Max is a 15 handicap who gets to play between 15 and 20 rounds per year. I would classify his motion as a decent player's version of the classic over-the-top swing. His good shots were pull fades and his bad shots were duck hooks, huge slices, tops, and even shanks.
What you'll see in this video is a before and after of a couple hours of work together. We tightened his back swing and worked hard on his wrist angles on the downswing to give him a better chance of delivering the club from the inside.
