circuit training is a type of interval training in which strength exercises are combined with endurance/aerobic exercises, thus giving you all the benefits of both a cardiovascular and strength training workout. The term circuit means that a number of carefully selected stations will be positioned around the facility consecutively, which may range from hydraulic equipment, free weights, resistance training, squat thrusts, pushups, star jumps, sit-ups or other exercises. Participants are assigned to each station, and they then rotate around the stations to the next with little or no rest performing 15 to 60 second workouts until all exercises have been completed or a certain time requirement achieved
