Unless you know for a fact that you have disc/structural issues, a lot of lower back pain stems from a combination of tightness and weakness through the hamstrings, glutes, hip flexors, and abdominals (among others). I dealt with low back pain off and on for years, but started doing yoga about 8 years ago. It's not a quick fix, and if your dealing with tight/weak muscles, there is no legitimate quick fix, but over time it will work wonders. It's made a massive difference in my life, and I highly recommended it to everyone I know.
