So lately I have been focusing on my back more. I have always loved doing back, but I never had big traps and no matter how hard a worked my upper back it never seemed to get thicker. Then I noticed the rhomboids, and focused more on rows and my form on those. And then I noticed on a couple of pictures of Evan or Frank on the internet, or any other big body builders, that it seems their traps and rhomboids connect and morph into each other? So my question is, do I just need to work my rhomb's and trap's more and keep waiting for them to grow into place? or am I missing something? or is it just genetics that I dont have big traps? I have decent lats, just need help on upper back.
