Aerobic fitness means increasing how well the
body uses oxygen, which depends on the condition of the heart, lungs, and muscles.
Experts tend to describe aerobic activity in three ways: light, moderate, and vigorous.
people do moderate-intensity activities, they notice a faster heartbeat. To get the
benefits of moderate activity, a person can:
briskly (10 to 12 miles per hour [mph]).
without using a cart.
Sail or windsurf.
Mow the lawn (but don't use a riding mower).
vacuum, or mop.
The goal of aerobic fitness is to increase the amount
of oxygen that goes to the heart and muscles, which allows them to work longer. Any
activities, including many kinds of daily activities, that raise the heart rate and
keep it up for an extended period of time can improve aerobic fitness. If the activities
are done regularly and long enough, they can help improve fitness.
that adults try to do moderate activity for at least 2½ hours a week. Or they can
do vigorous activity for at least 1¼ hours a week. You can choose to do one or both
types of activity. And it's fine to be active in blocks of 10 minutes or more throughout
the day and week. Children as young as preschool age benefit from being active. It's
best for teens and children (starting at age 6) to do moderate to vigorous activity
at least 1 hour every day.
Moderate activity is safe for most people, but it's
always a good idea to talk to your doctor before starting an exercise program.
