Have you ever found success -- and I mean, something you really consider crucial -- by following a principle you discovered on your own, one which goes against bodybuilding custom, or isn't often talked about?
Examples of the former might be, gal and no one utterly denying the "eat big to get big" principle, or dorian's "machines are better than squats", or those people who don't use test in their stacks. As for the latter, I remember some huge mofo from the T-nation forums who swore by hammer strength machines, really couldn't live without them -- I mean, yeah, lots of people like hammer strength, but hardly anyone would claim they're the be-all-end-all of exercise.
