Circuit training is a type of workout that combines different exercises into a sequence, or “circuit,” with each exercise targeting a different muscle group or fitness goal. In a circuit, you perform each exercise for a set amount of time or repetitions, with short rest periods between exercises. After completing one round of all exercises in the circuit, you can rest longer before starting another round.

The exercises in circuit training can include cardio (like jumping jacks or running in place), strength exercises (like squats, push-ups, or weights), and flexibility moves (like stretches). This type of training helps improve endurance, strength, and overall fitness because it keeps the heart rate up and engages multiple muscle groups.
