Hello all, I'm a daily lurker, but never really post anything.

Anyways I've noticed that I lack symmetry in my arms. My right arm dwarfs my left arm in size. I've been doing more and more exercises with Dumbells to avoid having one arm do the work for the other, but this is seemingly having no effect. What is actually happening is my right arm is getting bigger, while lefty is getting left behind.

There does exist a slight strength difference between the two, most apparent on exercises such as bicep curls, and d.b presses.

Any tips you can give me on evening them out? i didn't know if it was advised to use a heavier weight for d.b bicep curls on one side or the other.

The picture doesn't really show the dramatic difference, but believe me, its' there.
