Presently experiencing some lower back pain? Try not to talk while you walk to help keep the strain off your lower back. In order to talk you need to breath more often to produce sound which distracts deep trunk muscles of the spine. These muscles support the spine while you are maintaining an upright posture. Therefore, you leave your lower back unsupported and vulnerable to discomfort. It is subtle; however, if you are uncomfortable it may just make getting around a bit easier on your body.
