From Trikonasana with your right leg forward, bend your front knee. Place your right hand a foot forward to the little toe side of your right foot, on a brick, or the ground, left hand on your hip. Step your left foot forward a little, press down through the three points of your right foot.
Inhale, float your left leg up to hip height or slightly above, toes facing forward. Flex your foot parallel to the ground, press out through the heel.
Hips and shoulders stacked, reach your left arm up high, palm facing left, gaze down or to your left fingertips.
