Swaying

This can produce some terrible shots because it is very difficult, after swaying back during the backswing, to bring the clubface to the ball in the proper alignment.  

Although there is some slight head movement during a swing, any significant side-to-side (or up-and-down) head movement should be avoided.

To get the right feel, hit some practice shots with feet together.

During your weight shift, concentrate on keeping the weight on your right foot on the inside of your foot.

Check your progress by taking practice swings with the sun behind you and watching your shadow.

Don’t let the clubface get ahead of your hands at impact.
