One big key to a powerful golf swing, is to use the front shoulder to push the arms and club all the way to the top of the backswing. You see many, many tour players these days using a little push from the front shoulder (pre-shot move) that replaces the waggle*. This is preparing the front shoulder to start the swing, not the hands.
Now, one subconscious movement that will stop the shoulder from continuing to push to the top, is to actively start hinging our wrists. Once this starts, the shoulder will stop pushing and the hands will hinge and lift (weak not repeatable). Also, the hands (almost never) hinge the club correctly, so that problem will have to be fixed on the downswing. We want to push with the front shoulder until the club hinges on its own close to the top of the backswing.
If the front shoulder controls the backswing, the club will hinge perfectly, so on the downswing, it can unhinge on its own when it should. Again, keeping the hands passive will allow all this to happen for a more consistent golf swing.
One trigger I use with my students on the backswing is, when the front shoulder touches or arrives under your chin, START THE DOWNSWING**.
* I believe the waggle to be a detrimental movement. It is preparing the hands to take over. In a Large Muscle controlled golf swing, the hands take a passive roll to allow the Large Muscles to do their job. Actively moving the hands prior to the swing, works against what we want to do. Say goodbye to the waggle and use the Front Shoulder pre-shot move. This is the move that will start the swing so let’s practice it just before we start the swing!
** The downswing starts with the hips/thighs unwinding pulling the arms and club back down in front of the body as you keep rotating to face the target. The arms and club do NOT pass the body rotation until you are facing the target. Watch this
