Cricket, batting
Feet shoulder-width, knees soft, head still and level, eyes on the bowler.
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.
Feet a bit wider
Your feet were too close. Stand with them about shoulder-width apart.
Feet closer together
Your stance was too wide to move quickly. Bring your feet in to shoulder-width.
Soft knees
Your knees were locked. Keep them soft so you can move forward or back.
