I experienced acute lower back pain after walking for 30+ minutes. I searched the whole internet to find a solution but only found advice saying, "if you have back pain, walk!" which was ironic since my pain occurred while walking. Then it dawned on me: I sit most of the day, cycle a lot, and drive my car, but I wasn't walking regularly. Now, I walk the dog for 40 minutes a few days a week, and the pain has disappeared!
