SERGEI Krivov has a way with body movements that might lead you to believe that he is an eighth dan in karate. In reality, however, Krikov is an exponent of eco-yoga, the central theme of which is to listen to ones own body. Says the 30-year-old Russian: "When you stretch your body, you are following instructions which your body proposes. The main thing is to achieve harmony with your astral body environment." The eco-yoga practitioner has evolved a series of exercises that increases energy levels and keeps one in sync with the bodys requirements. One of these is non-breathing therapy.
