Build real speed with a coach in your pocket. Speed Mastery by Sprint University creates a complete training plan for athletes who want to accelerate faster, reach higher top speeds, and perform when it matters most. Built with professional sprinter and Sprint University founder Lawrence “L.O.” Johnson, Speed Mastery organizes your track work, strength training, recovery, and competition schedule into one adaptive program based on proven sprint training principles. A COMPLETE SPEED DEVELOPMENT PLAN Tell Speed Mastery your event, training days, meet schedule, equipment, and goals. The app builds your season through the right phases, from general preparation and acceleration development to max velocity, speed endurance, and tapering. Miss a workout, change your schedule, or add a competition? Your plan adjusts. TRAIN THE RIGHT QUALITY AT THE RIGHT TIME Your program balances the key components of speed development: • Acceleration • Maximum velocity • Speed endurance • Sprint mechanics • Plyometrics • Strength and power • Mobility and recovery Every session has a purpose, so you always understand what you are training and why. READINESS-DRIVEN TRAINING Speed Mastery reads HRV, resting heart rate, and sleep data from Apple Health, then combines it with a quick daily check-in and CNS tap test. When you are ready, the app helps you push. When fatigue is elevated, it can reduce volume, lower intensity, or substitute recovery work before poor training turns into a setback. STRENGTH TRAINING BUILT FOR SPEED Develop the force and power needed to sprint faster with structured strength phases, including: • Eccentric, isometric, and concentric training • Overcoming isometrics • Eccentric overload • French Contrast • Olympic lift variations • Sprint-specific plyometrics Each method includes clear instructions, coaching cues, and setup guidance. AN AI SPEED COACH THAT ADAPTS Make changes using plain language: “Make Wednesday lighter.” “I race on Saturday.” “Add more acceleration work.” “Give me a lower-body isometric session.” Your coach updates the plan for your review while considering your schedule, equipment, training history, and physical limitations. BUILT FOR SPEED Speed Mastery is designed for: • 60m, 100m, 200m, and 400m sprinters • Football, soccer, rugby, and field-sport athletes • Jumpers and explosive athletes • Coaches building structured speed programs • Any athlete serious about becoming faster TRACK EVERY SESSION Log sprint times, exercises, sets, reps, weights, and readiness. Use target weights based on your 1RMs, built-in plate math, rest timers, Live Activities, and a season calendar that shows how every workout fits into the bigger plan. Stop guessing. Start training for speed. Master your acceleration. Raise your top speed. Perform when it counts. Speed Mastery by Sprint University.
