Martin Christensen
Martin Christensen Sensei holds the rank of Godan, fifth degree black belt, and has been teaching Aikido in the Fremont area since 1994. He brings to the mat 56 years of Aikido experience as well as a keen interest in Qigong, Reiki, and Tai Chi. Martin Sensei emphasizes a strong foundation in kihon waza (basic Aikido forms) and the practical application of these forms to "real life" situations. He is very interested in helping students understand how to better “feel” and “control” ‘Ki’ (vital life force) and utilize this ‘energy’ in their daily lives. Martin Sensei believes that an ever deepening understanding of the healing aspects of ‘Ki’ brings an improved understanding and utilization of martial energies.
