Qigong and Chi Kung mean the same, often being translated as breath or energy (Qi/Chi) practice or work (Gong/Kung). Practitioners will often say that "qigong is thousands of years old." Whilst it is true that some of these exercises have developed over great periods of time their roots being traceable in cave paintings from times B.C, the first recorded modern useage of the term Qigong in this context appears in a medical paper written in China in the late 1950's.
As both Qigong and Chi Kung can have various meanings, a more accurate definition should perhaps be "Energy, Information and Skills, acquired through Practice over a period of time". There are numerous different kinds of Qigong, ranging from gentle to ferocious, medical to martial, lightweight to hardcore and (frankly) brilliant to bonkers.
I hope this site will help you find one that suits you...........
