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.
Workouts that are as little as 20 minutes per day can create a 12-hour mood boosting benefit, says Tamir, who often sees mood boosts happen within five minutes of starting your training session. For optimal mood boosting benefits, aim for 20 to 40 minutes of moderate exercise a day.
