Cricket, bowling
Seam angled towards first slip, your arm coming over close to your head.
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 your delivery stride, about 5 metres away, so it sees you from gather to follow-through. Shadow bowl: no ball needed.
Your head, arms and hips need to be in the picture. The coach will remind you if it can't see you.
Keep your arm straight
Your bowling arm bent and straightened. Keep it straight through the delivery so your action is legal.
High arm
Your arm came round low. Bowl with a high arm, brushing past your ear.
Follow through
You stopped after releasing. Let your body follow through, bowling arm sweeping across.
