There are 5 generally accepted putting factors which occur during the moment of impact between the putter head and a ball:
So the perfect putt is one where the putter head is traveling on a line directly towards the hole with the putter face perfectly perpendicular to that line, then hitting the ball in the exact center of the club head using an upward stroke which has enough force to get the ball to get to the hole.
Easy? Yeah, right. But the Putting Alley allows you to practice, isolate, and focus on these five variables to make the perfect putt. They all come into play, so by simply practicing regularly you will learn to hit better putts as you begin to roll the ball into the hole.
Although the Putting Alley is built for short putts, by concentrating on these factors you will find that your long putt game will dramatically improve. Getting the first few inches of the backswing correct, for example, is a great thing for short or long putts.
