Pull-ups were the key for my back. Once I could complete a set of 10 with body weight only it was like magic. Though, I do think that the pull-ups forced me to strengthen my core, which had a major impact. Then once those muscles were able to keep up it made everything else easier too.

I wish moving to a different instance was easier, I don’t want to put in much effort and it doesn’t appear to be super easy
