Remove the props and lie down on your right side with extended legs—as if doing a side-lying Mountain Pose. Keep your feet flexed and your top arm out in front of your chest with your fingers on the floor for stability. Prop your head in your right hand. Reach your right elbow farther from your torso to extend your bottom waist and rib cage. Stay for 1–3 minutes, then repeat on the other side. This opens the side of your body that is on the mat. Breathing easily depends significantly on finding space and freedom of movement in this part of the body.
