Make sure both of your feet are pointing forward. Inhale lifting your arms straight up, like in a Warrior One position. Keep a gentle bend in both of your knees but make sure you don't bend your front knee past your ankle, this is a general rule of thumb to remember in yoga. Twist your hands internally so you open up your shoulders and relax your neck. Meddy Teddy loves this position and has a lot of fun doing it. Take a look at this picture of Meddy Teddy practicing Crescent Lung Pose to give you an idea of how it should look.
