1. Read all instructions in this manual before

using the weight system. Use the weight sys-

tem only as described in this manual.

2. It is the responsibility of the owner to ensure

that all users of the weight system are ade-

quately informed of all precautions.

3. The weight system is intended for home use

only. Do not use the weight system in any

commercial, rental, or institutional setting.

4. Use the weight system only on a level sur-

face. Cover the floor beneath the weight sys-

tem to protect the floor.

5. Keep the weight system indoors, away from

moisture and dust. Do not put the weight

system in a garage or covered patio, or near

water.

6. Make sure all parts are properly tightened

each time the weight system is used.

Replace any worn parts immediately.

7. Keep children under 12 and pets away from

the weight system at all times.

8. The weight system is designed to support a

maximum user weight of 300 pounds.

9. Always wear athletic shoes for foot protec-

tion while exercising.

10. Keep hands and feet away from moving parts.

11. Make sure that the cables remain on the pul-

leys at all times. If the cables bind as you are

exercising, stop immediately and make sure

that the cables are on the pulleys. Replace all

cables at least every two years.

12. Always secure the weight stack with the lock

pin and lock after exercising to prevent

unauthorized use of the weight system (see

BEFORE YOU BEGIN

Thank you for selecting the versatile WEIDER®PRO

4250 weight system. The weight system offers an

impressive array of weight stations designed to devel-

op every major muscle group of the body. Whether

your goal is to tone your body, build dramatic muscle

size and strength, or improve your cardiovascular sys-

tem, the weight system will help you to achieve the

specific results you want.

For your benefit, read this manual carefully before

using the weight system. If you have questions after

reading this manual, call 1-800-4-MY-HOME®

(1-800-469-4663). To help us assist you, please note

the product model number and serial number before

calling. The model number is 831.154021. The serial

number can be found on a decal attached to the

weight system (see the front cover of this manual for

the location of the decal).

Before reading further, please review the drawing

below and familiarize yourself with the parts that are

labeled.

ASSEMBLED

DIMENSIONS:

Height: 77 in.

Width: 81 in.

Depth: 59 in.

Make sure you have the following tools:

• Two adjustable wrenches

• One standard screwdriver

• One phillips screwdriver

• One rubber mallet

• You will also need grease or petroleum jelly, a

small amount of soapy water, and clear tape or

masking tape.

Note: 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.

How to Identify Parts

To help you identify the small parts used in assembly,

we have included a PART IDENTIFICATION CHART

in the center of this manual. Place the chart on the

floor and use it to easily identify parts during each

assembly step. Note: Some small parts may have

been pre-attached. If a part is not in the parts

bag, check to see if it has been pre-attached.

How to Orient Parts

As you assemble the weight system, make sure all

parts are oriented exactly as shown in the drawings.

Tightening Parts

Tighten all parts as you assemble them, unless

instructed to do otherwise.

Questions?

If you have questions after reading these assembly

instructions, please call 1-800-4-MY-HOME®

(1-800-469-4663).

Assembly Requires Two Persons

For your convenience and safety, assemble the

weight system with the help of another person.

Set Aside Enough Time

Due to the many features of the weight system, the

assembly process will require several hours. By

setting aside plenty of time and by deciding to

make the task enjoyable, assembly will go smoothly.

You may want to assemble the weight system over

a couple of evenings.

Select a Location for the Weight System

Because of its weight and size, the weight system

should be assembled in the location where it will be

used. Make sure that there is enough room to walk

around the weight system as you assemble it.

How to Unpack the Box

To make assembly as easy as possible, we have

divided the assembly process into four stages. The

parts needed for each stage are found in individual

bags. Important: Wait until you begin each stage

to open the parts bag for that stage. Place all

parts of the weight system in a cleared area and

remove the packing materials. Do not dispose of

the packing materials until assembly is completed.

Make Assembly Easier for Yourself

Everything in this manual is designed to

ensure that the weight system can be assem-

bled successfully by anyone. Before begin-

ning assembly, make sure to read the

information on this page. This brief intro-

duction will save you much more time than

it takes to read it.

The Four Stages of the Assembly Process

Frame Assembly—You will begin by assembling

the base and the uprights that form the skeleton of

the weight system.

Arm Assembly—During this stage you will

assemble the arms and the leg lever.

63. Make sure that all parts have been properly tightened. The use of the remaining parts will be explained in

ADJUSTMENTS, beginning on the following page.

Before using the weight system, pull each cable a few times to make sure that the cables move smoothly

over the pulleys. If one of the cables does not move smoothly, find and correct the problem. IMPORTANT: If

the cables are not properly installed, they may be damaged when heavy weight is used. See the

CABLE DIAGRAMS on pages 26 and 27 of this manual for proper cable routing. If there is any slack

in the cables, you will need to remove the slack by tightening the cables. See MAINTENANCE on

page 28.

This section explains how to adjust the weight system. See the EXERCISE GUIDELINES on page 29 for important

information about how to get the most benefit from your exercise program. Also, see the accompanying exercise

guide to see the correct form for each exercise.

Make sure all parts are properly tightened each time the weight system is used. Replace any worn parts immediate-

ly. The weight system can be cleaned with a damp cloth and a mild, non-abrasive detergent. Do not use solvents.

CHANGING THE WEIGHT SETTING

To change the setting of the weight stack, insert the

Weight Pin (57) under the desired Weight (55). Insert

the Weight Pin so that the bent end touches the

weight stack. Turn the bent end down. Note: Be

careful not to scratch yourself when reaching

through the hole in the Shroud (10). Do not use

the Top Weight (56, not shown) by itself.

Note: Due to the cables and pulleys, the amount

of resistance at each exercise station may vary

from the weight setting. Use the WEIGHT

RESISTANCE CHART on page 25 to find the

approximate amount of resistance at each weight

station.

ATTACHING THE ACCESSORIES TO A PULLEY

STATION

Attach the Handle (93) to the Ab Cable (107) at the low

pulley station with a Cable Clip (95). For some exercis-

es, the Chain (94) should be attached between the

Handle and the Cable with two Cable Clips. Adjust the

length of the Chain between the Handle and the

Cable so that the Handle is in the correct starting

position for the exercise to be performed.

The Lat Bar (not shown), the Ab Strap (79), or the

Handle (93) can be attached at any pulley station in

the same manner. Always engage the Lock Plate (21)

when using the low pulley station (see USING THE

LOCK PLATE below).

USING THE LOCK PLATE

When using the low pulley station, engage the Leg

Pin (24) into the Leg Lever (4) and the Lock Plate

(21).

To use the Leg Lever (4), engage the Leg Pin (24)

into the Right Seat Frame (3) and the Lock Plate (21).

ADJUSTMENTS

ADJUSTING THE BACKREST

To adjust the position of the Press Backrest (113),

disengaging the Knob (43) from the Left Upright (26)

and move the Backrest to the desired position.

Reengage the Knob into the Left Upright and the

Backrest Frame (53). Make sure the Knob is fully

tightened.

LOCKING THE WEIGHT STACK

Lock the weight stack by inserting the Lock Pin (65)

through a Weight Guide (44) and securing the Lock

(48) onto the Lock Pin.

WEIGHT RESISTANCE CHART

The chart below shows the approximate weight resistance at each exercise station. “Top” refers to the 6 lb. top

weight. The other numbers refer to the 12.5 lb. weight plates. Weight resistance shown for the butterfly arm sta-

tion is for each arm. Note: The actual resistance at each station may vary due to differences in individual

weight plates as well as friction between the cables, pulleys, and weight guides.

CABLE DIAGRAMS

The cable diagrams below show the proper routing of the Butterfly Cable (106), the Ab Cable (107), the Short

Cable (108), the Press Cable (109), and the Weight Cable (110). Use the diagram to make sure that the cables

and the cable traps have been assembled correctly. If the cables have not been correctly routed, the weight

bench will not function properly and damage may occur. The numbers show the correct route for each cable.

Make sure that the cable traps do not touch or bind the cables.

Make sure all parts are properly tightened each time the weight system is used. Replace any worn parts imme-

diately. The weight system can be cleaned with a damp cloth and a mild, non-abrasive detergent. Do not use

solvents.

TIGHTENING THE CABLES

Woven cable, the type of cable used on the weight system, can stretch slightly when it is first used. If there is

slack in the cables before resistance is felt, the cables should be tightened. To tighten the cables, first insert the

weight pin into the middle of the weight stack. Slack can be removed from these cables several ways:

•See drawing 1. Tighten the M8 Nylon Locknut

(91) that connects the end of a cable to a “U”-

bracket (50).

•See drawing 1. Remove the M10 Nylon Locknut

(90) and the M10 x 50mm Bolt (64) from the

Cable Trap (68), the 90mm Pulley (63), the two

Half Finger Guards (66), and a “U”-bracket (50).

Reattach the Pulley, Cable Trap, and Finger

Guards to the other hole in the “U”-bracket. Make

sure that the Cable Trap and Finger Guards

are oriented as shown and that the cable and

Pulley move smoothly.

•See drawing 2. Remove the M10 Nylon Locknut

(90) and the M10 x 50mm Bolt (64) from the

Cable Trap (68), the 90mm Pulley (63), the two

Half Finger Guards (66), and the two Pulley

Plates (51). Reattach the Pulley, Cable Trap, and

Finger Guards to the next closer hole to the cen-

ter of the Pulley Plates. Make sure that the

Cable Trap is oriented to hold the cable in the

groove of the Pulley, that the Finger Guards

are oriented as shown, and that the Cable and

Pulley move smoothly.

•See drawing 3. Loosen the M12 Nut (49) on the

Weight Cable (110). Tighten the Cable into the

Weight Tube (not shown) until the slack is

removed from the Cable. Retighten the M12 Nut

against the M12 Washer (33).

110

Do not overtighten the cables. If the cables are overtightened, the top weight will be lifted off the weight

stack. If a cable tends to slip off the pulleys often, it may have become twisted. Remove the cable and

re-install it. If the cables need to be replaced, see the part ordering information on the back cover of this manu-

al.

MAINTENANCE

EXERCISE GUIDELINES

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 mus-

cles will continually adapt and grow as you progres-

sively 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 three 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 mod-

erate percentage of their capacity. Select a moderate

amount of weight and increase the number of repeti-

tions in each set. Complete as many sets of 15 to 20

repetitions as possible without discomfort. Rest for one

minute after each set. Work your muscles by complet-

ing 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 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.

• Rest from both strength training and aerobic exercise

for at least one full day each week to give your body

time to regenerate.

The combination of strength training and aerobic exer-

cise will reshape and strengthen your body, plus devel-

op 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 overdo-

ing it during the first few months of your exercise pro-

gram. 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 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-

gram.

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,

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 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.

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 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. The

chart on page 31 of this manual can be photocopied

and used to schedule and record your workouts. 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 achiev-

ing the greatest results is to make exercise a regular

and enjoyable part of your everyday life.
