From Warrior 2, straighten the right leg, and turn the toes so both heels are pointing in (photo above shows the front view of the pose).
Bend your knees coming into a wide squat until your thighs are parallel with the ground. Your knees should be directly over your ankles, so adjust your feet if you need to.
Lift your arms up, bending your elbows so they are at 90-degree angles, opening the palms away from you.
