IMPORTANT PRECAUTIONS
WARNING:To reduce the risk of serious injury, read the following important precautions before using
the weight bench.
1. Read all instructions in this manual before
using the weight bench. Use the weight
bench only as described in this manual.
12. Always place 50 pounds on the leg lever
when performing squat exercises to balance
the bench (see page 15).
2. It is the responsibility of the owner to ensure
that all users of the weight bench are ade-
quately informed of all precautions.
13. Always fold the backrest out of the way when
performing squat exercises (see page 15). Do
not sit on the seat when the backrest is folded.
3. The weight bench is intended for home use
only. Do not use the weight bench in any
commercial, rental, or institutional setting.
14. Do not stand with your back to the weight
bench when performing squat exercises (see
page 15).You should be able to see the
weight rests while exercising so that you can
safely return the barbell (not included) to the
weight rests when you finish the exercise.
4. Use the weight bench only on a level surface.
Cover the floor beneath the weight bench for
protection.
15. When using the backrest, make sure that the
adjustment tube is fully inserted into the
adjustment brackets on the uprights.
5. Inspect and tighten all parts each time you
use the weight bench. Replace any worn
parts immediately.
16. Always remove the lat tower or curl post
from the front leg and place the 2” inner cap
over the open tube before performing leg
curl or leg extension exercises with the leg
lever (see page 15).
6. Keep children under 12 and pets away from
the weight bench at all times.
7. Keep hands and feet away from moving parts.
8. Always wear athletic shoes for foot protec-
tion while exercising.
17. Always set both weight rests at the same
height. The long adjustment knob must
always be inserted through both the weight
rest and upright and firmly tightened. Never
tighten the long adjustment knob into an
upright and then set a weight rest in the
upright on top of the long adjustment knob.
9. Do not use a barbell (not included) longer
than six feet with this weight bench.
10. Always be sure there is an equal amount of
weight on each side of your barbell (not
included) when you are using it.
18. Always exercise with a partner. When you are
performing bench press exercises, squat
exercises, or toe raise exercises, your partner
should stand behind you to catch the barbell
if you cannot complete a repetition.
11. The weight bench is designed to support a
maximum of 460 pounds, including the user,
a barbell, and weights. The preacher curl post
is designed to support a maximum of 50
pounds. Do not place more than 210 pounds, 19. If you feel pain or dizziness at any time while
including a barbell and weights, on the
weight rests; do not place more than 130
pounds on the weight carriage; do not place
more than 130 pounds on the leg lever for
normal use.
exercising, stop immediately and begin cool-
ing down.

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 “repeti-
tion” is one complete cycle of an exercise, such as
one sit-up. A “set” 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 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 on page 18 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

for 3 minutes after each set if you are doing a muscle
building workout, 1 minute after each set if you are
doing a toning workout, and 30 seconds after each
set if you are doing 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.
STAYING MOTIVATED
For motivation, keep a record of each workout. The
chart on page 19 of this manual can be photocopied
and used to schedule and record your workouts. List
the date, exercises performed, weight, and numbers
of 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 stretch—do not bounce. Ease into each
stretch gradually and go only as far as you can with-
out 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.
