"Cardiovascular exercise is any type of exercise that increases the work of the heart and lungs," says Tommy Boone, PhD, a founding member of the American Society of Exercise Physiologists.
Adults should accumulate 30 minutes of moderate-intensity physical activity on most days of the week, and to improve cardiovascular endurance, 20 to 60 minutes on three to five days per week.
The best cardio exercise to do is the one you will do day in and day out. It is best to find a cardio exercise you will enjoy.
