Your gesture, next to a star's

1. 1Film or upload one or several gesturesUp to 20 s — strokes, shots, throws: I pick the best one. From your phone's camera or your library. No set-up, no markers.
2. 2I recognise it on my ownForehand, backhand, free kick, free throw: I read the movement and know what you did. You never have to tell me.
3. 3Your skeleton over a star's, in 3DI lay your body over the star's closest to your style, frame by frame, from preparation to finish.
4. 4Up to 3 differences, explainedI show the main gaps — never more than three — in the order they matter, on the video, and tell you what to feel.
5. 5Retry, I checkYou do it again and I compare: what improved, what is left. One thing at a time.

Tennis (forehand, backhand, serve) · Football (free kick) · Basketball (free throw) — I recognise the gesture on my own. More sports are coming.
