I dunno I am not going to tell you what to do but me personally I dont think its extremely attractive when u see those muscular women on television flexin on stage n stuff... Im not quite clear yet if that is the look your going for but I would advise against it.. sounds like your already pretty knowledgeable when it comes to working out, and u got the basics down, why not just try to refine your diet, try something new at gym, etc?
Really the only type of guys you see with those chicks are the massive 270 lb meatheads... but if thats what ur goal is U GO GIRL

(no offense to all 270 lb meatheads in here I know ya'll need love too lol jk)
