I must assume the book was 5 Lessons by Ben Hogan? Probably the finest book ever written concerning the proper fundamentals. To this day it is still one of the top sellers.....we are talking over 50 years! Is there any serious golfers out there that haven't read this book? If you haven't do yourself a favor.........simplicity as Genius!
No it's not a joke?

Yes the book is 5 lessons. Absolutely brilliant. My grip has always been the biggest problem but this book has helped me so much.
