DRILL
THINK HIGH HANDS
As you swing the club to the top, lift your hands so they are as high as you can reach. There should be significant separation between your hands and your head when the club gets all the way back. Jack Nicklaus used to have great separation at the top. This move will make your swing plane more vertical.

DRILL
GO DOWN AFTER IT
As Tiger Woods swings down into the ball, he increases his spine angle by bending over more than he did at the start of the swing. In other words, he really goes down after the ball. If that bend-over move is too daunting, you can bend more at address or during the backswing for the same benefit of a steeper swing.

DRILL
FOLLOW THROUGH TO THE INSIDE
Vijay Singh never lets his arms extend too far away from his body during the downswing. This allows him to swing back inside the target line on the follow-through. To hone this move, put an empty plastic bottle just outside your target line ahead of the ball and hit drives without touching the bottle. You'll have to swing to the inside.

HOOK CURES
A swing plane that's too shallow makes it easy to close the clubface at impact and hit a hook. In addition to swinging on a steeper angle, players who hook the ball have to keep the face from closing.

1. Weaken your grip. The creases between your thumbs and forefingers should be parallel to each other and point toward your chin.
2. Keep your body turning. Through impact, allow your head to swivel with your body pivot, and watch the ball fly. This helps the body to rotate and prevents the face from closing too soon.
3. Delay your forearm rotation. Another good antihook move: Don't let your right forearm rotate over your left until after impact.
