Qigong and Chi Kung both have the same meaning, and are often translated as breathe or energy work. It has its origins in Traditional Chinese Medicine, and is designed to stimulate the flow of chi (energy) through the internal meridians, and is a method for self healing.
It has similar principles to Tai Chi, and sometimes it is hard to separate the two as both practices come from the same seed. The main noticeable difference is that in Tai Chi there is movement from the feet, whereas generally qigong has more specific standing, stretching and breathing exercises, as well as visualisation techniques. The techniques can be learnt by any individual regardless of previous experience or background.
The beneficial effects of practicing qigong are numerous, including improved flexibility, becoming more relaxed and having a more positive outlook, as well as helping to manage some more serious illnesses or conditions.
Once learned some routines and exercises can be incorporated into daily life to help maintain and restore the body for a happier and healthier life.
