Many golfers overlook their posture¹. Rather than take the time to see that their weight is properly distributed at address, or that they have the right amount of forward tilt², they set up to the ball quickly and carelessly and simply let it fly.

　　If this is your preshot pattern, slow down! You need to pay more attention to your posture. If you don’t, you’ll have a hard time maintaining your balance and keeping the club on the desired swing path. On the other hand, the better your posture is, the more likely you are to move everything properly during the swing, and thus build clubhead speed and power.

　　Good posture is grounded in a forward tilt from the hips³ -- not the waist -- of about 30 degrees. If you’re not sure how much 30 degrees is, picture yourself standing⁴ in the middle of a clockface. If your upper torso is the top hand, it should point toward one o’clock. Think of this as your swing’s "Happy Hour:" You should maintain it for as long as you can, from your backswing to your finish. This posture prevents you from moving up or down during the swing, and helps guide the club on the correct path, which is at 90 degrees to your spine⁵.

　　Why 90 degrees? If you were to attach a ball to a rope and swing it around in a circle, it would move fastest when it’s rotating at 90 degrees to your arm. The golf swing works by the same principle: For the club to move its fastest, it must rotate at 90 degrees to its axis⁶, which, in this instance, is the spine.
