Cultural Tip
In Brazil, 'cardio' is everyday slang for any aerobic activity—running, cycling, jump rope, etc. It’s common to hear it in informal settings like the gym or on social media. When speaking with a trainer, you can also say 'treino cardio' to sound more natural. Keep the tone casual; a more formal version would replace 'cardio' with 'exercício cardiovascular'.
