This section explains how to adjust the weight bench. See the EXERCISE GUIDELINES on page 10 for impor-
tant information on how to get the most benefit from your exercise program. Also, refer to the accompanying
exercise poster to see the correct form for each exercise.
Inspect and tighten all parts each time you use the weight bench. Replace any worn parts immediately. The
weight bench can be cleaned with a damp cloth and a mild, non-abrasive detergent. Do not use solvents.
ADJUSTING THE BACKREST
The Backrest (8) can be used in a level position, two
inclined positions and a declined position. To adjust the
Backrest to a level position or an inclined position, insert
the Locking Pin (16) through one of the adjustment holes
in the backrest adjustment bracket and through the weld-
ed tube in the Main Frame (1).
To use the Backrest (8) in a declined position, remove the

THEFOURBASICTYPESOFWORKOUTS
MuscleBuilding
Theonlywaytoincreasethesizeandstrengthofyour
musclesisto pushthemclosetotheirmaximum
capacity.Whenyouprogressivelyincreasetheintensi-
tyofyourexercise, your muscles will continually adapt
and grow. You can tailor the individual exercise to the
proper intensity level in two ways:
•by changing the amount of weight used
• by changing the number of repetitions or sets per-
formed (A "repetition" is one complete cycle of an
exercise, such as one sit-up. A "set" is a series of
repetitions).
The proper amount of weight for each exercise obvi-
ously depends upon the individual user. You must
gauge your limits and select the amount of weight that
is right for you. Begin with 3 sets of 8 repetitions for
each exercise you perform. Rest for 3 minutes after
each set. When you can complete 3 sets of 12 repeti-
tions without difficulty, increase the amount of weight.
Toning
You can tone your muscles by pushing them to a
moderate percentage of their capacity. Select a mod-
erate 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.
Weight Loss
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.
Cross Training
Many people desire a complete and well-balanced fit-
ness program, and cross training is a very efficient
way to accomplish this. One example of a balanced
program is:
• Plan weight training workouts on Monday,
Wednesday and Friday.
• Plan 20 to 30 minutes of aerobic exercise, such as
cycling, running or swimming on Tuesday and
Thursday.
• Rest from both weight training and aerobic exercise
for at least one full day each week to give your body
time to regenerate.
The combination of weight training and aerobic exer-
cise will reshape and strengthen your body plus
develop your heart and lungs.
PERSONALIZING YOUR EXERCISE PROGRAM
Specifying the exact length of time for each workout,
as well as the number of repetitions or sets for each
exercise, is a highly individual matter. It is very impor-
tant to avoid overdoing it during the first few months of
your exercise program. You should progress at your
own pace and be sensitive to your body's signals. If
you experience pain or dizziness at any time while
exercising, stop immediately and begin cooling down.
Find out what is wrong before continuing. Remember
that adequate rest and a proper diet are important
factors in any exercise program.
WARMING UP
Begin each workout with 5 to 10 minutes of stretching
and light exercise to warm up. Warming up prepares
your body for more strenuous exercise by increasing
circulation, raising your body temperature and deliver-
ing more oxygen to your muscles.
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 workouts,
vary the exercises from session to session.
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
You will gain the greatest benefits from exercising by
maintaining proper form. This requires 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 exhaust-
ed. On the exercise poster accompanying this manual,
you will find photographs showing the correct form for
several exercises. A description of each exercise is
also provided, along with a list of the muscles affect-
ed. Refer to the muscle chart below to find the loca-
tions of the muscles.
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!
10

You should rest for a short period of time after each
set. The ideal resting periods are:
• Rest three minutes after each set for a muscle build-
ing workout
• Rest one minute after each set for a toning workout
• Rest 30 seconds after each set for a weight loss
workout
Plan to spend the first couple of weeks familiarizing
yourself with the equipment and learning the proper
form for each exercise.
COOLING DOWN
End each workout with 5 to 10 minutes of stretching.
Include stretches for both your arms and legs. Move
slowly as you stretch and do 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.
STAYING MOTIVATED
For motivation, keep a record of each workout. List
the date, the exercises performed, the weight plus the
numbers of sets and repetitions completed. Record
your weight and key body measurements at the end
of every month.
Remember, the key to achieving the greatest results
is to make exercise a regular and enjoyable part of
your everyday life.
