Step-by-Step TechniqueGet comfortable: Lie on your back on a flat surface with your knees bent, or sit upright in a supportive chair with your shoulders relaxed. Position your hands: Place one hand on your upper chest and the other hand on your stomach just below your rib cage. Inhale slowly: Breathe in quietly and deeply through your nose for about 2 to 4 seconds, feeling your stomach push your lower hand outward while your chest stays as still as possible. Exhale gently: Purse your lips (as if blowing through a straw or blowing out birthday candles) and exhale slowly through your mouth for 4 to 6 seconds, feeling your stomach move inward.
