(Beginning your practice with this pose will prepare the muscles of the arms, shoulders, and chest.) Stand on your mat with your feet hip-width apart and your leg muscles strong and engaged, toes spread and lifted. Interlace your fingers behind you, inhale, and lift the sides of your chest so your shoulders are level with the base of your neck. Move the tops of your shoulders backward with your chin slightly lifted, and imagine your shoulder blades connecting to the back of your heart. Exhale; lengthen your arms away from your body and shine out through your heart, feeling a fullness inside. Hold for 3 to 5 breaths.
