I have back issue (possibly an injury, but will need a MRI to confirm as nothing shows on CT) - I find that the issue is helped by climbing, and light weight-lifting involving the back-and-shoulders - just lifting dumbbells with arms outstretched, enough weight to offer resistance that engages the muscles properly. I find the "puzzle"(or crux) in the climb make it less boring then repetitive movements at a gym, plus the genuine sense of fear from the danger helps me push my limit a bit (though I did have a poor fall as a result, so needs some caution). Also, practical if you like to work with your hands, and I think for guys having decent arms and shoulders are particularly attractive.
