After opening the back in Camel Pose, while standing on the knees, arch the back and lower the hands behind you. If it's too difficult to do this way, lie on the back with the knees bent and arch the back from a Reclined Hero Pose position.
Rest the head and forearms on the floor and try to touch the toes with your fingers. Go deeper if you can and hold onto the heels.
Hold here for five breaths, breathing as deeply as you can.
