Ah, now you two seem to be jumping to conclusions here. I've never said only do one exercise for each muscle group, although you could probably get away with it, providing you chose the "right" exercises.
Now this is a chest debate, so let's forget other muscles for now. There are slight exceptions (deltiods for instance.)
Now, why do extra exercise for chest? I've discussed this to quite a degree in past threads so i'll sumemrise it now.
Flat bench, for instance, is a great exercise. Only problem is that there are "weak links", as with any compound movement. Therefore, delts may give out before you've given your chest enough stimulation to instanciate growth. So i do weighted dips because it stresses my front delts to a lesser degree and also puts my tris in a stronger position. This exercise also aids my overall pushing strength and can assist my bench progression. Then i may move onto flyes because it's the closest to isolation you can get for the chest. This takes almost all of my delts and tris out of the picture and allows more focus on the chest. Not to mention that "isolation" tend to be good for local IGF-1 release.
By now my chest workout is done and i'm either good to go home or good to start on another muscle. Seems minimal, i know, but as long as i know i'm progressing then i know i'm growing, broadly speaking.
This applies for every bodypart i do. The back is collectively several muscles so several exercises are beneficial to effectively stimulate growth in all muscles. Not to mention arm muscles again being the weak links in pulling exercises.
Lower back and abs tend to be weak links for squats, so leg presses or hacks or extentions etc.. are performed.
Triceps only need one exercise cause, even though they have three heads, they only have two insertion points so the triceps either contracts or it doesn't. Simple as that. Whether you can stress one head more than the other is irrelevant cause it won't cause growth of any significance. Biceps have two insertions and either contracts or doesn't. No peak or lengthening can be done.
Deltoids are a different story though, but that doesn't really need to be addressed.
TJohn, why are you not liking it? Once you grasp that you don't need to do that much then you'll realise you can spend less time in the gym breaking yourself down and more time resting and growing.
