Caterpillar the Chest Reflex Region
Let the left hand support the foot again, as the right hand will start the sequence. Using the right thumb, you are going to thumb walk the chest region in an inchworm, or caterpillar, type movement.
Beginning at the heart reflex, thumb walk up from the heart reflex to under the great toe, turn, and thumb walk down to the diaphragm line. Continue to thumb walk in this manner up to the base of the toes and down to the diaphragm line in a curvy line until the thumb reaches the outside edge of the foot. The left hand is holding the foot, gently clasping the toes, as the right thumb walks across the reflexes. The fingers of your right hand may rest on the top surface of the foot while the thumb does the work.
Do not overstretch your hand. If you feel the thumb is pulling away from the fingers, curl the fingers up behind the thumb; the fingers come along for the ride as the thumb works across the ball of the foot. There will be many times throughout a session where you will need to adapt your reach. Always pay attention to your form; if you feel your fingers stretching away from one another, readjust.
This caterpillar technique is the preliminary walk-through for all the reflexes on the ball of the foot. Each little bite is working on reflexes that deal with the lungs, windpipe, bronchi, bronchioles, breasts, upper lymphatic, thymus, or the heart. Each foot contains the same reflexes.
Once the right thumb has created the curvy path from the inside edge to the outer edge, switch hands. Now the right hand is the supporting hand and the left hand is the one doing the work. Use the left thumb to caterpillar back across the ball of the foot. Take small bites, turning down into the curves each time and walking up again. This movement will bring you back to the heart reflex again.
