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