IMPORTANT PRECAUTIONS
WARNING:
To reduce the risk of serious injury, read the following important precau-
tions 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.
11. Do not use a barbell that is longer than six
feet with the weight bench.
12. Always be sure there is an equal amount of
weight on each side of your barbell when
you are using it. Always keep some weight
on both ends of the barbell when adding or
removing weights to prevent the barbell from
tipping.
2. It is the responsibility of the owner to ensure
that all users of the weight bench are ade-
quately informed of all precautions.
3. The weight bench is intended for home use
only. Do not use the weight bench in any
commercial, rental, or institutional setting.
13. When you are using the leg lever, place a
barbell with the same amount of weight on
the weight rests to balance the bench.
4. Use the weight bench only on a level surface.
Cover the floor beneath the weight bench to
protect the floor.
14. Always exercise with a partner. When you
are performing bench press exercises, your
partner should stand behind you to catch the
barbell if you cannot complete a repetition.
5. Make sure all parts are properly tightened
each time the weight bench is used. Replace
any worn parts immediately.
15. Make sure that the adjustment knobs are
inserted completely and tightened into the
uprights before beginning any exercise.
6. Make sure the set screws attaching the
Olympic adapters are properly tightened
each time the adapters are used.
16. 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.
7. Keep children under 12 and pets away from
the weight bench at all times.
8. Always wear athletic shoes for foot protec-
tion while exercising.
17. Always remove the curl post from the front
leg before performing leg curls with the leg
lever.
9. Keep hands and feet away from moving
parts.
18. Do not sit on the top end of the backrest;
this will cause the weight bench to tip.
10. The weight bench is designed to support a
maximum user weight of 300 pounds, and a
maximum total weight of 610 pounds. Do not
place more than 310 pounds, including a bar-
bell and weights, on the weight rests. Do not
place more than 150 pounds on the leg lever.
Note: The weight bench does not include a
barbell or weights.
19. If you feel pain or dizziness at any time while
exercising, stop immediately and begin cool-
ing down.
WARNING:
Before beginning this or any exercise program, consult your physician. This
is especially important for persons over the age of 35 or persons with pre-existing health problems.
Read all instructions before using. Sears assumes no responsibility for personal injury or property
damage sustained by or through the use of this product.

ASSEMBLY
• As you assemble the weight bench, make sure all
parts are oriented as shown in the drawings.
Make Things Easier for Yourself
Everything in this manual is designed to ensure
that the weight bench can be assembled suc-
cessfully by anyone. However, it is important to
realize that the versatile weight bench has many
parts and that the assembly process will take
time. Most people find that by setting aside plen-
ty of time, assembly will go smoothly.
• For help identifying small parts, use the PART
IDENTIFICATION CHART on page 5.
The following tools (not included) are required
for assembly:
• Two adjustable wrenches
• One rubber mallet
Before beginning assembly, carefully read the
following information and instructions:
• One standard screwdriver
• One Phillips screwdriver
• Assembly requires two people.
• Lubricant, such as grease or petroleum jelly,
and soapy water.
• Place all parts in a cleared area and remove the
packing materials. Do not dispose of the packing
materials until assembly is completed.
Assembly will be more convenient if you have a
socket set, a set of open-end or closed-end
wrenches, or a set of ratchet wrenches.
• Tighten all parts as you assemble them, unless
instructed to do otherwise.

or dizziness at any time while exercising, stop immedi-
ately 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 pro-

depends upon the individual user. You must gauge
your limits and select the amount of resistance that is

Weight Loss
To lose weight, use a low amount of resistance and
increase the number of repetitions in each set.
Exercise for 20 to 30 minutes, resting for a maximum
of 30 seconds between sets.

well-balanced fitness program. An example of a bal-
anced program is:
• Plan strength training workouts on Monday,
Wednesday, and Friday.
• Plan 20 to 30 minutes of aerobic exercise, such as
running on a treadmill or riding on an elliptical or
exercise bike, on Tuesday and Thursday.
Exercising in an uncontrolled manner will leave you
feeling exhausted. On the exercise guide accompany-
ing this manual you will find photographs showing the
correct form for several exercises, and a list of the
muscles affected. See the muscle chart on the next
page to find the names of the muscles.

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.
• Rest for one minute after each set for a toning work-
out.
STAYING MOTIVATED
• 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.
For motivation, keep a record of each workout. List the
date, the exercises performed, the resistance 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 achiev-
ing the greatest results is to make exercise a regular
and enjoyable part of your everyday life.
COOLING DOWN
End each workout with 5 to 10 minutes of stretching.
Include stretches for both your arms and legs. Move
