Guy who has posted here and posts a lot on the HST boards and owns the hypertrophy-research boards has this site going. http://hypertrophy-research.com He's also got a 21 page PDF free ebook out right now explaining the method more in depth. Thought I'd share the site with you guys. I haven't tried the method he outlines here yet, but I may try it in a couple months when I'm done with my current 5x5. Also check the forums for the Q&A, lots of information there.
