This post is about how your swing plane can affect how your wrists cock and uncock during your downswing. How you think about your swing has a lot to do with your mechanics and how well -- or how badly -- you manage to keep your swing working.
I spent a fair amount of time talking about wrist cock in the elbow posts. I divided wrist cock into two parts:
- The first was sidecock, the wrist movement you use if you make a karate chop with the side of your hand.
- The other I dubbed backcock, where the back of your hand hinges toward your forearm.
One of the reasons sidecock is a challenge has to do with your swing plane. Most of you know that your swing plane can be either flat or upright -- Dufner has a flattish swing while Bubba's is wildly upright, for example. If you're somewhere in the middle, teachers will often refer to that swing as a neutral swing.
But the part of your swing from around waist high down to the ball -- the impact zone -- acts pretty much the same no matter what your plane looks like. And that probably needs some explanation.
Here's the picture of HaNa Jang that I used in a lot of the elbow posts, showing her as she enters the impact zone:

At this point, your wrist cock is mostly backcock. Backcock is the easiest way to chip, which is the way Pete Cowen, one of the top instructors on the planet, teaches chipping. This post included a video where he demonstrates the technique. And as you swing back to the position where HaNa Jang is in the photo, you bend your trailing elbow and that brings your backcocked wrist up into the position she's in.
Is that clear so far? No matter how flat or upright your plane is, at impact you're still swinging the club out away from your body as you turn and shift your weight to your lead foot, so you get the same basic rotary motion regardless of your swing plane. The distance your club travels in the impact zone is pretty much the same for an upright or a flat plane.
However, it's different with the upper part of your downswing, depending on how flat or upright your swing plane is.
- In a flat swing, the down part is roughly the same as the around part. That is, you travel downward very close to the same amount you're moving toward the ball in a flat swing. Because of that, backcock is responsible for a lot more in a flat swing. A good example of this is a two-handed tennis forehand, where it's all backcock and there's no sidecock at all, simply because your arms travel parallel to the ground throughout the stroke.
- But an upright swing travels more down than around. Because of that, you create a lot more sidecock in the upper part of your swing. The backcock becomes most pronounced as you near the impact zone, simply because the momentum of the clubhead tries to stay on the plane as you come down. You try to turn, the momentum resists, and your trailing wrist bends backward more as your body turns to face the ball. Otherwise the club would ALWAYS come over-the-top on the way down.
In the elbow series I focused on a flatter plane swing -- which most modern instruction also teaches, so most of you are probably more familiar with it -- because the swing is simpler to understand. I have an upright swing so, although I use a lot of backcock in the swing, I use a lot of sidecock as well. But my understanding of my swing -- my swing image, if you will -- uses lead shoulder rotation (which I talked about in the first few elbow posts) to smooth out the transition from mostly sidecock to mostly backcock during the downswing. That's a lot more difficult to explain in blog posts although the drills would help you create the move, even if you didn't understand it.
The purpose of this post is much simpler. I just want you to understand that, if you have an upright swing and you're having trouble getting backcock early in your downswing, there's nothing wrong with you. But you should be able to use backcock in the impact zone with little or no trouble. If you're having a problem there, it's just a matter of understanding how your hands and wrists work during impact, and working with the drills in the elbow series will help you develop that understanding by "digging it out of the dirt", as Hogan would say.
I hope that clears up any problems you might have. As usual, you can post questions in the comment section and I'll try to answer them.
