In early 1990’s during his post-doctoral position at Harvard Medical School, Dr Kichul Cha, Discovered the results of bio-electrical impedance analysis (BIA) were Fundamentally inaccurate. He pointed out how different body parts have different levels of impedance, to accurately analyze body composition, the body will need to be analyzed by segments instead of as a whole.

Dr. Cha developed the methods that would overcome the limitations of BIA and transform how BIA would be measured. With this he created the InBody.

In 1996, Dr. Cha founded InBody Co., LTD. in Seoul, Korea to produce and promote the InBody and its revolutionary methods. The InBody features direct segmental multi Frequency bio-electrical impedance Analysis and uses an eight-point tactile electrode method, which can precisely measure individual body compositions.
