The subject pretty much says it all. I've been working out for a little over a year. I am currently doing a Waterbury workout routine. I try to always stay in proper form, and I never consciously use one arm more than the other.. .
However, there is a very noticible difference in size between my two traps/shoulders. (one droops down from my neck while the other one makes almost straight line.) my friends always point it out to me as it's getting annoying.
PS: I measured my two arms, and one is longer than the other. ,...would this have an effect at all?
