[Meerschaum]

I was wondering this, I know muscles grow in response to stimulis individually, and yet they all feed from the same collective system, certain muscles grow faster than others (legs for example), and can rebound faster if allowed to slip, is it possible to try to use this to your advantage in say PCT, cause selective degeneration by not working say legs? would the body focus on catabolising the areas that are left un-worked? or also while cutting is it possible to make gains if the muscle group trained is very small and thus your calorie intake is more apt to be enough to cause hypertrophy?, or if someone just say simply focused all their efforts on upper body, would they progress faster than if they had added in squats?... I know asymmetric growth might be ugly and counter productive long term, but I'm just curious what you guys think.
