Inhale, and as you exhale, engage your abdominals, hold your ribs in and create space in your side as you lean your torso to the left. Reach your arm up and over to stretch the sides of your waist. Inhale as you return to the starting position, and exhale to complete the movement. Place your right hand on the mat, extend your left arm straight up and lean to the right.
