Know your Swing is on Plane
It’s as easy as telling time

Check This!
WHILE WEARING a wristwatch, start your swing and then stop it when your hands reach shoulder height. Look back and see if you can tell the time on your watch.

What You’re Looking For
Proper forearm rotation. If you can’t see the face of your watch, you’ve taken the club up on too steep a plane. That can lead to a slice.

How to Stay on Plane
Instead of taking the club straight up, swing it around your body in an arc, like a satellite in orbit. That doesn’t mean whipping the club to the inside with your arms. Rotate your left forearm as you swing your arms up in front of your chest. Now you can attack the ball on an inside-out path—the key to pure shots.
