Cardio is an exercise that is designed to benefit heart health and blood vessels.
The amount of cardio needed for optimal heart health varies depending on factors such as age, fitness level, and overall health status.

Vigorous-intensity exercise includes activities such as running, swimming, and cycling at a high intensity.
Consistency is key for optimal heart health. It's important to maintain a regular exercise routine, and gradually increase the intensity and duration of workouts over time.
