cardio fitness

Cardio fitness, also known as cardiovascular endurance, refers to your heart, lungs, and blood vessels' ability to supply oxygen and nutrients to your muscles during sustained physical activity. It reflects how efficiently your body can perform aerobic exercises like walking, running, or cycling over time. Good cardio fitness means your heart and lungs work effectively, enabling you to exercise longer and recover faster. It’s an important indicator of overall health, reducing risks for heart disease, improving energy levels, and supporting weight management. Regular aerobic activity helps strengthen your cardiovascular system, enhancing your endurance and overall well-being.
