In reply to GLO:
I've been using it for the last few months. It's worked well for me, he's good on the tactics / mental side and there are loads of good exercise ideas including core / antagonists etc. I haven't read the Anderson brothers' book but it might cover a lot of the same ground? A friend who had both seems to be using the Horst training plan so that might say something though. He has some spreadsheets up for free on his site with training plans on them that might be worth checking out.
