Hapkido energy breathing, which is commonly known as Danjun breathing or Tanjun breathing (there are variant spellings) is typically an important part of the art. It involves drawing the breath slowly and fully into the danjun, which is the center of ki located in the lower part of the abdomen, and releasing it.
The breath is thought of as ki or life energy. Danjun breathing teaches one to focus energy.
Danjun breathing can be done softly, with relaxed movements, or strongly, with the muscles tense and energized. In my own class we do it softly. We do this at the beginning of every class.
