The correct pivot in your backswing is critical in helping you to deliver the clubhead powerfully into the ball at the correct angle and therefore giving you a chance to hit that great shot.
Below is a great swing image to have, Ric is demonstrating with the use of some lines how to turn on “the balance line”. Turning correctly on the backswing will see a very minimal amount of your body visible on the target side of the line at the top of the backswing. Pivoting correctly like this perfectly “loads” you up ready to power forward into the ball.
