each time you use the weight bench. Replace
any worn parts immediately.
6. Keep children under the age of 12 and pets
away from the weight bench at all times.
7. Always wear athletic shoes for foot protection while exercising.
8. Keep hands and feet away from moving parts.
9. Always be sure there is an equal amount of

place more than 150 pounds on the leg lever.
12. When you are using the leg lever, place a
barbell with the same amount of weight on
the weight rests to balance the bench.
13. When you put weight on the weight rests,
make sure you put at least ten pounds on the
leg lever to balance the weight bench.
14. Make sure that the adjustment knobs are
inserted completely and tightened into the
uprights before beginning any exercise.
15. When adjusting the position of the seat,
make sure that the adjustment pin is inserted
through both adjustment tubes before beginning any exercise.
16. Always remove the curl post from the front
leg before performing leg exercises with the
leg lever.
17. If you feel pain or dizziness at any time while

ADJUSTING THE UPRIGHTS
The Weight Rests (6) can be adjusted to six heights
to accommodate different exercises. To adjust the
height, remove the Upright Knobs (18) from both
Weight Rests and Uprights (4, 5 [not shown]). Slide
the Weight Rests to the desired position and re-insert
the Upright Knobs.
WARNING: Always set both
Weight Rests (6) at the same height. Make
sure that the Upright Knobs (18) are inserted
completely and tightened into the Uprights (4,
5) before you begin any exercise.
ADJUSTING THE BACKREST
The Backrest (10) can be used in either a decline
position, a level position, or two incline positions. To
adjust the Backrest to the decline position, remove
the Backrest Pin (26) and lower the Backrest until it
rests directly on the Crossbar (3). Re-insert the
Backrest Pin into the adjustment tubes.
To adjust the Backrest (10) to the level position, insert
the Backrest Pin (26) through the top set of holes in
the adjustment tubes and the Frame (2). Secure the
Backrest Pin with the Spring Clip (25).
To adjust the Backrest (10) to an incline position,
insert the Backrest Pin (26) through one of the lower
two sets of holes in the adjustment tubes and the
Frame (2). Secure the Backrest Pin with the Spring
Clip (25).

THE FOUR BASIC TYPES OF WORKOUTS
Muscle Building
To increase the size and strength of your muscles,
push them close to their maximum capacity. Your
muscles will continually adapt and grow as you progressively increase the intensity of your exercise. You
can adjust the intensity level of an individual exercise
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
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 repetitions 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 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.
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
Cross training is an efficient way to get a complete
and well-balanced fitness program. An 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 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 exercise will reshape and strengthen your body, and
develop your heart and lungs.
PERSONALIZING YOUR EXERCISE PROGRAM
Determining the exact length of time for each workout,
as well as the number of repetitions or sets completed, is an individual matter. It is important 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 delivering more oxygen to your muscles.
WORKING OUT
Each workout should include 6 to 10 different exercises. Select exercises for every major muscle group,
emphasizing areas that you want to develop 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
Maintaining proper form is an essential part of an
effective exercise program. 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 exhausted. On the exercise guide accompanying this manual you will find photographs showing the
correct form for several exercises, and a list of the
muscles affected. Refer to the muscle chart on page
13 to find the names 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.
EXERCISE GUIDELINES
13
Rest for a short period of time after each set. The ideal
resting periods are:
• Rest for three minutes after each set for a muscle
building workout.
• Rest for one minute after each set for a toning work-
out.
• Rest for 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
an effective way to increase flexibility.
STAYING MOTIVATED
For motivation, keep a record of each workout. List the
date, the exercises performed, the weight used, and
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.
