This activity burns approximately 696 calories per hour

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.

Made popular in the US by Curves facilities, circuit training is suitable for all levels of ability, age, or fitness level because participants can work at their own level, performing each exercise at their own speed and intensity. Beginners can develop their technique under the direction of the instructor, which can then be applied to good effect when working on their own in the gym. Advanced participants can build up to very high levels of intensity or reps while enjoying the atmosphere of a group exercise activity without having to conform to the set routines of an aerobics class.
