Walking can improve your overall health and has many benefits to your spine. Walking can strengthen your back muscles which helps to keep your body standing upright and improves your posture. Exercise walking even helps to prevent osteoporosis and back pain. It’s important to try and walk every day for at least 20 minutes. While walking can cause pain for some back issues, you can try walking around in a pool because the water buoyancy will help to alleviate the pressure on your back.
