In strength training programs, what is the primary benefit of circuit training?

Circuit training is primarily designed to improve muscular endurance. This is achieved by organizing a series of exercises performed one after the other with minimal rest in between. The continuous nature of circuit training keeps the heart rate elevated, enhances stamina, and allows for multiple muscle groups to be engaged within a single session.

By focusing on lighter weights with higher repetitions, circuit training conditions the muscles to withstand longer periods of exertion. This approach builds endurance more effectively than traditional strength training methods, which often emphasize maximal strength through lower repetitions and heavier weights. While circuit training can contribute to other benefits, such as fat loss and cardiovascular fitness, its distinct advantage lies in its ability to enhance muscular endurance specifically through sustained activity and repetitive motion.
