David Leadbetter has an outstanding book that lists the 80 most common problems in golf. During our practice sessions over the past few weeks, I noticed some of these faults  and have put together a few pages from this book showing both the fault & fix.  I hope that these, together with the relevant drill will help you improve your game. I added this breakdown of how to practice as I am sure you will be spending time out on the practice range by yourselves during the season and this is a good routine to follow!
