  • After you have mastered a zone of apposition (ZOA) during exhalation, you must be able to maintain it. Dr. Sarah Petrich reviews the ZOA and the diaphragm biomechanics during the breathing cycle. She then demonstrates three exercises that train the ZOA and strengthen one’s ability to acquire and maintain the ZOA with the coordination of the abdominal muscles.

    The adduction drop test and apical expansion tests were used with permission from the Postural Restoration Institute®.
