Posture: Stand with your legs spread as wide apart as you comfortably can. Place your hands on your hips, positioning your fingers behind you and your thumbs in front.
Exercise: As you inhale, arch your back by bending backward at the waist as far as you can manage. Hold this position momentarily. Then, as you exhale steadily, bend forward to lower your head toward the ground. Repeat this sequence five times to start.
