What is the term for a training system that combines strength and cardio exercises in a circuit?

The training system that combines strength and cardio exercises in a circuit is called circuit training.

In circuit training, a participant moves through a sequence of exercise stations, completing one exercise at each station before continuing to the next. A circuit may combine resistance movements such as squats, push-ups or bench presses with aerobic activities such as jogging, skipping or treadmill work. After finishing the stations, the participant may repeat the circuit.

The system was developed by R. E. Morgan and G. T. Anderson at the University of Leeds in England in 1953. Its defining feature is organization into a circuit, often with short transitions between exercises. The format can be adapted for beginners, athletes, group classes or home workouts by changing exercise selection, work periods, resistance and rest.

Circuit training is sometimes confused with Tabata or a superset. Tabata is a specific high-intensity interval format, while a superset usually pairs exercises with little rest. Circuit training is the broader station-based system and can include either strength or cardio emphasis—or both.
