Yes, this is a yoga pose. It requires core engagement to extend your arms straight up, sturdiness in the legs to anchor you down, and external rotation in the shoulders to keep it all together. It also requires a bit determination to sustain. Serena does it perfectly.
When we do this pose in yoga, we might hold a block above our head. But often, it's just our hands, palms facing one another, holding nothing like the well-earned trophy here.
But what if we did this pose with the vision in our mind of holding something triumphant above us? What would that be? What would inspire you to reach, uplifted, fully triumphant?
