For the past several years I had serious problems with lower back pain, once every few months it would get so bad I couldn't stand/sit/walk without severe pain for at least a week, even painkillers didn't help much. One year ago I started to exercise at gym, twice a week, and it worked wonders - no back pain, except for minor one from time to time if I lift something the wrong way, but overall I feel so, so, so much better (and look too xD).
