Chinese Martial Arts are sometimes divided into two adversarial camps: Internal vs External. This has always bothered me as it is usually in some kind of advertising where I see these terms. Over the years as I have kept abreast of anatomy, neuroscience research and related disciplines as part of ongoing professional development, I have always looked to resolve what I percsive a false distinction. In 2010, I published a draft definition of internal practice in my FAQ. Since then I have been fortunate to receive feedback and continue to refine the definition.
