A single video. Real coaching.
Measurable improvement.
Not another “AI personal trainer.” Not a generic drill library. Every step is built on Kevin Fessette's actual coaching methodology.
Film Your 40
Set your phone on the sideline, 5 yards from the 20-yard mark. Record a single sprint from side-view. That's it — no special camera, no multi-angle rigs. Want better data? Film 2-3 reps in one session for confidence scoring.
- ✓Side-view camera angle
- ✓~5 yards from the 20-yard mark
- ✓Full 40-yard dash (includes acceleration + max velocity)
- ✓Multi-rep sessions for consistency scoring
AI Extracts Your Mechanics
Your video uploads to our GPU pipeline. MediaPipe pose estimation tracks 33 skeletal landmarks every frame. We measure 20 biomechanical signals — arm path, hip drive, knee lift, foot strike, stride length, cadence, contact/flight time.
- ✓MediaPipe BlazePose (33 landmarks)
- ✓20-issue sprint mechanics taxonomy
- ✓Stride cycle detection + temporal analysis
- ✓Projected 40-yard dash calculation
Get a Coach's Report
Claude AI generates a coaching narrative written in Kevin's voice — what you're doing well, your top 3 priorities, and exactly why each issue matters. Plus a coach-filmed demo video for every drill we prescribe.
- ✓Written in Kevin's coaching voice
- ✓Top 3 priority issues (cascade order)
- ✓Per-issue drills with demo videos
- ✓PDF export for parents/coaches
Train With Kevin's Drills
Your Training tab shows the exact drill to work on for each issue — 55 drills across 3 severity levels (Red/Yellow/Green). Every drill has Kevin's demo video and exact coaching cue. Mark them done as you go.
- ✓55 drills, 20 issues, 3 severity levels
- ✓Cascade priority: arms first → everything follows
- ✓Demo videos filmed by Kevin
- ✓Completion tracking + streak counter
Re-Analyze and Prove It
After 2-3 weeks of training, film again. The Improvement Summary shows your deltas: P40 time, stride length, cadence, elbow angle, issues resolved. Not 'you kind of look faster' — actual numbers.
- ✓First vs. latest analysis comparison
- ✓Quantitative deltas for every metric
- ✓Issue severity changes (HIGH → YELLOW → Clean)
- ✓Built-in re-analysis nudge at 6+ drill completions
