My arms kinda suck as my shoulders overpower in size as compare to my arms and make my arms look small they are about 16 inch when i flex(about 15.5 without flex). im starving for more boost in my arms, my triceps r alrite but look like biceps have never peeked out(little peak. i just want them to look good.

And for biceps i do them after back and i do these
pullups
Barbell curls
hammer curls
incline dumbell curls

Is there any way to get my arms more proportionate? I think I just got screwed over on genetics...maybe...i odnt know
any comments or critique
love to hear
