Walking is a good way to keep your lower back healthy. If you are suffering from an SI joint dysfunction, you are advised to start slowly, let’s say 20 minutes, 2 times a week. While walking, make sure you use comfortable footwear. The low-heeled version shoes are better. If you do not feel any pain with this walking frequency, you can add more time to your walking session or you can speed up the pace. You can go up to 30 minutes per day.
