2. Keeping both feet flexed, stack your left foot on top of the right with your legs very straight.
3. Bring your left arm up towards the ceiling and your gaze to the left fingertips, coming into Side Plank.
After 3-5 breaths, roll back to the center and do the other side, resting in Downward Facing Dog between the two sides if you like.

Challenge Variation: Lift your left foot, hovering it above the right. If you still need more, try full Vasisthasana.
