I too have a 'bad back' (oh, for a more specific diagnosis than that!) and I find that walking is very good for it. I have a lot of stiffness in my back and nuerological symptoms like numbness and pins and needles. Thankfully, not so much pain and so it seldom stops me doing things. I have found, like others on here, that moving - especially walking - really helps with my particular problem. Also, I have found that physiotherapy and specific strengthening exercises work for me. The trouble is, I think, while many of us can commiserate with each other it is very difficult to offer advice because - as Jon said - there are so many causes of back pain and the best course of action will vary depending on exactly what the problem is. I think that I unjured my back falling asleep on my friend's sofa about 7 years ago. I know this sounds a tad ridiculous but I think it's true. I am finally getting close to a proper diagnosis after all these years and - to be fair to the NHS - the main reason it has taken so long is because I did not push for answers. I went to the doctors when I first had the initial injury and it cleared up (well, OK, it never cleared up but I got to the stage where I could work and exercise and didn't need painkillers very often so I decided I didn't need to go back to the doctors). I decided ages ago that I just had a bad back like so many others and that, whatever the cause was, it didn't stop me doing things so I should just be grateful and get on with things. Consequently, I have put up with pain, stiffnes, numbness, and pins and needles for 7 years. A physio that I started seeing for another problem eventually managed to nag/frighten me into trying to get some proper answers. So, I went to my GP about 2 years ago and am finally getting some answers. So, the point of all this waffle is that my advice is do not ignore a problem like this - push for it to be investigated and don't give up until you get an answer. It may be that I have something that I just have to live with (I can do that, been doing it for years) but it is also possible that I have something that can be treated and I regret not pushing harder for answers years ago.
