the cables are not properly routed, they may be 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.

53. Insert the two Locking Pins (53) into the Butterfly Frame (9). Attach the tether on the Pins to the Butterfly Frame with an M4 x 9.5mm Self-tapping Screw (68). Do not fully tighten the Screw.

Page 21

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

Make sure all parts are properly tightened each time the weight system is used. Replace any worn parts immediately . 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 Lat Bar and the High Cable so the Lat Bar is in the correct starting position for the exercise to be performed.

The Handle (not shown) and Ab Strap (not shown) can be attached in the same manner. The accessories can be attached to the Low Cable (not shown) in the same manner.

ADJUSTMENTS

CHANGING THE WEIGHT SETTING

T o 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 turn 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

T o use the Butterfly Arms (10, 1 1) as butterfly arms, insert the Locking Pins (53) into the butterfly holes in the Right Upright (6).

T o use the Butterfly Arms (10, 1 1) 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 performing any exercises.

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.

See drawing A. Slack can be removed by moving the 90mm Pulley (38) and Cable Trap (91) to a higher set of holes in a Double “U”-Bracket (56). Remove the M10 Nylon Locknut (70) and the M10 x 50mm 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”-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 90mm Pulley (38) in the other Double “U”-Bracket (56) in the same manner.

See drawing B. Slack can be removed by moving the

90mm Pulley (38) and the Cable Trap (91) to the higher set of holes in a “U”-Bracket (85). Remove the M10 Nylon Locknut (70) and the M10 x 50mm 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 90mm 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 M8 Nylon Locknuts (71) attaching a cable to either “U”-Bracket (85), or the Small “U”-Bracket (79). T o do this, you may need to remove the 90mm 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 T op Weight (74) will be lifted off the weight stack.

ADJUSTING THE LEG PRESS PLATE

T o 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 position and 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 6 lb. top weight. The other numbers refer to the 12.5 lb. weight plates. Weight resistance shown for the butterfly arm station 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

T o 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 performed. (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

T o 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, plus 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. T o 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 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.

Page 27

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 workout.

• 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.
