Triangulate Your Golf Swing
Second Edition - How many ways are there to swing a golf club? Golf magazine writers and TV commentators certainly don't have a shortage of golf swings to analyze. So, I suppose we will never know the answer. This often creates a certain amount of confusion for the average golfer who is trying to improve their game. After years of frustrating golf and countless swing changes, I thought - there must be a simpler way to look at the golf swing. Rather than look at all the differences, I wondered instead if there are things that all professional golfers do the same that average golfers generally do not. Anyone who is serious about golf certainly needs to learn the fundamentals, but the answer I was looking for had more to do with an awareness of what I call "The Principles of Triangulation." Although inherent to all good golf swings, these principles are rarely given priority when it comes to golf analysis. I believe they are at the heart of every good golf swing and at the core of every good golf shot. This second edition continues beyond the first in that it provides the average golfer with more of an in-depth approach to game improvement. New chapters discuss game management, fine-tuning your swing, the mental aspects of the game, biomechanics and more. The Principles of Triangulation have improved my game and I sincerely hope they do the same for yours.
