CNSDS
Charles Nelson studied the fighting habits of street fighters and muggers, and in response developed self-defense techniques based on Mongolian Wrestling; there are no wasted movements, just real street techniques perfected by Charles Nelson. In 1997, after 50 years of teaching in New York City, Mr. Nelson retired and authorized 6th-Degree Black Belt and senior student Robert Spiegel to teach his system. Robert Spiegel personally conducts and supervises all training. The Charles Nelson Self-Defense System course will teach you a small number of easy-to-learn principles and techniques that can carry you through just about any violent conflict.
