I don't remember where I read about this but supposedly studies have shown that when only one side/limb of the body is trained, the other side will receive (although less) a certain amount of stimulation for growth as well. In other words, the body does not allow one side to become overly dominant.
The reason I'm bringing this up is because I tore my left triceps a week ago doing seated dumbbell extensions. It hurt pretty bad and several days later I had some bruising under my arm. The pain has subsided and they are no longer sore to the touch, but I would think the earliest I could train them again would still be several weeks away (I tore my calf from a ski accident once and it took several months to fully heal).
I have skipped the last two triceps workouts due to the injury and now I'm wondering if training my good arm the entire time will cause the left to grow a bit(in this case heal a bit faster).
Any thoughts about this or has anyone heard about one-sided training?
