Query: Fighters notebook by Kirik Jenness, David Roy

The Fighters Notebook just has to be the most comprehensive Mixed Martial Arts training manual ever. Quite simply, just like mixed martial arts for competition and self defence, it delivers the goods. With over 600 pages of packed information,the authors manage to pack in information and get the message across in a systematic way. The reader cannot but fail to be impressed by this resource and it's ability to inform their training for years to come. The book has so much information in it that it is impossible to read in one sitting. Unlike many other training manuals I've read, the reader will go back to it time, time and time again.
