Basketball, defence
Wide base, hips low and back, arms out to seal off a rebounder.
Best on camera: a slow, steady move with your joints in clear view.
Phone at hip height, about 3 metres away, filming you from the side.
Your whole body, head to feet, needs to be in the picture. The coach will remind you if it can't see you.
Sit lower
You weren't low enough. Sit into a wide, low base to hold your spot.
Chest up
You bent over. Keep your chest up so you can see the ball.
