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.
To benefit most from aerobic exercise, you should work out hard enough to raise your heart rate to its training zone (target heart rate) for at least 20 minutes on most days. This enhances your aerobic capacityâthat is, the ability of your cardiovascular system to deliver oxygen to the bodyâs cells during exercise.
