Be barefoot. Stand in Tadasana. Step your feet about four feet apart. Stretch your arms out the sides, shoulder height, palms facing the floor. Throughout the posture, keep strength in your arms and legs, rotate your pelvis back, and lengthen your spine. Turn your left foot in 45 degrees by pivoting on the heel. Turn your right foot out 90 degrees, also by pivoting on the heel. Swing your hips to the left as you stretch out to the right. Place your right hand on your right leg and extend your left arm straight up toward the ceiling. Do not allow the bottom arm to support any weight. Let your legs support you. Extend evenly on both sides of your body. Do not compress the lower ribs and hyper-extend the upper ribs. Look straight ahead or up at your left hand. Soften your gaze; quiet your hearing; relax your jaw. Breathe evenly and comfortably through your nose. Come out of the pose by unbending at the right groin, keeping your spine straight and long. Repeat to the left side.
