In addition to all the work I do in higher education, I also love and practice Jui Jitsu. I have been a student of Gracie Jiu Jitsu for many years. I bought this book back in 2002, early when it first came out. I love it, and still read it. In fact, the other night, I was reading it again. I have brought it with me in training sessions with many of the Gracies, including Royler Gracie, Rorion Gracie, and the Late Great Grandmaster Helio Gracie. All of them have also signed my copy of this book. It is a training manual, so you never just read it once, but I am so glad that I have a signed copy, by several members of the Gracie Family, and that the book has travelled with me on many great training sessions with the Gracie family. I love this training book, and the serious of Kid Peligro, Gracie Training books, and I enjoy them thoroughly, and page through them refining techniques in them all of the time. GREAT BOOK. IF YOU ENJOY JIU JITSU, AND YOU DO NOT HAVE THIS BOOK, STOP SURFING THE NET, STOP WHAT YOU ARE DOING NOW, AND GO BUY THIS BOOK!!!
