Ok, simple question for you guys.. I have HORRIBLE posture and it's getting annoying constantly having stiff neck and shit.. what would be the best exercises you guys would recommend for fixing horrible upper back posture? As in, I round my shoulders forward and jut my chin forward without even realizing it until I'm like "Ow.. why am I hurting? Oh yeah. Duh" Shrugs? Single Arm Rows? Bent-Over BB Rows? Open to anything, really..
