Keeping you head still

[neilcrook]

Recently had a couple of lessons with a local club pro which really helped at the time. He noticed my major flaw almost immediately and spent three lessons trying to correct it. I was lifting my head too early (too try and see how far off my shot was I guess).

Trouble is that outside of the lessons, without the constant reminder to "keep your head still" I start to slip back into my old routine.

Can you suggest a good drill to follow to iron out this annoyance - neck brace, perhaps ...
