How
Much Exercise Is Enough?
START
SLOW, AND WORK UP
For
the greatest overall health benefits, experts recommend that
you do 20 to 30 minutes of aerobic activity three or more
times a week and some type of muscle strengthening activity
and stretching at least twice a week. However, if you are
unable to do this level of activity, you can gain substantial
health benefits by accumulating 30 minutes or more of moderate-intensity
physical activity a day, at least five times a week.
If
you have been inactive for a while, you may want to start
with less strenuous activities such as walking or swimming
at a comfortable pace. Beginning at a slow pace will allow
you to become physically fit without straining your body.
Once you are in better shape, you can gradually do more strenuous
activity.
Moderate-intensity
Activity
Moderate-intensity activities include some of the things you
may already be doing during a day or week, such as gardening
and housework. These activities can be done in short spurts
-- 10 minutes here, 8 minutes there. Alone, each action does
not have a great effect on your health, but regularly accumulating
30 minutes of activity over the course of the day can result
in substantial health benefits.
To
become more active throughout your day, take advantage of
any chance to get up and move around. Here are some examples:
-
Take
a short walk around the block
-
Rake leaves
-
Play actively with the kids
-
Walk up the stairs instead of taking the elevator
-
Mow the lawn
-
Take an activity break -- get up and stretch or walk around
-
Park your car a little farther away from your destination
and walk the extra distance
The
point is not to make physical activity an unwelcome chore, but
to make the most of the opportunities you have to be active.
Aerobic
Activity
Aerobic
activity is an important addition to moderate-intensity exercise.
Aerobic exercise is any extended activity that makes you breathe
hard while using the large muscle groups at a regular, even
pace. Aerobic activities help make your heart stronger and more
efficient. They also use more calories than other activities.
Some examples of aerobic activities include:
- Brisk
walking
-
Jogging
-
Bicycling
-
Swimming
-
Aerobic dancing
-
Racket sports
Using
Aerobic Equipment (i.e., treadmill, stationary bike):
To
get the most health benefits from aerobic activity, you should
exercise at a level strenuous enough to raise your heart rate
to your target zone. To find your target zone, use our target
heart rate calculator.
Your
heart should be beating within your target heart rate zone.
If your heart is beating faster than your target heart rate,
you are exercising too hard and should slow down. If your heart
is beating slower than your target heart rate, you should exercise
a little harder.
When
you begin your exercise program, aim for the lower part of your
target zone. As you get into better shape, slowly build up to
the higher part of your target zone. If exercising within your
target zone seems too hard, exercise at a pace that is comfortable
for you. You will find that, with time, you will feel more comfortable
exercising and can slowly increase to your target zone.
