From Intense Side Stretch, plant the palms on either side of the right foot.
Kick the right leg behind you, coming into Three-Legged Dog.
Take a breath in, and as you exhale, slowly lower the right foot toward the floor beside your left foot, but before it touches the ground, swing it back up to the right, making a circle and coming back to Three-Legged Dog.
Repeat, circling the leg for a few breaths in this direction, and then reverse the direction of your circles for another few breaths.
