Utthita Parsvakonasana
Extended Lateral Angle

• Begin by stepping your feet apart so when you extend your arms, your wrist are directly above your feet.
• Turn your right foot out 90 degrees and turn your left foot in about 15 degrees. Your right heels should bisect the arch in your left foot. 
• Hug the muscles of your legs 3 dimensionally around the bones and isometrically squeeze your legs together.  Note: Isometrically means to scissor your legs together and engage the inner thigh without moving your legs.  This will help give you a stronger foundation for your posture.
• Draw the arches of your feet up and extend through the crown of your head.
• Inhale raise your arms to be parallel to the ground.
• Exhale, bend the right leg so the knee is directly over the right foot and the thigh comes parallel to the ground.
• Place the right elbow on top of the right leg and the left arms extends rights past the left ear.
• Pause and feel the stretch from the left leg up to the left finger tips while keeping the left shoulder blade flat on the back.  Then place the right arm behind the right leg on the ground.  (Note: If this is challenging, see modification image below with block).
• Draw the head of the left leg bone back as you tuck the tailbone forward.
• Turn your head to look up at the inside of your left arm and continue to revolve the torso up towards the sky revolving from your armpit, not the tips of your fingers.
• To release: Exhale bring both arms parallel to the ground as you straighten your upper body.  Then straighten the front leg by pressing down into the foot.  Continue on the other side to balance out.
