swaying hips

I have been told in the past that I have a very pronounced sway of my hips in my swing.  Could this be the cause of my current battle with pushing the ball with all clubs?

Sway is a really general word, I dont know how anyone could come to any conclusion about you swing simply by knowing you have a "sway" in your hips.

Without knowing more about it, I can't say.

Is the sway on the backswing? downswing? both?

How much is there?

It's dependent on a lot of variables. A video of your swing would allow people here to really answer the question.

I have a friend that has a sway both in the back swing and subsequently on his follow through to get himself back to the ball. If you sway in the back swing it means that your back knee that should stay flexed and turned around is giving way. This would mean that you may have more of a tilt rather than a turn. If you sway on the back swing you will have to sway that much coming into the ball and will more than likely have the club(s) open meaning that by the time the club catches up to your body and you strike the ball you will push it. The back knee that is flexed in your setup must remain flexed. This provides you with something to turn around in your back swing and creates tension between your upper and lower body that stores your power. Here is the fix that anyone can use. Stand next to your bed or something that is about knee high, make your turn feeling the bed or whatever against your leg. You will turn and feel the stretch in your upper thigh of your back leg.........that is power that you are storing to unleash on the ball. Complete your turn through the ball and you will see and feel the difference between swaying off the ball and through impact as opposed to turning around your back leg and flexed knee and know that the club will be returned as square as you can.
