Aerobic Exercise. The CDC suggests that adults get at least two hours and 30 minutes of moderate aerobic activity per week, or one hour and 15 minutes of vigorous exercise per week. This breaks down to about 30 minutes of exercise per day for at least five days per week. While two hours and 30 minutes of exercise may seem like a lot of time, it's fine to break up your physical activity into more manageable chunks of time, such as three sets of 10-minute intervals during the day.
