chi machine, HTEAmericas, classified as Class 1 medical device, FDA approved, exerciser, As seen on The Doctors, ankle cradle, Dr. Inoue

To understand the Chi Machine, one must first understand the word "Chi". "Chi" is a Chinese word referring to the life force or life energy that is said to flow in channels through all living forms.

The machine is a box-like device with an "ankle cradle" that moves from side to side. It is claimed to oxygenate the body via passive aerobic exercise meaning that the body is experiencing non-impact aerobic exercise. A simple analogy is, if you walked very briskly for 30 minutes, you would oxygenate your blood as much as if you were on the Chi machine for only 5 minutes. "Chiing" for 15 minutes is as aerobic as walking quickly for one and one half hours. How's that for a time saver?

The original Chi Machine was created by Dr. Shizuo Inoue, Chairman of Japan's Oxygen Health Association, who has over 38 years of experience. Dr. Inoue's design was based on human physiology allowing the body to work effortlessly with its own natural frequencies and movement.

Dr. Inoue spent 38 years of his life researching the effects of oxygen on the body and the Chi Machine is the end result of that medical and kinematic research. The Sun Anchon Chi Machine is the original Chi machine and is the only machine available on the market that is classified as a Type 1 medical device by the FDA.
