You can see his book there in the corner. He's the guy I took my trainer cert thru. He's prolly forgotten more than we all know together. Plus he's legit in his research as well. He calls it like he sees it, and won't BS either.
Worth the cost of the book if you want the straight scoop. And it just came out within the last year....
