A Dr. Kelly Traver , Internal Medicine, answered. To increase aerobic (cardiorespiratory) fitness, do higher-intensity workouts that get you up to 60 to 80 percent of your maximum heart rate for at least 20 to 30 minutes three times a week. This should be in addition to your base activity of 30 minutes a day.
Activity begins with a warm-up section to allow pulse rates to gradually increase from resting to higher training levels. Heart rates increase to reach training zones between 120 and 160 beats per minute. Training zones vary according to age, resting heart rate and the activity levels. In order to improve cardiovascular fitness, workouts need to remain in the training zones for 20 to 30 minutes.
