Understanding the "Stack and Tilt" Golf Swing

In the most recent issue of Golf Digest (June 2007) there is a detailed description of what is called the "Stack and Tilt" swing. This golf swing is being promoted by golf coaches Andy Plummer and Mike Bennett.

Predictably the article indulges in a bit of exaggeration when the author says "Their secret...contradicts almost everything being taught in the game today." But the Stack and Tilt swing does introduce some changes to the way we're used to thinking about the golf swing, and some of them may actually help you play golf better.

The Biggest Difference

The most important difference with the "Stack and Tilt" swing is the way it encourages golfers to keep their weight forward - on their front foot during the entire swing. Stack and Tilt does away with the normal "weight shift" concept during the different parts of the swing. With Stack and Tilt the golfer starts with about 60% of her weight on the front foot, and presses even more weight towards the front when taking the club back.

Some older golfers will think this looks like a "reverse pivot" where the golfer seems to be leaning towards the target at the top of the swing. Teachers of the typical modern swing have their golf students draw the club back and stack their weight over their back leg when the club hits the top of the swing. But Stack and Tilt encourages the golfer to lean towards the target while the club is taken up.

Subtle Differences

For many golfers it may be hard to spot the differences at first, but there are some significant ones. For one thing with the typical modern swing the back leg remains bent with a slight flex at the knee. With the Stack and Tilt the back leg straightens out. The photos featured in the Golf Digest article (p.122) demonstrate how the back leg straightens out as it pushes back towards the target.

As a result the front side of the body is "stacked" over the front foot, and the trailing side of the body is "tilted" towards the target.

For a comparison with the typical modern swing look at photos of Tiger's swing of the last few years, or see the photo of V.J. Singh's swing on page 43 of the same issue of Golf Digest. Singh's upper body is "stacked" over his back leg at the top of the swing, and the trailing side of his torso is perpendicular to the ground as he pushes his weight back over his back leg. This is quite different from the way the torso is angled towards the target with the Stack and Tilt swing.

Shades of the Past

If you are familiar with the teachings of most modern golf coaches this may sound like a radical departure from golf orthodoxy. But the fact is, there have always been alternative schools of thought which questioned the simplistic "weight shift" idea. In particular, look at old photos of Jack Nicklaus, Ben Hogan or Sam Snead. None of these golfers make the major shift over the back leg like you see with Tiger Woods, for instance.

Or have a close look at the famous 1930s videos produced by Bobby Jones. There is no obvious shift towards the back leg. Jones remains centered over the ball throughout the swing and is more concerned with rotation around the center point than he is with the lateral weight shift characteristic of the typical modern swing.

Can Stack and Tilt Help You Improve?

Having said that, there are several interesting points made by the advocates of the Stack and Tilt swing, each of which may help the typical golfer having trouble hitting the ball squarely and powerfully.

The first is the lack of emphasis placed on the weight shift. For many golfers this idea is misleading and results in a lateral shift that basically turns the golf ball into a moving target. Shifting one's weight to the back also results in a "shallower" swing which increases the chances of bottoming out too early. Depending on a variety of factors this can either result in fat shots or thin ones. As an alternative, pressing into the front foot as you take the club back very definitely forces a steeper approach to the ball and should result in fewer topped shots. It also results in a lower trajectory since it de-lofts the club, and this may give you greater run on certain kinds of fairways.

The second has to do with the position of the back elbow and the flatter swing advocated by the Stack and Tilt teachers. A flatter swing is a more rotational one, and in advocating a more rotational movement the Stack and Tilt theory has something in common with other "alternative" swing concepts like the Single Plane Swing recently adopted by Tiger Woods (compliments of Hank Haney.) I'm not sure why a flatter, rounder swing is essential to the Stack and Tilt swing, but I suspect it has to do with the relative difficulty of getting the club going when you have your weight forward. In the jargon of some teachers this weight forward position is what might be called an "unathletic" one. So the idea is to maximize club head speed by taking advantage of the rotation of the torso.

And third there is the intriguing idea of the "pelvic thrust" which the Stack and Tilt guys claim is necessary for a couple of interesting mechanical reasons. The most important one is that since one's weight and shoulder position are forward, the approach to the ball will be significantly steeper than normal. In order to "shallow out" the swing you have to whip your hips around and thrust your lead hip up and towards the target. This makes you feel like you are almost jumping up and striking the ball while on your toes. If you have seen those photos of Natalie Golbus or Sergio Garcia, or a younger Gary Player you have some idea what they are talking about.

The best way to see if Stack and Tilt has anything to offer your golf game is to just give the "weight forward" idea a try. Just set up with noticeably more weight on your front foot, and then as you take the club up press more weight into your front foot. It should feel quite different from what you are used to, but it should result in fewer thin hits. Unfortunately it may also result in more pushes, especially with the longer clubs. The easiest fix is to adjust the positioning of the ball by moving it slightly forward. You may also find this swing more complicated and more physically taxing - and for most of us that will be enough to keep it on the shelf.
