What type of training focuses on exercises performed in a specific order for a set time?

The correct choice is circuit training, which is characterized by a series of exercises performed in succession, targeting different muscle groups, with minimal rest in between. This training method allows for a comprehensive workout that can improve strength, endurance, and overall fitness simultaneously.

Circuit training is typically organized in a way that each exercise is done for a predetermined amount of time or repetitions, followed by a brief rest before moving on to the next exercise. This structure makes it effective for combining cardiovascular and muscular training, leading to a high-intensity workout that keeps the heart rate elevated.

The other options, while focusing on different aspects of fitness, do not fit this specific format. Cardio training generally emphasizes continuous aerobic exercise without the structured sequence found in circuit training. Plyometric training involves explosive movements designed to increase power and is not performed in a timed sequence of varied exercises. Powerlifting, on the other hand, focuses on lifting the maximum weight in specific lifts (squat, bench press, and deadlift) rather than performing a variety of exercises in a circuit format.
