I tried a few exercises over time and I also lift semi-regularly. I'm in pretty good shape so my lower back should be able to support me, but at times, even when I think I'm walking straight, I'm walking hunched (it's like my neck is naturally forward). I deadass need to stick my chest out and look like a tryhard just to even out the hunched back. I might try checking with a doctor, but I'd like that as a last resort. For context, I've worked on walking confidently, and looking up, so that shouldn't be the issue.
