To successfully perform circuit training, a series of different exercises is done in succession. Circuit training is popular because an increased amount of calories is burned over other forms of training with greater results than conventional training in a reduced amount of time. According to the National Academy of Sports Medicine (NASM), using a circuit training program will “incorporate both cardio respiratory and resistance training into one’s routine, enhancing caloric expenditure.” The bottom line is that this type of training will help you lose weight faster than conventional cardio.
