I guess the reason I usually don't emphasize training as much is because for me personally, I can grow or get stronger on nearly any training routine I do. It really doesn't matter if it's built around volume, high intensity, etc., as long as I'm training hard, consistent, and following some of the basic principles of progressive overload, I am going to get bigger and stronger. That's why I never really liked getting into the discussions around the different styles of training because my belief has always been that as long as you're training hard and doing it right, it'll work.
But you're right.... I mean there are some people out there who have a variety of training issues from not understanding progressive overload, not training hard enough, not being consistent, etc. But if you can get the basics down, then most routines will work... or at least like I said, they almost all work for me. Maybe I'm just lucky and respond to any type of training. But if my diet starts to slip then forget it. But if my diet is on target, I can do nearly any type of training and get results.
