53. Insert the two Locking Pins (53) into the Butterfly

Frame (9). Attach the tether on the Pins to the

Butterfly Frame with a #8 x 3/4" Screw (68). Do

not fully tighten the Screw.

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

ADJUSTMENTS, starting on the following page.

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

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

the cables are not properly routed, they may he damaged when heavy weight is used. See the CABLE

DIAGRAM on pages 24 and 25 of this manual for proper cable routing. If there is any slack in the

cables, you will need to remove it by tightening the cables; see TIGHTENING THE CABLES on page

22.

ADJUSTMENTS

This section explains how to adjust the weight system. See the EXERCISE GUIDELINES on page 26 for impor-

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

exercise guide to see the correct form for each exemise.

Make sure all parts are properlytightened 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.

ATTACHING THE ACCESSORIES TO A PULLEY

STATION

Attach the Lat Bar (42) to the High Cable (45) with a

Cable Clip (52). For some exercises, the Chain (not

shown) should be attached between the Lat Bar and

the High Cable with two Cable Clips. Adjust the

length of the Chain between the I.at Bar and the

High Cable so the Lat Bar is in the correct start-

ing position for the exercise to be performed.

The Handle (not shown) and Ab Strap (not shown)

can be attached in the same manner. The acces-

sories can be attached to the Low Cable (not shown)

in the same manner.

CHANGING THE WEIGHT SETTING

To change the weight setting of the weight stack,

insert the Weight Pin (86) under the desired Weight

(72). Be sure to insert the Weight Pin until the bent

end of the Weight Pin is touching the Weights, and

tum the bent end downward. The weight setting of the

weight stack can be changed from 6 pounds to 106

pounds, in increments of 12.5 pounds. Note; Due to

the cables and pulleys, the actual amount of

resistance at each exercise station may vary from

the weight setting. Use the WEIGHT RESISTANCE

CHART on page 23 to find the actual amount of

resistance at each weight station.

CONVERTING THE BUTTERFLY ARMS

To use the Butterfly Arms (10, 11) as butterfly arms,

insert the Locking Pins (53) into the butterfly holes in

the Right Upright (6).

To use the Buttertly Arms (10, 11) as press arms,

insert the Locking Pins (53) into the press holes in the

Butterfly Frame (9).

Make sure that the Locking Pins (53) are fully

Inserted Into the same set of holes before pep

forming any exercises.

TIGHTENING THE CABLES

Woven cable, the type of cable used on the weight

system, can stretch slightlywhen it is firstused. If there

is slack in the cables before resistance is felt, the

cables should be tightened.

See drawing A. Slack can be removed by movingthe

3 1/2" Pulley (38) and Cable Trap (91) to a higher set

of holes in a Double "tY-Bracket (56). Remove the 3/6"

Nylon Locknut (70) and the 3/8" x 2" Bolt (62) from the

Cable Trap, the Pulley,and the Double "U"-Bracket.

Re-attach the Pulley and the Cable Trap to the new set

of holes in the Double "U"-Bracketwith the Bolt and

Locknut. Make sure that the Cable Trap is In the

proper position and that the Cable and Pulley

move smoothly.

Move the 3 1/2" Pulley (38) in the other Double "U"-

Bracket (56) in the same manner.

See drawing B. Slack can be removed by moving the

3 1/2" Pulley (38) and the Cable Trap (91) to the higher

set of holes in a "U"-Brecket (85). Remove the 3/8"

Nylon Locknut(70) and the 3/8" x 2" Bolt (62) from the

Cable Trap, the Pulley,and the =U"-Bracket. Re-attach

the Pulley and the Cable Trap to the higher set of holes

in the =U"-Bracket with the Bolt and Locknut. Make

sure that the Cable Trap is in the proper position

and that the Cable and Pulley move smoothly.

Move the 3 1/2" Pulley (38) in the other "U"-Bracket

(85) in the same manner.

See drawing B. Slack can also be removed from the

cables by tightening the 1/4" Nylon Locknuts(65)

attaching a cable to either "U"-Bracket (85), or the

Small "U"-Bracket (79). To do this, you may need to

remove the 3 1/2" Pulley (38) from the "U"-Bracket, or

remove the Small "U"-Bracket from the Weight Tube

(not shown). Make sure that the cables are not too

tight or the Top Weight (74) will be lifted off the weight

stack.

ADJUSTING THE LEG PRESS PLATE

To adjust the Leg Press Plate (31), remove the Leg

Press Pin (87) from the Leg Press Frame (30) and the

Adjustment Tube (88). Move the Tube to the desired

positionand secure it in place with the Pin. Be sure

the Pin is turned to the locked position around the

Leg Press Frame.

WEIGHT RESISTANCE CHART

The chart below shows the approximate weight resistance at each exercise station. "Top"refers to the 6Ib, 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 butterfly 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.

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 intensityof your exercise. You can

adjust the intensitylevel 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 dght

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 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 1

minute after each set. Work your muscles by complet-

ing more sets rather than by using high amounts of

weight.

Weight Lose

To lose weight, use alow 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 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 exemise

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 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 lightexercise to warm up. Warming up prepares

your body for more strenuous exercise by increasing

cimulation, raising your body temperature and deliver-

ing more oxygen to your muscles.

WORKING OUT

Each workout should include 6 to 10 different exemis-

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 dght 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 exemise, 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 exemises, and a list of the

muscles affected. Refer to the muscle chart on page

27 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, 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.
