True, but shoulder-width is pretty damn narrow. I don't know that many dudes that do narrow stance squats unless they're specifically targeting the quads. And theres leg extensions 2 behind. :rofl:

Nice post, but I'm curious as to where these numbers came from.

while it would seem to be "common sense" I don't believe there are any direct studies of the link between fiber activation and hypertrophy, other factors may (and probably are) be involved that mitigate the importance of this to some degree.

Also, if you are trying to develop strength, isolation exercises typically have no carryover to sports performance.

While that might be true, you can use compound movements that will stimulate move muscles at once.. what I would like to see on this is the degree at which one exercise stimulates secondary muscle groups... like squats on all the muscle groups in the lower leg.. that I think would be very useful information also

I know some PLers who love things like push downs, and skull crushers for carryover into bench, and things like GMs and ab work for deads and squat. i consider those isolation. But ultimatley, althogh I do like to lift heavy weights now and again, PLing isn't my "goal" :D

Oh, and those studies that link "activation" to "hypertrophy" that you're looking for are probably classified under weight training :rofl: just messin' w/ ya :D

Nice post indeed. I wish more of the muscles in the back were covered, specifically Rhomboids.

Okay, all I found out is that it was published by these two:Tudor Bompa and Lorenzo J. Cornacchia

And, I *think* it was in this book: "Serious Strength Training"

Any updated on this or rather anymore additional information? Particularly what Matt D said about secondary groups and the comparisions of compounds to iso's and the like?

Anything other info that pertains to this basically? :D
