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.
This equals 30 minutes of aerobic exercise five days per week, and this is the minimum amount of aerobic exercise required to sustain cardiovascular health. To build cardiovascular endurance, increase your cardiovascular training by 10 minutes weekly. After two months, you'll be performing over 230 minutes of aerobic exercise weekly, your heart will be stronger and you'll have more stamina and energy.
