The term 'cardio' encompasses various exercises that elevate heart rate and promote cardiovascular health. These activities include running, cycling, swimming, and aerobic classes, focusing on endurance and stamina. Cardio workouts can be performed in steady-state or interval formats, each providing unique benefits. Engaging in regular cardio supports weight management, improves lung capacity, and enhances overall energy levels. Additionally, cardiovascular training is linked to better mental health, as it can reduce symptoms of anxiety and depression. Therefore, incorporating cardio into fitness routines is essential for holistic health.
