I haven't either, but I HAVE seen a lot of BIG guys hammering out a LOT of volume. Now looking at the phase II of Korte 3x3, the volume drops off drastically. I think it's creating some mitochondrial growth, conditioning and a bit of fatigue training (for whatever reason) before hitting the big stuff, and does not HST do the same thing? Yup. Also, there are some similarities between this and the Madcow 5x5 intermediate training, which makes you strong; very strong. I'm not sure what to call it, but rather than a "muscle confusion" bag of crap, it's a systematic process doing a few different things using the movements you're trying to improve. And I REALLY believe in that. You wanna hammer 60 nails a minute? Get a hammer and nails to practice with.
