Free sparring is permitted only after a certain degree of skill in Shotokan fighting techniques has been accomplished. The reasons for taking Shotokan truly vary from student to student. Some are fascinated by Japanese culture, and there is a lot of Japanese language and cultural matters stressed in the class. Others know it is one of the best workouts on the planet, and want to learn something challenging and useful while they're working out. Still others are amazed by its beauty and grace, and some are looking for an excellent way to come down from a long day of classes or office work.
Shotokan classes are open to anyone, and NO ONE is too old, too fat, too thin, etc.
