I was watching a recent PGATour tournament and picked up on a simple key for the putting stroke. Announcers Ian Baker Finch and Sir Nick Faldo commented on a player's stroke and emphasized the importance of "rocking the shoulders". By rocking your shoulders, you take your arms and hands out of the stroke, which is essential for developing a consistent motion. Over the years, I've found this tip to be the most effective "key" for consistent results.
