Classes begin with light calisthenics and stretching, followed by technique-based drilling.  After the warm-up, the instructor will teach 2-3 specific and usually inter-related techniques.   Students will perform drills and other exercises designed to help them retain the technique.  After drills, students will spar (or roll), putting their techniques to the test with training partners who can resist and counter just as they would in an actual fight, providing valuable real-world experience should the techniques ever need to be applied in an actual fight.
