Negative Step Sprinting: Physics, Biomechanics, and Training for Elite Acceleration

Learn the physics, biomechanics, and coaching principles behind negative steps and negative foot speed in elite sprinting. Includes research, drills, visuals, and training methods.
Physics of Sprinting: Forces, Posture, and the Foot–Ankle Advantage

A coach-tested, research-backed guide to the physics of sprinting—forces, posture, foot–ankle stiffness, and drills for start, acceleration, MaxV, and speed.
The Standard Model of Sprinting: Why Modern Biomechanics Has Changed the Game

Discover how modern biomechanics is reshaping sprint training, replacing outdated “base building” with max velocity and acceleration-first methods.
MaxV is King

Discover why maximum velocity (MaxV) is the king of sprint training. Learn how improving MaxV boosts acceleration, speed, and neuromuscular performance.
Sprint Qualities

Sprint qualities explained: power, RFD, stiffness, elasticity, posture, and speed endurance. Practical training, tests, and progressions to get faster now.
Sprinting Simplified

Sprinting Simplified is a beginner’s guide to running at true top speed. Learn the phases of a sprint, the mechanics that drive speed—force orientation, stride, thigh angular velocity, and leg stiffness—and how to build posture, arm action, and foot strike to get faster safely while avoiding common injuries.
