Hello, first of all before the round you need to hit some shots only using your wrist, just to get them warmed up. Then you do your half shots, three quarter shots, then the full shot. After everything is warmed up, it should be a natural process, as your doing the take away the wrist is not doing to much, but when the club starts to go up it starts to cock until it finally reaches the end of your back swing and thats when it is fully ready to compress the ball on the down swing. Let it happen naturally, only way to play golf. I use to watch Leadbetters videos, just don't like the way he does the shoulder tilts, if you watch the pros they keep their shoulders relatively level.
