For me the solution ended up being very simple, going for walks.

This wasn’t easy at first because shortly in I’d have back pain just from walking, but over time this subsided and I was able to walk longer.

Now I go for a walk over lunch and use it to think about my work (which is great for brainstorming). Any time I stop my regular walking routine my back pain starts to creep back in so I know the walking has helped a lot.
