ATHLETIC HITTING DEVELOPMENT / VISION LAB
DON'T COPY A SWING.
UNDERSTAND GREAT HITTING.
The AHD coach-curated reference room. Explore athletic positioning, the bump, MAAs, launch, bat path and adjustability. Compare clips through all seven AHD checkpoints.
AHD Gold Standard means coach-selected examples for education. It does not establish a universally perfect swing or a clinical biomechanical measurement. No professional broadcast clips or uploaded athlete videos are included. Locally selected videos remain on your device and are never uploaded by this page.
01 / THE REFERENCE ROOM
Hitters who show the way.
Eight professional AHD models, plus two approved owner-submitted swings. The first reference's instructional reel is the same underlying swing—not a third reference.
COACH NOTES
What to observe
03 / MOVEMENT SEQUENCE
Seven AHD checkpoints.
All models use the same checkpoints; effective mechanics may have individual differences.
04 / DIGITAL TWIN FOUNDATION
Gold Standard Compare.
Real local video playback, slow motion, frame stepping and coach-tagged evidence. Camera view and timing should be comparable. No automatic analysis or 3D claims.

05 / COACH EVIDENCE
Mark the real frames.
Annotations stay in this browser until you export them.
Evidence timeline
Private cloud video vault and automatic Digital Twin scoring remain staged; they are not activated on the production site. Professional footage must be properly licensed. Minors require verified guardian authorization before future cloud uploads.
06 / FROM VIDEO EVIDENCE TO TRAINING
Build the next seven days.
Compare both videos, pause at the relevant frames, and manually identify a movement priority. We will connect that observation to an existing AHD lesson and a practical seven-day training draft. It does not claim automated 3D analysis.
Record a coach observation
Both videos must be loaded before you can capture evidence.
Ranked priorities
Add the most important priority first. Up to four, with video timestamps recorded for the reference and the athlete.
Training access: Lesson links open existing AHD pages and honor normal course access rules. Exported notes are local coach drafts, not cloud athlete assignments or automatic diagnosis. For a permanent athlete assignment, an authorized coach must publish through the existing private review process.
