1. Place one hand on the chest near the diaphragm to control the lower or inferior lobes. Deeply inhale and exhale until the hand moves in time with the breathing, showing that air is entering the lowest region of the lungs.
2. Place the hands on the outside of the lower rib cage and transport the air to the outer section of the lower lungs after three to six rounds of this sort of breathing. Rep three to six times more in this hand posture, focusing your concentration on the lungs behind your hands.
3. Wrap the hands over the back of the neck, fingers pointing towards the spine, and take three to six deep breaths into the rear region of the lower lobes.
