Cricket, batting
Back foot across to a short, wide ball, and slap it square with a horizontal bat.
Beta: we're less sure how well one camera can judge this move, so treat the scores as a rough guide.
Phone side-on to you, where point would stand, about 4 metres away at hip height. Shadow bat: no ball needed.
Your whole body, head to feet, needs to be in the picture. The coach will remind you if it can't see you.
Roll your wrists
The bat finished high, which lifts the ball in the air. Roll your wrists over to keep it down.
