Bring a little “Centering Mountain Pose” into your commute and make the most of standing around.  From our “12 Yoga Poses for Your Workday” gallery:

“Sit or stand tall. Feel lift through the center of your body, from the base of your hips through the crown of your head. Close your eyes and let go of the sights and sounds around you. Deepen your breath and
watch the flow of your inhale and exhale. Feel the quiet centering and
balance that comes into your mind as your inhales and exhales become
resonant and even.”
