I can’t get enough putting drills! We will call this a “Step Back” line drill. I like to set the balls at 3, 5, 7, and 9 ft. This drill helps your feel and green reading skills. As you step back, you must adjust the speed and starting line of each new putt. The goal is to make all 4 balls in a row! Start over if you miss a putt. No Pressure. Once you complete the drill, set up on a different angle for a new challenge. Improvement is never ending! Have Fun.
