LOOKING BACK At the top of the swing, you should easily be able to look over your right shoulder.
The problem with golf is, a well-intended swing tip can cure one problem but cause another. Take the backswing. One thing you might have been told is to "keep your head still" to prevent you from changing your spine angle during the backswing. If you fixate on this thought, it can cause a tilted shoulder turn, which leads to a reverse pivot. A simple check at the top of your backswing can fix this problem.
Grab your driver, and swing to the top. You should be able to turn your head around, look back over your right shoulder, and see your right arm bent 90 degrees at the elbow. Now you're in position to swing down on the proper path for solid contact.
