... not arguments...
Seriously, Squats and deadlifts do have a reputation for making someone bigger.
I believe the reason for this is one of "stress". Knowledgeable people in this field, including myself, acknoledge the fact that muscle growth is a response to the STRESS of training.
Of course, the "anabolic drive" is proportionnal to the stress that makes it possible. Of course, this is true to the limit of overtraining.
So it seems very logical that squats and deadlifts, being particularly stressful on account of the amount of muscle being recruited, the poundages involved and total effort, do create a particularly effective anabolic response. They are also very easy to overtrain on.
Any studies on this?
It would seem that a training regimen based on total stress level would be interesting to look into. Of course, HIT does seem to have some of these ideas in it, but in a less formal way than what I envision here.
