For what little my opinion is worth, I bought Ross's Ultimate Training for the Ultimate Warrior book a few months back and have loved it. It contains a ton of different workout ideas with a bunch of very intense sample workouts. This guy knows how to bring suffering to those who take it on. This book is his sandbag lifting book, but also has alot of bodyweight PT, sledgehammer swinging and sled dragging work just to make life interesting. He is a boxing coach so there are some workouts that have that flavor, but I think his workouts would be good no matter what your goal. He also has running advice and running workouts in his book. Overall after having Pavel's PTP and Kettlebell book, having read the naked warrior, and owning Furey's book, I would say this book makes all the others obsolete. Lifting a sandbag is tough work, and they are cheap to make which is nice. The other book I hear great things about is Underground Guide to Warrior Fitness, all bodyweight PT in this one from what I hear, but I have never heard a negative word spoken about it. Here are some links for you all.
