Exercise Guidelines
THE FOUR BASIC TYPES OF WORKOUTS
¥ Muscle Building
PERSONALIZING YOUR EXERCISE PROGRAM
We have not specified an exact length of time for
each workout, or a specific number of repetitions or
sets for each exercise. It is very important to avoid
overdoing it during the first few months of your exer-
cise program, and to progress at your own pace. If
you experience pain or dizziness at any time while
exercising, stop immediately and begin to cool down.
Find out what is wrong before continuing. Remember
that adequate rest and a proper diet are also impor-
tant.
In order to increase the size and strength of your
muscles, you must push your muscles to a high per-
centage of their capacity. You must also progressively
increase the intensity of your exercise so that your
muscles will continually adapt and grow. Each individ-
ual exercise can be tailored to the proper intensity
level by changing the amount of weight used, or the
number of repetitions or sets performed. (A Òrepeti-
tionÓ is one complete cycle of an exercise, such as
one sit-up. A ÒsetÓ is a series of repetitions performed
consecutively.)
WARMING UP
Begin each workout with 5 to 10 minutes of light
stretching and exercise to warm up. Warming up pre-
pares your body for exercise by increasing circulation,
raising your body temperature and delivering more
oxygen to your muscles.
The proper amount of weight for each exercise
depends upon the individual user. It is up to you to
gauge your limits. Select the amount of weight that
you think is right for you. Begin with 3 sets of 8 repeti-
tions for each exercise that you perform. Rest for 3
minutes after each set. When you can complete 3
sets of 12 repetitions without difficulty, increase the
amount of weight.
WORKING OUT
Each workout should include 6 to 10 different exercis-
es. Select exercises for every major muscle group,
with emphasis on the areas that you want to develop
the most. To give balance and variety to your work-
outs, vary the exercises from workout to workout.
¥ Toning
To tone your muscles, you must push your muscles to
a moderate percentage of their capacity. Select a
moderate amount of weight and increase the number
of repetitions in each set. Complete as many sets of
15 to 20 repetitions as possible without discomfort.
Rest for 1 minute after each set. Work your muscles
by completing more sets rather than by using high
amounts of weight.
Schedule your workouts for the time of day when your
energy level is the highest. Each workout should be
followed by at least one day of rest. Once you find the
schedule that is right for you, stick with it.
EXERCISE FORM
¥ Weight Loss
In order to obtain the greatest benefits from exercis-
ing, it is essential to maintain proper form.
To lose weight, use a low amount of weight and
increase the number of repetitions in each set.
Exercise for 20 to 30 minutes, resting for a maximum
of 30 seconds between sets.
Maintaining proper form means moving through the
full range of motion for each exercise, and moving
only the appropriate parts of the body. Exercising in
an uncontrolled manner will leave you feeling
exhausted. On the exercise poster accompanying this
manual, you will find photographs showing the correct
form for several exercises. A description of each exer-
cise is also provided, along with a list of the muscles
affected. Refer to the muscle chart on page 12 to find
the locations of the muscles.
¥ Cross Training
In the pursuit of a complete and well-balanced fitness
program, many have found that cross training is the
answer. We recommend that on Monday, Wednesday
and Friday, you plan weight training workouts. On
Tuesday and Thursday, plan 20 to 30 minutes of aero-
bic exercise, such as cycling, running or swimming.
Rest from both weight training and aerobic exercise
for at least one full day each week to give your body
time to regenerate. By combining weight training with
aerobic exercise, you can reshape and strengthen
your body, plus develop a stronger heart and lungs.
The repetitions in each set should be performed
smoothly and without pausing. The exertion stage of
each repetition should last about half as long as the
return stage. Proper breathing is important. Exhale
during the exertion stage of each repetition and inhale
during the return stroke; never hold your breath. Rest

sets and repetitions completed. Record your weight
and key body measurements at the end of every
month.
COOLING DOWN
End each workout with 5 to 10 minutes of stretching.
Include stretches for both your arms and legs. Move
slowly as you stretchÑdo not bounce. Ease into each
stretch gradually and go only as far as you can without
strain. Stretching at the end of each workout is very
effective for increasing flexibility.
Remember, the key to achieving the greatest results is
to make exercise a regular and enjoyable part of your
everyday life.
