To be truthful, when I was doing EDT, I screwed up and kept using too much weight, so I didn't really quite notice a lot of hypertrophy (I probably had more "muscle density" than actually gaining visual size). That, and I totally bombed my schedule. I kept getting knocked out of my routine, so it didn't work all that great for me, but it was my fault. I figure if I use lighter weight, and do it the RIGHT way, then I'll actually get some really good results, but first I'm going to try Waterbury's singles club for 4 weeks (I like the low rep stuff...hehe).
Hope that helps a little bit.
