Stand with your feet together and legs straight (Mountain pose). Pressing thighs, knees and ankles together, bend your knees as if to sit. Inhale and extend your arms up and overhead, forearms parallel. Draw your shoulder blades down and back, keeping your breastbone lifted, spine long and abs firm to maintain a strong, erect torso. Hold for 3 to 5 breaths, sitting a little deeper and extending arms a little higher.
