Getting Sync'd Up

So, the other day I was watching the GC, and they were talking about Zack J. and what he was doing in the off season. One of the things mentioned was the 1/2 swing drill, where you start the back swing parallel to the ground, and your finish stops at parallel to the ground.

Last night at the range, I decided to try this, what I found was pretty cool. I used my 50 * wedge, which I normally hit about 100 to 110 yds. While doing this drill I focused on Good contact, in fact, I was hitting the mat fairly hard after hitting the ball, so I figured I was compressing the ball fairly well, what was kinda cool was, I hit almost as far from the 1/2 swing as I normally do with my full swing, i.e. 90 to 100 yds..I almost had to do a double take, to reassure myself that the ball actually went that far, as I was expecting maybe a 70-75 yd carry.

Then I realized, what was making the ball go that far for such a small swing was 2 things..My arms were much more relaxed, and when I got it right, I was pretty well Sync'd up at contact. My relaxed arms, allowed the club to travel faster, I believe, which resulted in a decent carry. After doing this about 25 times, my right wrist started to hurt a bit, so I stopped.

What I'd like to know is, and the low hc folks and Mike, Erik, or Phil can jump in with a prospective, is what I'm thinking, is correct, and if it is, how can I apply this to my normal swing.?   My guess is, my normall swing still needs a bunch of work..lol

I do half swing drills all the time, a good strike will get out to 80% or even more of normal distance. It's pretty surprising.

I'll say it's surprising..

I do this drill all the time with my PW. I hit my PW about 112. If I put the hammer down on the downswing, I hit the half-swing about 100. I have the numbers. The shot just goes at a lower trajectory.

Anyone else have a comment..?
