This book was certainly worth the price! It's over 300+ pgs of some of the best MMA advice out there. It starts off with a mini biograhpy of B.J. Penn then goes right into the good stuff. Penn goes thru everything from striking basics to brazilian jiujitsu wizardry in well sorted and easy to follow chapters. The pictures that he uses to illustrate the moves are also great. Most come with several angles of the moves he is demonstrating and are very easy to follow with his great insight on each and everyone! I recommend this book to any who wants to get that edge in their MMA training whether it's for competition or simply to stay one step ahead of their training partners in the gym.
