As I've said before, I definately wouldn't structure a routine based on those results. For example, I understand why they'd say that pushups stimulate the pecs more than other exercises such as DB presses, but I'd still take a 100 lb DB press over some pushups any day.

I knew I recognized that.

I agree. I think it's interesting but it doesn't go much farther than that. Hell, leg extensions are only 2% below the squats. And functional compound exercise win out any day, despite the fact that some isolations will show more "activity" in a certain muscle

If you act sanctimonious I will just list out your logical fallacies until you get pissed off and spew blasphemous remarks.

^^^ i agree. that and leg exstentions are bad for your knees if done wrong, but then again so is everything...

Studies are all well and good but I will take compound movements any day over isolations no matter what the studies say about "activity" in the muscle.
