The benefits of Stack and Tilt are easiest to see when comparing the swing to a more traditional approach [source: Plummer].
- Keeping your weight on your front foot improves consistency and puts the power where you want it. A traditional swing requires you to shift your weight to the back foot on the backswing and then back onto the front foot on the follow-through. Many golfers find this hard to do consistently, so they end up hitting off the back foot instead.
- Tilting the spine forward at the top allows your shoulders to swing in a circle, keeping the swing clean and maximizing its force. Called by some people a "reverse pivot" or a "reverse shift," tilting forward is the natural posture when you turn your shoulders in a circle while keeping your body centered over the ball.
- Sliding your hips helps prevent slicing and provides more power to the swing. Golfers are traditionally taught to turn their hips through the shot, but that can pull the club across the ball. Sliding the hips lets you hit a gentler curve while also shallowing the club descent and setting up your body to support the swing -- all of which adds up to a more solid strike.
- Releasing the forward tilt of the hips adds power. We are often told to keep our hips in the same position during the swing as they were during address, but this limits rotation and kills momentum. Just think of how a baseball slugger uses hip release to generate power.
- The hip-thrust and spine-stretch lengthen arms, resulting in a truer release. As the spine tilts back and the hips slide forward, the arms must stretch, adding rotational power and more effectively releasing the stored potential of the address stance.
Peter Finch, senior editor of Golf Digest, reported hitting the ball at a lower angle and about 10 yards farther than usual. He said that his shorts were closer to dead center on the clubface and that he felt a "noticeable difference in compression" [source: Finch]. Still, there is no substitute for the hands-on approach, so why not give stack and tilt a try for yourself?
