What characterizes circuit training?

Circuit training is characterized by a series of exercises performed in rotation, allowing participants to engage in a full-body workout that typically combines strength training and aerobic exercises. This approach not only maximizes the benefits of a workout by targeting different muscle groups but also keeps the heart rate elevated, which can improve cardiovascular fitness and endurance. Circuit training can include a variety of movements, such as push-ups, jumping jacks, and squats, and can be adjusted for intensity to suit the fitness level of the participants.

Other options describe different types of workouts but do not fit the definition of circuit training. For instance, long-distance running focuses specifically on endurance and aerobic capacity, a single exercise performed until fatigued emphasizes strength training but lacks the variety characteristic of circuit training, and yoga training involves flexibility and balance rather than the dynamic combination of exercises found in a circuit format.
