From the Fish Modification, sit up, bend the knees, and sit on the heels with the thighs together. If this causes pain, place a block or a large, rolled-up towel between the heels, and sit on that.
Bend your left elbow behind your back. Lift your right arm straight up above your head. Bend your right elbow, and if you can, clasp your hands together. If your fingers aren't touching, hold a strap or small towel with both hands to encourage your hands to move closer together.
Keep the spine straight, pulling the ribs and tailbone in. Gaze forward for five breaths.
Release the arms, and switch sides so the left elbow is on top, holding for another five.
