Ground Contact & Triple Extension Logic

Ground Contact & Triple Extension Logic

A-Skips and Ankling directly train the stiffness-to-compliance ratio your ankle and Achilles need for explosive toe-off, while Build-Up Strides prime the neuromuscular recruitment pattern that carries into max-effort Acceleration Sprints. Every drill here isolates a mechanical variable — posture, ground contact time, or limb cycling — before combining them at speed.

The First 10 Meters Are Everything

The First 10 Meters Are Everything

Acceleration is a distinct biomotor skill from top-end speed, demanding near-horizontal force application and powerful hip extension rather than upright mechanics. Your central nervous system, fast-twitch Type IIx fibers, and ATP-PCr energy system all peak and fatigue within seconds — which is exactly why full recovery between reps isn't optional, it's the adaptation stimulus.

RAMP Protocol Meets Neural Readiness

RAMP Protocol Meets Neural Readiness

The warm-up sequences from Easy Jog through High Knees and Butt Kicks follow the RAMP model — Raise, Activate, Mobilize, Potentiate — progressively increasing tissue temperature and motor unit excitability before your CNS is asked to fire at sprint intensity. To personalize, extend your Build-Up Strides by one rep if your first acceleration feels flat or mechanically disconnected.
