Circuit training is a type of exercise routine that keeps you moving almost constantly for the entire workout. You'll move from one activity (or station) to another in quick succession, each set of exercises working a different muscle group for a complete, full-body workout. You'll do each station's exercises for about 30 seconds to three minutes, and then move on to the next station until the workout is complete. How many calories you burn doing circuit training (including boot camp workouts) depends on your speed, weight and gender.
