The clientele for Grandmaster Hausel's martial arts classes are adults. Adult martial arts and karate classes can focus on fast and powerful techniques. But Grandmaster Hausel often has adult students that have limitations, so he takes these into account in order to keep everyone safe. The reason for focusing on adult classes is because Grandmaster Hausel has taught nearly his entire life at universities - to university students, faculty and staff. He has very limited experience with kids. In addition, most traditional Okinawan martial arts restrict teaching to members who are 16 and older.
But because of the dangers in society, Soke Hausel has opened his classes to families - in other words, mentally mature children (10 and above) can train with their parents in his classes. But these kids must always be accompanied by their parent(s).
