(also spelled Qigong, chi gong and chi gung) Romanized Chinese “qigong” sounds like [ch’i kung] or chee in the English spelling system, and not like [ki gong]. or key. To understand the definition of Chi Kung  one must first understand the definition of Chi. Chi or ki (pronounced like "chee") can be defined in many terms like  Prana, Aether, Life Force Energy, etc. For easy understanding it is  "the circulating life energy that is inherent in all things". Kung (or Kung Fu) is defined as "learned skill", or "hard work". So Chi Kung means a multiple of terms like "energy cultivation",  or "energy work" and practicing with the breath, etc.     Chi Kung benefits' Energy - Stamina - Well-Being   Health - Vitality - Wisdom Serenity - Peace - Relaxation Chi Kung specifically addresses issues of health and well-being by building the internal strength of your body, mind and spirit.
