Chapter 4: Sample Exercises
Making It Work
There
are lots of ways to increase your physical activity. Exercising at
home is just one of them, and we feature it here because it’s
within the reach of most older people. Or, you might decide to
follow Phyllis Wendahl’s example, instead, and do something
different.
Ms. Wendahl is 85 years old and lives in the small town of
Bothell, Washington. On the phone, she sounds much younger. She is
a widow and lives on her Social Security income, and, like many
older adults, she won’t let her kids spoil her as much as
they would like to. She would rather do things on her own.
That’s why, when she was scouting around for a fitness
club where she could use strength-building equipment, she bargained
the owner down to a monthly fee that she felt she could afford
— $25 a month for unlimited use.
“Look, I know that not everybody is as bold as I am about
that kind of thing,” Ms. Wendahl told us. Nonetheless, she
has some advice for older adults who are thinking about going to a
fitness center: “They don’t need to feel self-conscious
about going to the club. The owner of my club holds me up as an
example now.”
Ms. Wendahl said that she has always been active, but never as
much as she is now. She began doing aerobic exercises in her 70s,
moved on to water aerobics, and most recently to strength-building
and stretching 3 times a week. She lives on her own and drives
herself wherever she needs to go. After 6 months of endurance and
strength exercises, measurements showed that Ms. Wendahl was able
to perform household tasks — carrying groceries, making her
bed, and transferring laundry — more quickly. She could also
carry more weight.
“It has just done me a world of good,” she said of
her physically active lifestyle. “My family is so thrilled
and proud of me,” she added.
She wants older adults who read this book to know that, when it
comes to exercise and physical activity, “there’s
always something within someone’s capabilities. There’s
no reason older people need to be sitting in a rocking
chair.”

Many different physical
activities can improve your health and independence. Whether you
choose to do the exercises shown in this chapter or other
activities that accomplish the same goals, gradually work your way
up to include endurance, strength, balance, and stretching
exercises.

How Hard Should I Exercise?
We can’t tell you exactly how many pounds to lift or how
steep a hill you should climb to reach a moderate or vigorous level
of exercise, because what is easy for one person might be strenuous
for another. It’s different for different people.
We can, however, provide some advice based on scientific
research: Listen to your body. The level of effort you feel you are
putting into an activity is likely to agree with actual physical
measurements. In other words, if your body tells you that the
exercise you are doing is moderate, measurements of how hard your
heart is working would probably show that it really is working at a
moderate level. During moderate activity, for instance, you can
sense that you are challenging yourself but that you aren’t
near your limit.
One
way you can estimate how hard to work is by using the Borg Category
Rating Scale. It was named after Gunnar Borg, the scientist who
developed it. The numbers on the left of the scale don’t
indicate how many times or how many minutes you should do an
activity; they help you describe how hard you feel you are
working.
For endurance activities, you should
gradually work your way up to level
13 — the feeling that you are working at a somewhat
hard level. Some people might feel that way when they are walking
on flat ground; others might feel that way when they are jogging up
a hill. Both are right. Only you know how hard your
exercise feels to you.
Strength exercises are higher on the Borg
scale. Gradually work your way up to level
15 to 17 — hard to very hard — to build muscle
effectively. You can tell how hard an effort you are making by
comparing it to your maximum effort. How hard does your current
effort feel compared to when you are lifting the heaviest weight
you can lift? Once you start exerting more than a moderate amount
of effort in your muscle-building exercises, your strength is
likely to increase quickly.
As your body adapts and you become more fit, you can gradually
keep making your activities more challenging. You might find, for
example, that walking on a flat surface used to feel like you were
working at level 13 on the Borg scale, but now you have to walk up
a mild hill to feel like you are working at level 13. Later, you
might find that you need to walk up an even steeper slope to feel
that you are working at level 13.
The Borg scale is simple to use. But if your level of effort
doesn’t match the numbers you see on the Borg scale —
for example, if you think you are doing the exercises correctly,
but you aren’t progressing or you are exhausted by your
effort — check with a fitness professional. These experts are
likely to understand the science that went into developing the Borg
scale, and they can teach you how to match your level of effort
with the right number on the scale.

Here are some points to
keep in mind as you begin increasing your activity:
- If you stop exercising
for several weeks and then return, start out at about half the
effort you were putting into it when you stopped, then gradually
build back up. Some of the effects of endurance and muscle-building
exercises deteriorate within 2 weeks if these activities are cut
back substantially, and benefits may disappear altogether if they
aren’t done for 2 to 8 months.
- When an exercise calls
for you to bend forward, bend from the hips, not the waist. If you
keep your entire back and shoulders straight as you bend forward,
that will help ensure that you are bending the right way, from the
hips. If you find your back or shoulders humping in any spot as you
bend forward, that’s a sign that you are bending incorrectly,
from the waist. Bending from the waist may cause spine fractures in
some people with osteoporosis.
- It’s possible to
combine exercises. For example, regular stair-climbing sessions
improve endurance and strengthen leg muscles at the same
time.
How to Improve Your
Endurance
Endurance exercises are
any activity — walking, jogging, swimming, raking —
that increases your heart rate and breathing for an extended period
of time.
How Much, How
Often
- Build up your
endurance gradually, starting out with as little as 5
minutes of endurance activities at a time, if you need
to.
- Starting out at a lower
level of effort and working your way up gradually is especially
important if you have been inactive for a long time. It may
take months to go from a very long-standing sedentary lifestyle to
doing some of the activities suggested in this
section.
- Your goal is to work
your way up, eventually, to a moderate-to-vigorous level that
increases your breathing and heart rate. It should feel
somewhat hard to you (level 13 on the Borg
scale).
- Once you reach your
goal, you can divide your exercise into sessions of no less
than 10 minutes at a time, if you want to, as long as they
add up to a total of a minimum of 30 minutes at the end of the day.
Doing less than 10 minutes at a time won’t give you the
desired cardiovascular and respiratory system benefits. (The
exception to this guideline is when you are just beginning to do
endurance activities.)
- Your goal is to build
up to a minimum of 30 minutes of endurance exercise on most
or all days of the week. More often is better, and every
day is best.
Safety
- Endurance activities
should not make you breathe so hard that you can’t talk. They
should not cause dizziness or chest pain.
- Do a little light
activity before and after your endurance exercise session, to warm
up and cool down (example: easy walking).
- Stretch after
your endurance activities, when your muscles are warm.
- As you get older, your
body may become less likely to trigger the urge to drink when you
need water. In other words, you may need water, but you won’t
feel thirsty. Be sure to drink liquids when you are doing any
activity that makes you lose fluid through sweat. The rule of thumb
is that, by the time you notice you are thirsty, you are already
somewhat dehydrated (low on fluid). This guideline is important
year-round, but is especially important in hot weather, when
dehydration is more likely. If your doctor has asked you to limit
your fluids, be sure to check with him or her before increasing the
amount of fluid you drink while exercising. Congestive heart
failure and kidney disease are examples of chronic diseases that
often require fluid restriction.
- Older adults can be
affected by heat and cold more than other adults. In extreme cases,
exposure to too much heat can cause heat stroke, and exposure to
very cold temperatures can lead to hypothermia (a dangerous drop in
body temperature). If you are exercising outdoors, dress in layers
so you can add or remove clothes as needed.
- Use safety equipment to
prevent injuries. For example, wear a helmet for bicycling, and
wear protective equipment for activities like skiing and skating.
If you walk or jog, wear stable shoes made for that
purpose.
Progressing
When you are ready to progress, build up the amount of time you
spend doing endurance activities first; then build up the
difficulty of your activities later. Example: First, gradually
increase your time to 30 minutes over several days to weeks (or
even months, depending on your condition) by walking longer
distances, then start walking up steeper hills or walking more
briskly.

Tips on How to Gauge Your Effort
Here are some informal guidelines you can use to estimate how much
effort you are putting into your endurance activities.
- Talking doesn’t take much effort during moderate
activity. During vigorous activity, talking is difficult.
- If you tend to perspire, you probably won’t sweat during
light activity (except on hot days). You will sweat during vigorous
or sustained moderate activity.
- Your muscles may get a rubbery feeling after vigorous activity,
but not after moderate activity.
- One doctor who specializes in exercise for older adults tells
her patients this about how hard they should work during endurance
activities: “If you can’t talk while you’re
exercising, it’s too difficult. If you can sing a song from
an opera, it’s too easy!”

skiing
- Downhill
skiing
- Hiking

How to Improve Your
Strength
Even very small changes
in muscle size can make a big difference in strength, especially in
people who already have lost a lot of muscle. An increase in muscle
that’s not even visible to the eye can be all it takes to
improve your ability to do things like get up from a chair or climb
stairs.
Your muscles are active
even when you are sleeping. Their cells are still doing the routine
activities they need to do to stay alive. This work is called
metabolism, and it uses up calories. That can help keep your weight
in check, even when you are asleep!
About Strength
Exercises
To do most of the following strength exercises, you need to lift or
push weights, and gradually you need to increase the amount of
weight you use. You can use the hand and ankle weights sold in
sporting-goods stores, or you can use things like emptied milk jugs
filled with sand or water, or socks filled with beans and tied shut
at the ends.
There are many
alternatives to the exercises shown here. For example, you can buy
a resistance band (it looks like a giant rubber band, and
stretching it helps build muscle) at a sporting-goods store to do
other types of strength exercises. Or you can use the special
strength-training equipment at a fitness center.

How Muscles Work
What makes your muscles look bigger when you flex them - when you
"make a muscle" with your biceps, for example?
Muscle cells contain long strands of protein lying next to each
other. When you want your muscles to move, your brain signals your
nerves to stimulate them. A chemical reaction in your muscles
follows, causing the long strands of protein to slide toward and
over each other, shortening the length of your muscle cells. When
you "make a muscle" and you see your muscle bunch up and bulge, you
are actually watching it shorten as the protein strands slide over
each other.
When you do challenging muscle-building exercises on a regular
basis, the bundles of protein strands inside your muscle cells grow
bigger.
|
How Much, How
Often
- Do strength exercises
for all of your major muscle groups at least twice a
week. Don’t do strength exercises of the same muscle
group on any 2 days in a row.
- Depending on your
condition, you might need to start out using as little as 1 or 2
pounds of weight, or no weight at all. The tissues that bind the
structures of your body together need to adapt to strength
exercises.
- Use a minimum
of weight the first week, then gradually add weight.
Starting out with weights that are too heavy can cause
injuries.
- Gradually add a
challenging amount of weight in order to benefit from strength
exercises. If you don’t challenge your muscles, you
won’t benefit from strength exercises. (The
“Progressing” section will tell you how.)
- When doing a strength
exercise, do 8 to 15 repetitions in a row. Wait a minute, then do
another set of 8 to 15 repetitions in a row of the
same exercise. (Tip: While you are waiting, you might want to
stretch the muscle you just worked or do a different strength
exercise that uses a different set of muscles).
- Take 3 seconds
to lift or push a weight into place; hold the
position for 1 second, and take another 3 seconds
to lower the weight. Don’t let the weight drop;
lowering it slowly is very important.
- It should feel
somewhere between hard and very hard (15 to 17 on the Borg scale)
for you to lift or push the weight. It should not feel very, very
hard. If you can’t lift or push a weight 8 times in a row,
it’s too heavy for you. Reduce the amount of weight. If you
can lift a weight more than 15 times in a row, it’s too light
for you. Increase the amount of weight.
- Stretch after strength
exercises, when your muscles are warmed up. If you stretch before
strength exercises, be sure to warm up your muscles first (through
light walking and arm pumping, for example).

Practice Sitting Straight
Sit or stand with your shoulders back, but not pinched, and hold
this position while you take slow, deep breaths. You can do this
anytime.
|
Safety
- Don't hold your
breath during strength exercises. Breathe normally.
Holding your breath while straining can cause changes in blood
pressure. This is especially true for people with cardiovascular
disease.
- If you have had a hip
repair or replacement, check with your surgeon before doing
lower-body exercises.
- If you have had a hip
replacement, don't cross your legs, and don't bend your hips
farther than a 90-degree angle.
- Avoid jerking or
thrusting weights into position. That can cause injuries. Use
smooth, steady movements.
- Avoid "locking" the
joints in your arms and legs in a tightly straightened position. (A
tip on how to straighten your knees: Tighten your thigh muscles.
This will lift your kneecaps and protect them.)
- Breathe out as you lift
or push, and breathe in as you relax. For example, if you are doing
leg lifts, breathe out as you lift your leg, and breathe in as you
lower it. This may not feel natural at first, and you probably will
have to think about it as you are doing it for awhile.
- Muscle soreness lasting
up to a few days and slight fatigue are normal after
muscle-building exercises, but exhaustion, sore joints, and
unpleasant muscle pulling aren't. The latter symptoms mean you are
overdoing it.
- None of the exercises
you do should cause pain. The range within which you move your arms
and legs should never hurt.
Progressing
- Gradually increasing
the amount of weight you use is crucial for building
strength.
- When you are able to
lift a weight between 8 to 15 times, you can increase the amount of
weight you use at your next session.
- Here is an example of
how to progress gradually: Start out with a weight that you can
lift only 8 times. Keep using that weight until you become strong
enough to lift it 12 to 15 times. Add more weight so that, again,
you can lift it only 8 times. Use this weight until you can lift it
12 to 15 times, then add more weight. Keep repeating.
Sarcopenia: A
Word You Are Likely to Hear More About
We know that muscle-building exercises can improve strength in most
older adults, but many questions remain about muscle loss and
aging. Researchers want to know, for example, if factors other than
a sedentary lifestyle contribute to muscle loss. Does age itself
cause changes in the muscles of older people? Is muscle loss
related to changes in hormones or nutrition? The answers to these
questions may lead to ways of helping us keep our strength as we
age.
In this book, we use the
word "frailty" to describe the loss of muscle and strength often
seen in older people, because it's a word that most people are
familiar with. However, a better word to use is "sarcopenia"
(pronounced sar - ko - PEEN - ya). It means not only the loss of
muscle and strength but also the decreased quality of muscle tissue
often seen in older adults. You are likely to hear more about
sarcopenia in the future since it's a very active area of
research.

Chapter
Summary
- Build up to all
exercises and activities gradually, especially if you have been
inactive for a long time.
- Once you have built up
to a regular schedule, include endurance, strength, balance, and
stretching exercises.
- If you have to stop
exercising for more than a few weeks, start at half the effort when
you resume, then build back up to where you were.
- When bending forward,
always keep back and shoulders straight to ensure that you are
bending from the hips, not the waist.
- If you have had a hip
replacement, check with your surgeon before doing lower body
exercises.
Endurance
- To build stamina, you
can do specific exercises, like walking or jogging, or any activity
that raises your heart rate and breathing for extended periods of
time.
- Do at least 30 minutes
of endurance activities on most or all days of the
week.
- If you prefer, divide
your 30 minutes into shorter sessions of no less than 10 minutes
each.
- The more vigorous the
exercise, the greater the benefits.
- Warm up and cool down
with a light activity, such as easy walking.
- Activities
shouldn’t make you breathe so hard you can’t talk. They
shouldn’t cause dizziness or chest pain.
- When you are ready to
progress, first increase the amount of time, then the difficulty,
of your activity.
- Stretch after endurance
exercises.
Strength
- Do strength exercises
for all your major muscle groups at least twice a week, but not for
the same muscle group on any 2 days in a row.
- Gradually increasing
the amount of weight you use is the most important part of strength
exercise.
- Start with a low amount
of weight (or no weight) and increase it gradually.
- When you are ready to
progress, first increase the number of times you do the exercise,
then increase the weight at a later session.
- Do an exercise 8 to 15
times; rest a minute and repeat it 8 to 15 more times.
- Take 3 seconds to lift
and 3 seconds to lower weights. Never jerk weights into
position.
- If you can’t lift
a weight more than 8 times, it’s too heavy; if you can lift
it more than 15 times, it’s too light.
- Don’t hold your
breath while straining.
- These exercises may
make you sore at first, but they should never cause
pain.
- Stretch after strength
exercises.
Balance
- Add the following
modifications to your regularly scheduled lower-body strength
exercises: As you progress, hold onto the table or chair with one
hand, then one finger, then no hands. If you are steady on your
feet, progress to no hands and eyes closed. Ask someone to watch
you the first few times, in case you lose your balance.
- Don’t do extra
strength exercises to add these balance modifications. Simply add
the modifications to your regularly scheduled strength
exercises.
- Another way to improve
your balance is through “anytime, anywhere” balance
exercises. One example: Balance on one foot, then the other, while
waiting for the bus. Do as often as desired.
Stretching
- Stretching exercises
may help keep you limber.
- Stretching exercises
alone will not improve endurance or strength.
- Do stretching exercises
after endurance and strength exercises, when your muscles are
warm.
- If stretching exercises
are the only kind of exercise you are able to do, do them at least
3 times a week, up to every day. Always warm up your muscles
first.
- Do each exercise 3 to 5
times at each session.
- Hold the stretched
position for 10 to 30 seconds.
- Total session should
last 15 to 30 minutes.
- Move slowly into
position; never jerk into position.
- Stretching may cause
mild discomfort, but should not cause pain.
