Re: Common causes of the push shot?
I am a 14-15 handicap and fight a push (straight right) and push fade (starts right but goes even farther right) all the time. Here's what corrects it for me, when I go back to basics. The back swing is initiated by starting to rotate the upper body. If you move your arms, hands or anything else, you're already off plane. There is a triangle formed from shoulder to shoulder to the hands - try and maintain that triangle on the back swing for as long as possible. Do not rotate, turn, pull (whatever) the arms and hands anywhere but where the triangle leads them. The crucial point in the back swing is halfway up - the arms are parallel to the ground AND point down the target line, the hands cock the club exactly 90-degrees to the forearms.
You can practice this in slow motion with any club in any room. Start the swing by rotating your upper body - maintain that triangle. Get your forearms to parrallel to the ground and pointing down the target line. Repeat this in slow motion until this is where you end up every time you begin, with a rotation.
Full swing - continue to rotate the upper torso through the backswing, your left hand should feel like you're pushing the grip away from you ( the club should "cock" now). The instant your left arm bends, your backswing is done. Beyond a straight left arm is "over the top" time - fade, slice- ville. The final rotation of your backswing is rotation of the hips, not swinging of the arms. If you can't get on this plane back or your left arm breaks, there's no way your downswing will be on plane, nor will the clubface be where it was when you started at address.
Review - start with rotation of the upper body - lower body quiet; forearms parallel = down the target line; push the grip away with the left hand; rotate hips through the top; left arm breaks = slice or push fade, always.
If I remember to do these things on the way back, I have a better chance of hitting the ball straight. That's what I work on.
