Circuit training is designed to work you in all five of the main fitness categories: aerobic fitness, muscular strength, muscular endurance, flexibility and body composition.

When you circuit train, you want to focus on high intensity for the whole routine. That means little rest between exercises.

Circuit training is key to weight loss. It revs up activity in all the muscle cells, which increases the metabolic rate for up to 48 hours after the workout is over – meaning you burn calories while you are sitting around watching TV hours later.

You should try to at least 25 minutes per routine for the best results, according to the American College of Sports Medicine. As you improve, try increasing the circuit time for the cardio exercises in your routine from 40 seconds to one minute.
