This is one of those drills that takes care of a lot of issues with your putting. You’ll find that as you practice this, you may want to make it part of your actual putting routine on the course because if it’s good enough for Rickie Fowler and Jack Nicklaus, it’s probably good enough for you.
You’re going to hover the putter ever so slightly off the ground, which helps you swing the club freely back and through. This will also help you to create a more centered balanced position at setup. When you get the putter gets jammed into the ground, it can almost hold our body up to some extent, which makes it hard to get the putter swinging.
