Stand with your feet together. Bend your knees, extend your arms overhead, and lift your gaze to the thumbs. Drop your tail and scoop the belly up and in to support your back. Ground into your heels as you sit your hips and use the inhales to reach up out of your pelvis by lengthening the torso. Feel the opposing actions of the posture as you breathe fully into the upper chest.
To refine the posture, roll your triceps in with an external rotation of the arms and press your palms together to engage the chest and sides. Alternatively, for those with very tight shoulders, keep the hands shoulder-width apart or even open the arms to a Y-shape to help relax the shoulders down while maintaining the upward energetic expression of the pose. Stay for 5-10 breaths as you continue to find your way into a deeper sit and a higher reach.
