Which training method involves rotating upper and lower body muscle groups?

Circuit Training involves rotating upper and lower body muscle groups in a systematic way, allowing one set of muscles to recover while working another. This method typically includes a series of exercises performed in succession with minimal rest in between, promoting both strength and cardiovascular fitness. The combination of different exercises for various muscle groups helps maintain an elevated heart rate, contributing to the effectiveness of high-intensity interval training (HIIT).

In contrast, bodybuilding primarily focuses on developing muscle size and symmetry, often working muscle groups in isolation rather than alternating between upper and lower body exercises. Powerlifting focuses on maximal strength in the squat, bench press, and deadlift, typically training specific muscle groups without the extensive rotation of muscle areas. Endurance training is more geared toward activities that improve stamina and aerobic capacity, such as long-distance running or cycling, rather than a structured rotation between muscle groups.
