Circuit training is a form of conditioning combining resistance training and high-intensity aerobics. It is designed to be easy to follow and target strength building as well as muscular endurance. An exercise "circuit" is one completion of all prescribed exercises in the program. When one circuit is complete, one begins the first exercise again for another circuit. Traditionally, the time between exercises in circuit training is short, often with rapid movement to the next exercise.
The types of aerobic exercises favoured by circuit trainers are targeted at maximum effect in the minimum time e.g. press-ups, leg raises, ski jumps, step-ups and shuttle runs are all excellent for elevating the heart beat rate.
These exercises also concentrate on muscle groups which use a lot of energy.
If you follow an aerobic work-station with a high repetition and strength station, you will sustain a raised heart rate and therefore get the best possible results.
Circuit training is excellent for developing good basic strength and body tone.
Circuit training tends to concentrate on "compound exercises", i.e. those that use more than one muscle group at a time. These "combined" exercises are generally more effective than spending time on one piece of gym equipment that focuses on one set of muscles only.
The type of rotational activity involved in circuit training is an excellent fat burner.
Circuit training is psychologically rewarding. Whatever your level of fitness, you can really push yourself and set your own goals in the knowledge that you've only got 60, 90, 120 seconds worth of any activity before you move on to the next.
The benefits of taking part in circuit training can be summed up in a few words

"Maximum results in the minimum time". It is probably one of the best methods of exercising as it provides excellent all round fitness, tone and strength.
