David Henry got big on DC. Mentzer, Viator, Dugdale, and Dorian on HIT variations. Arnold on volume, but his best on volume with intensity. Johnny Jackson and Eric Bui by powerlifting. Serge on lots of volume. They all found what worked best for them. They all tried various styles of training, saw the results that they got, and eventually found what their body responded best to, in both ecercise and diet. Dorian carefully logged and measured everything about his diet, Darrem plays it by ear.
There is no "one" method to getting big. There is what works for you the best, which may not be what works for someone else the best. Adonis isn't revolutionizing bodybuilding, he's just presenting his variation on it. Which is pretty close to a lot of other guys' variation. Same with Dante. Though he hates having it categorized as HIT, it's very similar (I think it's actually remarkably similar to a hardcore version of the Body for Life program). You can argue how much better one system is over another till the end of time, but there will never be a resolution. For every person who got awesome results training one way, there's someone who didn't get any.
Adonis's principles work for him. Awesome. DC's work for Dave Henry. Awesome. Each and every one of us has what works for us. Talking about different systems can be educational and rewarding, and certainly trying out different things is the best way to find what works for you. But argueing about what system works best is just retarded. There is no best, just different.
