I love Mark Hatmaker's stuff. Really. I own about 6 of his books. They're all great.
BUT...his conditioning book was atrocious. I was really excited for it to come out, and got my hands on it right away. My initial impression was positive, but I think that had more do to my excitement and being dazzled by dozens of new exercises I'd never seen before. I even gave it a positive review on the forums. What can I say, I was young, easily impressionable, and probably still thought there was a secret to getting "MMA strong."
The longer I had that book, the more senseless so much of it seemed to me. Too many ridiculous exercises, lots of flailing of light weigh, poor programming (if you could call it that), a laughable nutrition section...yeah, I sold it.
Now I only have awesome Mark Hatmaker books.
I will say, however, that I am on his E-mail list, and occasionally he has workouts in them. I have seen some decent looking stuff in there. Maybe he's changed his views about things.
