The stack and tilt golf swing isn't exactly new, it's already been around for nearly 3 years, it's just taken some time for you to hear about it!
The stack and tilt swing is the brainchild of Andy Plummer & Mike Bennett, two pro golfers. What they basically did is to study the golf swings of all the good players and see what parts of the swing they all had, what some of them had, and what none of them had. They followed this process with average golfers and total hackers (that's you and me). From that information they compiled a swing that gives you the best combination of distance and accuracy, but above all it improves your ball striking and makes you far more consistent. They found out why people hit it well and why others didn't and put that evidence into a swing, a simple swing.
In the conventional golf swing, that your local pro might teach, you are required to shift your weight to the right side, coil like a spring, then uncoil through the hitting zone whilst moving your weight to the left side before finishing posed on your straight left leg, looking like Nick Faldo. If you can't do this perfectly everytime then you are going to be INCONSISTANT.
Stack and tilt is more like "turn,... and go left". Easy huh?
Stack and tilt is becoming more widely accepted in the golfing community, most local pro's will have heard of it by now, even if they don't know much about it. Golf commentators on TV mention it during coverage and lot's of professional tour pro's are using it, or have certainly incorporated elements of it into their swings. This in itself might not mean much however you have to remember these are people who actually make a living from golf, it pays their mortgages... and their private planes! They don't change their swings very often, they've been playing the game all their lives, they KNOW what they are talking about.
Stack and Tilt is becoming a serious alternative to conventional thinking, and it's early days still, it'll be a few more years until the most stubborn golfers even consider that it might work, regardless of results. A quick example of just how difficult it is to become widely accepted.. (and yes, I've seen this example used elsewhere)...
In 1968 highjumpers used to go over the bar using a 'scissors' style jump, a straddle or a 'Western roll', and then along came a chap called Dick Fosbury. His technique of leading with the upper body, thereby increasing the leg thrust, truly changed the sport at the 1968 Mexico City Games. Despite scepticism from judges and coaches, Fosbury cleared every height up to 2.22 metres without a miss and then achieved a personal record of 2.24 metres to win the gold medal. By 1980, 13 of the 16 Olympic finalists were using the Fosbury flop.
12 YEARS LATER and 3 people were still using the old method! Yes, I know, it's unbelievable! but that's how people are, and it's not as if Stack and Tilt is that cut and dry, if it were then Mike and Andy would have you sitting on your hands and hitting the ball with your legs! So, accept it, there's going to be scepticism for quite some time. Sure you'll meet people who say "Yeh, I tried that but it wasn't any good", but did they REALLY try it? In what way? Who showed them? Just how much did they try it? For how long?... and how good is their swing without it?
Anyway, back to the Stack and Tilt golf swing, it's a coming together of information about the swing, it's nothing new, just a study of the evidence that's already there, most of it already being used by todays top golfers all over the world.
To get you started with just ONE fundamental, here's a couple of pictures to help you make up your mind as to where you want your golf game to go for the next 20 years.... stuck over that right leg fatting and thinning shots?
Jack Nicklaus

Ben Hogan

Tiger Woods

As you can see, I've drawn some lines from the feet to the hips to show how the teaching pro would have you position your right hip over your right foot, moving your upper body away from the ball.
If the true professionals/greats of the game don't do this then why should you?
This is just the first step in understanding the stack and tilt golf swing.
The Stack and Tilt golf swing looks at all the golf swing's fundamentals (modern technology has allowed this) and creates a far more effective way of hitting the ball consistantly than swaying over to the right side away from the ball.
