Basketball, shooting
Jump slightly backwards as you shoot, keeping your shoulders square to the rim.
Beta: we're less sure how well one camera can judge this move, so treat the scores as a rough guide.
Phone at hip height, about 3 metres away, filming you from the side. Keep the ball in the picture too.
Your whole body, head to feet, needs to be in the picture. The coach will remind you if it can't see you.
Bend your knees
You shot with straight legs. Dip your knees and push up, because the power comes from your legs.
Straighten your arm
Your shooting arm didn't straighten. Reach up and finish with a straight elbow.
Release higher
The release was low. Shoot up and out, high above your forehead.
Hold the follow-through
You dropped your hand straight away. Hold your wrist up, fingers pointing at the rim, for a second.
More arc
The ball came off flat. Push it up higher so it drops down into the hoop.
