I don’t know about the lower back specifically, but I know that hiking/ walking long distances is medicine for your knees. And running is medicine for your whole circulatory system and spine. If I don’t exercise, I begin to feel the difference within a couple weeks. But if your knees start to hurt- you need to walk. Standing is no good. It’s walking that helps, and especially walking up and down mountains. Your knees might be sore the first couple times you do this but after a while they will respond to the stimulation and become much tougher.
