Or do you think that, through experimentation, most bodybuilders found that by using both compound and isolation exercises gleaned better results than just using isolation (or just compound) exercises? Certainly the anecdotal reports of the great value of compound exercises abound in bodybuilding.
I would encourage strongly considering the latter possiblity. I think that in weight training (particularly for a person with some scientific understanding of the human body) there is a tendancy to want to be an engineer (inventing and designing new systems) as opposed to a biologist (observing and figuring out the way things work). I think that being 75% biologist - and humbly keeping in mind that through trial and error performance athletes have probably stumbled across some very effective ways of doing things - is pretty reasonable. At the same time, there's nothing wrong with applying knowledge of anatomy and physiology to make that anecdotal experience that much more applicable to your situation - but to supplant large amounts of anecdotal experience with mere theory is a risky proposition.
Of course, actual evidence-based decision making is optimal, but as we've discussed before, well-designed studies reaching valid and applicable conclusions are rare in this sort of thing. If only pharmaceutical companies had a financial interest in performance research - I would love to see some nice "n=250,000" studies on this!
