Pigeon Indeed

Yoga's getting harder, although I still feel great afterwards and I think my body's getting stronger. The new intrigue of last night's class was a pose called The Pigeon. Visualize, please:

Kneel and point your toes behind you. Fully rest on your extended feet. Now take one leg and extend it all the way back, pointing the toe, resting it on the mat. Straighten your spine so that the crown of your head faces the ceiling. Now raise your chest, puffing it out as far as it can go. Stretch out your neck too. When you've thoroughly felt the pull everywhere in your body, slowly take the foot that's bent underneath you and bring it toward the middle of the mat so you're sitting on your hip. Continue to have your other leg fully extended, and face your torso forward with your spine straight. Now extend your chest and neck again.

Once you've eased out of that pose and come to a relaxed position for a minute, don't become too complacent. You've still got to repeat all of that, but switching legs. Who's the pigeon?
