Customs and Immigration Downward Dog
While waiting in line at customs and immigration, or while hanging out waiting for your luggage, this slightly inverted posture will clear your mind, stretch and extend your spine, and open up the backs of the legs (hamstrings and calves) as well.
TO DO: Find a ledge or even a wall and place your hands on it. Walk your feet back and tilt your body down towards the floor (allowing there to be a right angle between your legs and your torso). Breathe and enjoy. Namaste!
