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 improve your fitness levels it's recommended you perform 20-60 minutes of cardio exercise at an intensity 60-90% maximal heart rate (220-age = maximal heart rate), 3-5 days a week.tart with 5 minutes at 65-75% max heart rate (this is classified as zone 1). Increase the intensity of the cardio workout until you reach 80-85% max heart rate (zone 2) and hold for 1 minute. Return to zone 1 for 5 minutes and repeat the cycle.
