Most likely true about cardio fitness is that it is the ability of the heart, lungs, and blood vessels to supply oxygen to the muscles during sustained physical activity. It improves overall cardiovascular health, strengthens the heart muscles, and increases lung capacity. Cardiorespiratory exercises, such as running, swimming, cycling, or brisk walking, are often recommended to improve cardio fitness. Regular cardiovascular exercise can help reduce the risk of chronic diseases, improve endurance, boost energy levels, and contribute to weight management.
