If you're 5'2 you need to be realistic about your ability. Don't go into the post and try and avoid layups, unless there's a fairly open lane because at 5'2 you will just get blocked. I'd advise working mainly on passing and mid-range jumpers, you can also try to work on 3 pointers, but never rely on 3 pointers. Also, work on defence. If you become good at these things you can still be an asset to the team.
