Query: Excellent tips from a golf master.

I enjoyed reading this book. It is very intuitive and encapsulates the fundamentals for a beginner into a few short and easy to remember tenets. However, upon to taking some lessons, it turns out the swing methods advocated in this book are a bit outdated. In fact I was taught diametrically opposite techniques. So, something to look out for. It seems this swing as taught by Ben Hogan assumes you are already in great physical shape and have some body flexibility honed by years of practice. Which is not true obviously for a large fraction of players.
