The lower back can experience strain, stress and pain if other structures in the body are not working correctly. For example, when you walk the feet/ankles, hips and trunk all need to move effectively to help swing the arms and legs and transfer weight from side to side.  If these areas of the body are not mobile enough, then the lower back tends to move too much to compensate and it ends up experiencing pain and fatigue.  This short video blog from Justin Price (creator of The BioMechanics Method) shows you two easy exercises you can do to help other areas of your body move better so that your lower back can relax and feel a lot better.
