Which training method involves completing a series of exercises in succession without resting in between?

Circuit training is the method that involves completing a series of exercises in succession without resting in between. This approach typically includes a variety of exercises targeting different muscle groups, allowing participants to move from one exercise to the next with minimal downtime. The structure of circuit training is designed to maintain an elevated heart rate, promoting cardiovascular fitness while also improving muscular strength and endurance. It's an effective way to achieve a comprehensive workout in a relatively short amount of time, making it a favored choice in many fitness programs.

In contrast, interval training focuses on alternating periods of high-intensity effort with periods of rest or lower-intensity exercise, rather than following a structured sequence of exercises without rest. Endurance training typically emphasizes prolonged activities at a steady pace, which does not align with the format of multiple exercises performed in sequence. Strength training usually concentrates on lifting weights to build muscle mass and increase strength, often involving rest periods between sets to allow for recovery. Thus, the distinctive characteristic of circuit training—moving continuously through various exercises without pauses—sets it apart as the correct answer in this context.
