I know some people have a problem with one arm being too big but just picture one huge side of my neck , and nothing on the other, it looks absolutely rediculous. In my job (farming) i have to use controls that are about a foot above my head so my traps on my right are too big. Using my left hand is not an option. how can i even them out.

I've been trying upright rows but i only ever seem to feel it in my right side, i think my right does all the work.
