We do 5-10 minutes of stretching plus basic punches and kicks to start, then move on to the "workout" portion of class. That varies each day (or week, if we are doing a theme for the week) and can be partner drills, focus on details of techniques, sparring techniques, or kicking drills. This week, for example, each class focused on their board breaking techniques, except for white belts, who did running drills and partner drills. Adult class did one day of detail (my favorite), and one day of sparring techniques. After 20ish minutes of that, we do a water break then the rest of the time is spent on curriculum. Whatever each student needs to work on, basically.
