Roll to a coil
By T.J. TOMASI
“Golf is best played on the inside rims of your feet.”
Jack Nicklaus said it, but he received this advice from his teacher, Jack Grout, who got it from Alex Morrison, the scion of much instruction that is accepted today. Morrison was one of the first to emphasize the importance of rolling the ankles in the golf swing.
How it works
The ankle is a hinge joint with a range of motion that allows the leg to move inward toward the center of the body while the foot remains essentially in place — a key move in a correct backswing.
This rolling motion is rarely used in everyday movement since it is much more natural to lift your front heel and knee in line, a habit ingrained from walking. This is why so many golfers simply lift their front heel and knee straight up during the backswing, thus ruining their coil.
Roll your ankles
On the backswing, your left ankle (right for left-handers) folds inward toward the center line of your body in response to
the pull of your front knee as it moves behind the ball. The knee should move inward rather than directly upward.
