You can do the drill with the club right in front of your body to allow you to see what is happening.
You see the pros shallow the club into the perfect slot, and hit one great shot after another.
So why is it that most players can't seem to stop coming over the top?
They'll steepen the club to start the downswing, and lose tons of distance and consistency.
Most of this comes from confusion of exactly what you should be doing with your hands and arms to shallow the club.
It can be hard to know for sure, since you can't even see the club at the top of the swing.
I am going to solve that problem with a very simple set of drills.
