I understand what you are saying, I just don't discount the benefit of using different techniques to build muscle.
That IS what I'm saying, too.
Take a picture of your chest right now, with no shirt on, and for the next 8 weeks only use crossovers for your chest workout, that's it, nothing else.......then in 8 weeks take another pic of your chest and compare the two. If you've made improvements in MASS, I'll believe your every word, if not, admit you were wrong and you have a lot to learn........deal?
Again, maybe we're approaching things from two different angles here, but we are agreeing. Maybe I'm just not too clear on getting my view point across.
