Perhaps the most important part of the game yet least practiced is putting. I like to spend time working on basic fundamentals for good putting and help students understand how to practice. As with the full swing and all shots for that matter, finishing properly is a key to consistency and results. I use many different tools and practice drills when coaching students as well as video analysis. I then provide students before/after pictures to help them improve.
Below is an example of a student who was very reactionary when putting, quickly coming up out of the stroke after hitting a putt. We worked on building a habit of a solid finish position allowing only the head to turn to see results after striking a putt. Using pictures help students clearly see the difference and make it easier to put the work in to building good fundamental habits.
BTW- This student just broke 80 for the first time shooting 77 on a championship course!
