Unfortunately, it goes both ways. I started training 6-7 years ago and today have constant lower back pain (non-existent prior) and chronic shoulder pain (again, non-existent prior). When you lift, even with reasonable weight in a conservative progressive overload program, injuries can and will occur. In my case, there was no singular “injury”; the pain just gradually crept in and has not gone away.

I still wouldn’t stop weight training, as it’s a part of my life that I love. However, despite never going for ambitious PRs, I have chronic pain that I never had prior to starting - and no amount of physical therapy has resolved it.

As always, YMMV.
