Short of joining a gym or getting too into your workout i would suggest some squats and lunges every day or so, even with just body weight. This will help build up the stabilizer muscles fairly well. It's not something that can be fixed with just walking alone. I have had lower back pain often over the years and every time i get it its almost always come at times where i am not going to they gym regularly, where i do those movements often.

just some preventative measures anyway.
