If you are a Pure Swinger, i.e. one who lets centrifugal force square the club, you could hit pushes if the ball is too far back in the stance, especially with the driver. This kind of swinger has to find the exact ball position, usually near low point, to produce a straight away ball flight.

If not a Pure Swinger, it could be a grip that is too weak, or poor hinge action.
