How to keep your head steady

Golf Digest, Nov, 2000 by Tom Watson, Nick Seitz

Keeping your head down really means maintaining your posture--that is, your spine angle--into impact. Raising off the ball is typically why people slice. The cure is in your legs.

Strengthen your quads to stay stable

You need strong legs to support your upper body as you swing. Specifically, work on your quadriceps, the large muscles at the front of the thighs. You can use a fitness machine, or you can do an exercise I like that's easy to do at home a few times a day. All you need is a wall.

You sit down, only not in a chair. Stand with your back against a wall, your feet about stance-width apart and a foot from the wall, your arms dangling at your sides. Slowly lower yourself toward a sitting position by bending your knees. Don't go too far down at first--be sure you can make it back up. Hold the sitting position until you start to feel strain--a burning in your quads.

As you get stronger, add repetitions and hold the position longer. Strong quads will keep you over the ball, with your head steady.
