To control and overcome greater size, strength, and aggression with lesser size and strength is the keynote of the sport. This is done by utilizing superior leverage, grip, and position upon your opponent. Students of the sport gain a deep understanding of the workings and limits of the human body.
This knowledge can be used to subdue and control an opponent with whatever level of severity the student chooses. The path to this knowledge is physically and mentally demanding. Students benefit from greatly increased physical fitness, problem-solving ability, self-knowledge of their body and mind and the many social benefits of working within a large group of like-minded fellow students as you learn and have fun together.
