Yoga Poses to do at Work

I sit at a desk from May until Mid October.  My hours are typically from 7 to 7. Although I am still sitting in lotus or double pigeon and that works wonders on my hips, I can't help but feel a slight ache in my spine and shoulders if I don't take a moment to stretch, walk, or breathe deeply. 

While writing this blog entry I am literally doing the following poses.  Not only do I feel more awake and attentive, but my breathing has become deep and full and my posture more erect.  How do you feel after doing them? :)

Have a wonderful day at work yogis!
