Players have managed to play well with a 'Hitting From the Top' action despite this flaw. But because some players are athletic enough to make a compensation move, they can get away with it, which doesn't make it any less disastrous for the average golfer. No one has found an instant cure for this particular ailment. Here is a list of things that cause Hitting From the Top; your grip is too weak, especially the left hand. Misuse of your forearms, meaning the use of the wrists instead of the forearms at the beginning of the backswing and at impact.
Aiming to the right could also be a cause together with having a stiff leg at impact. Top players are least likely to hit from the top as they keep their knees slightly bent as they come through the ball. Telling a student to hit against a strong left side used to be the common teaching theory but straightening the left leg throws the club out and over the correct swing path.
To demonstrate this point, make a slow-motion swing keeping your knees slightly bent until after the ball is hit. The club will stay inside. Take another slow-motion swing and straighten your left leg about halfway down. Your upper body will throw itself out and over the ball.
