Qi Qong (Chinese Yoga) is possibly the oldest form of healing in TCM along with Herbal Medicine. Thousands of years ago villagers used to perform a dance or series of movements, some were fast and flowing and designed to strengthen, some were slow and deliberate designed to improve stamina, breathing and health, many of these became what we would call modern day martial arts such as Tai Ji (or Tai Chi) These movements were developed through time to improve and preserve health through breathing, movement, meditation and dedication.
There are many, even tens of thousands of styles of Qi-Gong, some are as old as the families that have passed them down through the generations. Some are more modern and some are born totally from a western perspective and teaching, from western people trying to copy an ancient Eastern art.
Regardless of when or where it came, Qi-Gong is an exercise that is designed to calm the mind, improve breathing and peace of mind and in many styles keep the body subtle, fit and healthy. The beauty of Qi-Gong is anyone can do it, regardless of age or physical ability, you don't have to be a boney, bendy Yogi to benefit from these gentle flowing exercises.
