Book excerpt: Most golfers seek to get better by making their swing as simple as possible to produce distance, control, and consistency. The ESPY technique is like riding a bicycle: once you learn, you don't forget. Based on fundamental sprocket mechanics, the ESPY is an acronym for three simple Ergonomic movements, consisting of the Synch, Protract, and Yaw elements. The E is the ergonomics used to set up each S.P.Y. element of the golf swing. By learning what these mechanics are and how they create power, speed, and control, you'll be able to: control backspin, loft, and trajectory; eliminate the negative effects of downtime and nerves; overcome common obstacles to develop a consistent swing
