A golf swing plane that’s too flat (horizontal) is sure to cause some ugly hooked shots. While some players take the club back on an overly flat plane, for others the problem is caused by a poor weight shift.
If your weight moves onto your right (back) foot during the downswing, the club follows a shallower path to the ball and the clubface shuts, causing a pull or hook. Any time you hit one of these shots, check your balance at the finish. If most of your weight is on the right side, there’s your problem.

You can utilize the same drill to fix many swing problems, including fat shots, slicing and a lack of power.
