Full shoulder turn?

[jfrain2004]

Was out for a few shots on the course last week and noticed that after 20 mins of shots that i was starting to hit them sweeter and further and more accurate without any noticable increase in effort. Hell, my 8 iron was carrying over 150 yrds, and leaving such craters on the green I had to stop as was taking too long to repair.
I asked myself what was I doing different and then it occured to me that I seemed to be making a bigger shoulder turn as I got more loosened up and seemed to be getting my left shoulder well behind the ball on the back swing. So making a consicious effort to do this last evening I was back in the groove again from my first shot onwards.
So assuming this full turn was/is indeed the source of my new found power/accuracy/consistency what is it about this full turn that produces this vast improvement in shot making?

The obvious answer is that you are getting more power from a full turn, that helps the distance.

As for the accuracy and better ball striking, I will guess that your turn is helping you to keep from trying to do it all with your arms, which results in coming off a nice swing plane. A bigger turn is probably helping you keep your left arm (if your a righty) straight.

The big shoulder turn gives you more time to accelerate through the ball. With a smaller turn, you do not get as much time in the downswing to accelerate. This is the torque factor that everyone is talking about. The turn of the shoulder creates torque in your body, and the more torque in the back swing is more that you have to uncoil when starting the downswing creating more whip in the club and creating club head speed. And everyone know more club head speed is distance.

The full shoulder turn indicates that you are using your larger core muscles more in proportion to your smaller arm muscles which can (but is not guaranteed to) result in a simpler, more repeatable, more powerful swing.

Definately using more bigger muscles, with much more power behind your swing. I've just recently adapted my shoulder power into my swing cuz im adjusting to my new and improved swing.
