I had three different therapies for my back (exercise machines, acupuncture and something that hammered the muscles so they would relax, does not hurt as much as it sounds but it hurts) they all lasted for a few month. Two Years ago I started going to work by bike (7km). Doing that every workday has kept the back problems away ever since. I just hope I can keep that up the rest of my (work-)life. Though a shower at work would be nice. Not so much for me but my colleagues :-) I can still hear podcasts while biking so I don't "loose" the time. Public transportation would take the same amount of time and is more expensive.
