, the body moves faster with less effort.
This guide helps you build that wiring.
Beginners learning how to sprint
Adults returning to athletic movement
Anyone who wants better coordination and power
Athletes rebuilding after injury or long breaks
Coaches who want simple, effective mechanics drills
