In my experience these books are less than useful most of the time. It's important to remember that these guys are not just juiced to the max, but are genetic freaks to begin with when it comes to recovery. Basically that means their workouts are sort of useless for normal people. It might have some interest as a read for you just to see what he's doing, insight into his life and the BBing world, but I doubt there's anything in there you could actually learn that you can't learn on the net for free.
