Many people who see chi exercise machines without trying them feel these devices are not actually giving any real form of exercise. The body is moving, but how could that motion be considered exercise when the user is making no effort and looks totally relaxed?

What's a Chi Machine®?

The term “chi machine” is used generically for a type of passive exerciser that gives a valuable form of exercise to the human body while the user is lying down.
