Physical activity increases the amount of energy you use.
Although most weight-loss programs incorporate an exercise program—such as
jogging or biking—you can also use more energy by changing some everyday
activities, such as washing your car yourself instead of going to a car wash.
Participating in social activities that increase activity, such as joining a
gardening club or dancing, also increases your energy use. Strength training is
also an important part of a weight-loss program.
Always have a
medical evaluation before starting any new physical activity. If you have chest
pain or dizziness during any physical activity, stop and call your
If you have not exercised much in the past, your doctor
might first recommend a small amount of daily aerobic activity. For weight loss, though, experts advise doing
moderate activity for at least 5 hours a week.1 Try for 60 to 90 minutes a day, at least 5 days a week. It's fine to be active in blocks of 10 minutes
or more throughout your day and week. And you can choose to do one or both

improve your aerobic conditioning. You can exercise at one time or throughout
the day, whichever is most convenient. For example, you could walk for 10
minutes at one time and garden for 20 minutes later on, which would give you 30
minutes of activity for the day.

When choosing an exercise program or physical activity, pick
something you like. Don't pick what looks easiest, what your friends do, or
what the fad is. If you enjoy your activity, it will be easier to do and you
will be more likely to stay with it. Also think about whether you would rather
have convenience or companionship while being physically active. Some people
want something they can do anytime with little hassle. Examples include a
treadmill in the home, going for a walk in the neighborhood, or gardening.
Others might prefer companionship, which means scheduling times with others.
Very often when you share your activity with someone, you keep each other on
