From Pigeon, swing your left leg forward. Sit up nice and tall, drawing the right sole of your foot against your inner thigh.
Lengthening through the spine and keeping your left leg straight, fold your torso over your left leg. Rest your hands on the floor on either side of your leg or on your shin for the full expression of Head to Knee A.
Rest here for (at least) five breaths, being sure to continue lengthening the spine as you relax the shoulders away from your ears. Then slowly sit up and switch sides.
