I’ve been working out for about three months now and just realized from looking in the mirror that I have developed a bulge next to my left shoulder blade when I stand with my shoulders back. It’s completely painless which is why I didn’t notice it until I saw it in the mirror. I have one on the other side too, but it isn’t as profound. I think it’s a muscle I’ve been unknowingly developing over the past three months from doing an exercise wrong because my mind to muscle connection is poor. Looking for advice on what I’m doing wrong and tips on developing mind muscle connection. Also confirmation that it’s actually a muscle and nothing to worry about.
Can upload pics if needed.
