Very dry reading alot of times. But the most scientific books you will find. These guys coached all of the Russian Olympic weightlifters of the past when they were dominating and pretty much all olympic weightlifters and powerlifters today base their training off of their books today.

If you give me your email addy, I could try to send you a bunch of PDF files by Scott Abell. I have alot of his training and diet stuff saved. along with audio interviews. He is very scientific.
