Do I have to lift really heavy weight on that side? Unlike most muscles, uneven traps are easier to spot so does anyone know another way to fix it?
I'm right handed, had this problem for about a year or two.
I remember as a kid I would always lean on the right when writing in school as in my head on shoulder, while it was flexed. My trap started hurting, any I never knew why(I was like a 11) I stopped doing that but it's not back to its original size.
