I recently restarted my gym lifestyle and as expected DOMS made their appearance, specially chest shoulder area, now my issue is not how to deal with them on a daily basis but specifically when I require those muscles to do another exercise in my case, squats; I've been trying to stretch my shoulders all day trying to reach a similar position as if I was holding the bar behind my neck(like for squatting) but the discomfort is really bad.
I was wondering how can I deal with DOMs while working out, stretching, avoid movements that cause aching, or just suck it up and do the routine.
