Got the book a few weeks ago.
Generally well written with mostly scientifically justified advice, but some of the training appears rather flawed, and some totally unrecomended. I also found the quotes at the start of each section totally pretentious.
It's biggest problem though is that it just isn't specific enough for bouldering. I've said it before, but training for bouldering is not the same as training for routes, and the book tries to cover the whole range up to alpine routes.
