Many mistakenly believe that Tae Kwon Do focuses on the breaking of boards and bricks and therefore, is not safe or healthy. The breaking of bricks and boards is but a small part of Tae Kwon Do, and it is done only to demonstrate power and focus of a specific technique. Tae Kwon Do is a comprehensive discipline that utilizes all the muscles of the body. Because of this, it is a natural weight regulator, taking pounds off where appropriate, putting them on, or redistributing them as required.
