The Fitness Formula
There really is a
fountain of youth: It's
called exercise. How?
Let us count the ways:
In study after study,
regular workouts have
been proven to insulate
you from heart disease,
cancer, Alzheimer's,
stroke, and diabetes.
Exercise lowers blood
pressure, reduces body
fat, raises "good"
cholesterol, lowers
"bad" cholesterol,
improves blood flow,
keeps intestines and the
colon healthy, and
regulates key hormones.
To ensure you reap all
these benefits, we asked
leading experts on aging
and exercise to devise
the ultimate anti-aging
workout. All agreed that
it should include the
four cornerstones of age
prevention: consistent
cardio, intense
intervals, yoga, and
weight training. Start
now and you can turn
back the clock...for
life.
1. DO:
Consistent Cardio
The verdict is in:
People who exercise
almost daily really do
keep ticking longer.
When scientists pored
over data from the
famous Framingham Heart
Study of more than 5,000
women and men, they
discovered that active
folks lived nearly 4
years longer than their
inactive peers, largely
because they sidestep
heart disease--the
nation's leading killer.
Aerobic exercise such as
walking, biking,
jogging, and swimming
protects your heart by
lowering blood pressure,
reducing "bad"
cholesterol, and keeping
arteries flexible to
improve blood flow. Your
Rx: 30 minutes, 5 days a
week of
moderate-intensity
aerobic exercise. Work
at a pace that allows
you to talk freely; if
you can sing, you're not
exercising hard enough.
To get started, choose
an activity you enjoy
and do 10 minutes, 5
days a week. Then
increase by 5 minutes
each week until you're
doing 30 minutes at a
time. Dividing your
exercise into three
10-minute bouts
throughout the day
works, too.
2. DO: Intense
Intervals
Exercise keeps
your mind fit by
bringing more blood and
oxygen to the noggin,
rejuvenating your brain
in the process. "The
hippocampus, the main
area of the brain where
memory resides, is
particularly susceptible
to damage from low blood
flow or lack of
oxygen--both of which
become more likely as we
age," says brain
researcher Eric B.
Larson, MD, of the Group
Health Cooperative in
Seattle. Doing bursts of
higher intensity
activity will increase
blood flow and oxygen
even more. Your Rx: 45
minutes, twice a week
(moderate-paced cardio
exercise interspersed
with 1-minute speed
bursts every 2 minutes).
Based on a 1-to-10
scale, you should feel
like you're working at
an intensity of 7 or 8
(brisk enough that you
can talk, but you'd
rather not) during the
speed bursts and an
intensity of 5 or 6
(moderate enough that
you can talk freely) the
rest of the time. If
you're just starting
out, do 15-second
intervals, slowly
building up to 1 minute
as your endurance
increases. Because this
is cardio exercise, you
don't have to do these
workouts on top of the
steady-paced cardio
session at left (though
you can if you have the
time, and you'll shape
up even faster). Just
extend two of those
workouts and make them
intervals.
3. DO: Weight
Training
A healthy heart
is key, but unless you
have strong bones and
muscles, getting up off
the couch, climbing the
stairs, and walking out
the door to enjoy life
won't be so easy.
Lifting weights is one
of the best ways to keep
these body systems in
tip-top shape, says
Wendy Kohrt, PhD, a
professor in the
division of geriatric
medicine at the
University of Colorado
Health Sciences Center
in Denver. And it can
help you stand tall--a
quick way to look
younger. Your Rx: 20
minutes, twice a week.
Pick up two sets of
dumbbells (3 and 5
pounds for beginners; 5
and 10 or 10 and 20 if
you need an even bigger
challenge), available at
most department stores
or sporting goods
stores.
4. DO: Yoga
The less tense
you are, the fewer lines
and wrinkles you'll
develop. One of the best
workouts to fight
stress? Yoga. In a
German study, 3 hours of
practice a week lowered
the anxiety levels of 16
women ages 26 to 51 by a
whopping 30%. "As your
mouth, jaw, and brows
relax, you can literally
see the creases soften,"
says Larry Payne, PhD,
director of the Yoga
Therapy Rx program at
Loyola Marymount
University. It may also
protect against free
radicals, compounds that
break down skin's
elasticity. Your Rx: 30
minutes, four times a
week.
More Ways
Exercise Keeps You Young
It boosts your mood:
Cardio workouts up
levels of the brain's
feel-good
neurotransmitters like
serotonin and
norepinephrine.
It helps you sleep: The
rhythmic breathing and
relaxation of yoga and
tai chi help you fall
asleep and snooze
longer.
It keeps you slim:
Beyond burning calories,
exercise may also help
regulate the production
of leptin, the "fat
hormone" that controls
appetite.
It firms you up: Lifting
weights builds
muscle--the magic tissue
needed to counteract
gravity and prevent
sagging.
It charges up your sex
life: Hormonal changes
as you age can lower
libido, but just 20
minutes of exercise gets
you in the mood by
increasing blood flow to
the genitals.
