CONDITIONING GUIDELINES
The following guidelines will help you to plan your
exercise program. Remember that proper nutrition
and adequate rest are essential for successful results.
EXERCISE INTENSITY
Whether your goal is to burn fat or to strengthen your
cardiovascular system, the key to achieving the
desired results is to exercise with the proper intensity.
The proper intensity level can be found by using your
heart rate as a guide. The chart below shows recom-
mended heart rates for fat burning, maximum fat
burning, and cardiovascular (aerobic) exercise.
To find the proper heart rate for you, first find your age
at the bottom of the chart (ages are rounded off to the
nearest ten years). Next, find the three numbers
above your age. The three numbers are your Òtraining
zone.Ó The smallest number is the recommended
heart rate for fat burning; the middle number is the
heart rate for maximum fat burning; the largest
number is the heart rate for aerobic exercise.
Burning Fat
To burn fat effectively, you must exercise at a rela-
tively low intensity level for a sustained period of time.
During the first few minutes of exercise, your body
uses easily accessible carbohydrate calories for ener-
gy. Only after the first few minutes of exercise does
your body begin to use stored fat calories for energy.
If your goal is to burn fat, adjust the intensity of your
exercise until your heart rate is near the smallest
number in your training zone as you exercise.
For maximum fat burning, adjust the intensity of your
exercise until your heart rate is near the middle num-
ber in your training zone as you exercise.
Aerobic Exercise
If your goal is to strengthen your cardiovascular sys-
tem, your exercise must be Òaerobic.Ó Aerobic exer-
cise is activity that requires large amounts of oxygen
for prolonged periods of time. This increases the
demand on the heart to pump blood to the muscles,
and on the lungs to oxygenate the blood. For aerobic
exercise, adjust the intensity of your exercise until
your heart rate is near the largest number in your
training zone.
HOW TO MEASURE YOUR HEART RATE
To measure your heart rate, first exercise for at least
four minutes. Then, stop exercising and place two
fingers on your
wrist as shown.
Take a six-second
heartbeat count,
and multiply the
result by 10 to find
your heart rate.
For example, if
your six-second
heartbeat count is
14, your heart rate
is 140 beats per
minute. (A six-second count is used because your
heart rate will drop rapidly when you stop exercising.)
WORKOUT GUIDELINES
Each workout should include the following three
important parts:
A warm-up, consisting of 5 to 10 minutes of stretch-
ing and light exercise. (See page 13.) A proper warm-
up increases your body temperature, heart rate, and
circulation in preparation for exercise.
WARNING: Before beginning this or any exer-
cise program, consult your physician. This is
especially important for persons over the age
of 35 or persons with pre-existing health
problems.

13
SUGGESTED STRETCHES
The correct form for several basic stretches is shown at the
right. Move slowly as you stretchÑnever bounce.
1. Toe Touch Stretch
Stand with your knees bent slightly and slowly bend forward
from your hips. Allow your back and shoulders to relax as you
reach down toward your toes as far as possible. Hold for 15
counts, then relax. Repeat 3 times. Stretches: Hamstrings,
back of knees, and back.
2. Hamstring Stretch
Sit with one leg extended. Bring the sole of the opposite foot
toward you and rest it against the inner thigh of your extended
leg. Reach toward your toes as far as possible. Hold for 15
counts, then relax. Repeat 3 times for each leg. Stretches:
Hamstrings, lower back, and groin.
3. Calf/Achilles Stretch
With one leg in front of the other, reach forward and place
your hands against a wall. Keep your back leg straight and
your back foot flat on the floor. Bend your front leg, lean for-
ward and move your hips toward the wall. Hold for 15 counts,
then relax. Repeat 3 times for each leg. To cause further
stretching of the achilles tendons, bend your back leg as well.
Stretches: Calves, achilles tendons, and ankles.
4. Quadriceps Stretch
With one hand against a wall for balance, reach back and
grasp one foot with your other hand. Bring your heel as close
to your buttocks as possible. Hold for 15 counts, then relax.
Repeat 3 times for each leg. Stretches: Quadriceps and hip
muscles.

4
Training zone exercise, consisting of 20 to 30
minutes of exercising with your heart rate in your
training zone. (During the first few weeks of your
exercise program, do not keep your heart rate in
your training zone for longer than 20 minutes.)
A cool-down, with 5 to 10 minutes of stretching.
This will increase the flexibility of your muscles
and will help to prevent post-exercise problems.
EXERCISE FREQUENCY
To maintain or improve your condition, plan three work-
outs each week, with at least one day of rest between
workouts. After a few months of regular exercise, you
may plan up to five workouts each week, if desired.
Caution: Be sure to progress at your own pace
and avoid overdoing it. Incorrect or excessive
training may result in injury to your health.
Remember, the key to success is make exercise a
regular and enjoyable part of your everyday life.
