ADJUSTMENTS

This section explains how to adjust the weight bench. See the EXERCISE GUIDELINES on page 24 for important information about how to get the most benefit from your exercise program. See the accompanying exercise guide to see the correct form for each exercise.

Make sure all parts are properly tightened each time the weight bench is used. Replace any worn parts immediately. The weight bench can be cleaned with a damp cloth and a mild, non-abrasive detergent. Do not use solvents.

ADJUSTING THE BACKREST

To adjust the position of the Backrest (14), hold the upper end of the Backrest with one hand and lift the
Adjustment Lever (11) with the other hand, disengaging the Backrest Bracket (7). Raise or lower the
Backrest to the desired position. Lower the Adjustment Lever so that the M10 x 62mm Flat Head Screw
(27 [not shown]) engages one of the notches in the Backrest Bracket.

WARNING: Always hold the Backrest (14) securely before disengaging the Backrest Bracket (7). Always make sure the Backrest Bracket is fully engaged before using the Backrest.

ATTACHING THE CURL POST

For some exercises, the Curl Post (6) must be attached to the weight bench. Slide the Curl Post into the Leg Lever Bracket (5). Align the adjustment holes in the Curl Post with the adjustment hole in the Leg
Lever Bracket. Tighten the Curl Knob (29) into the adjustment hole in the Leg Lever Bracket. Fully tighten the Knob.

Bar (76) with a 1/4” x 9.5mm Allen Head Set Screw (120). Make sure that the Set Screw is in the bottom
of the Adapter. Attach the other Weight Adapter to the Curl Bar in the same manner.

ADDING WEIGHTS TO THE LEG LEVER

To use the Leg Lever (4), slide the desired weights (not included) onto the Weight Tube (25). Secure the weights with a Weight Clip (58 or 77 [not shown]). Weights can be added to the Curl Bar (not shown) in
the same manner. Secure the weights to the Curl Bar with two Weight Clips (53 or 77 [not shown]).

ATTACHING THE ACCESSORIES

To use the Lat Bar (57), attach it to the Lat Cable (81) with a Cable Clip (122). For some exercises, the
Chain (78) should be attached between the Lat Bar and the Lat Cable with two Cable Clips. Adjust the
length of the Chain between the Lat Bar and the Cable so that the Lat Bar is in the correct starting position for the exercise to be performed. The Ankle Strap (not shown) can be attached to the Low Cable (not shown) in the same manner.

ADDING WEIGHTS TO THE BARBELL OR THE WEIGHT CARRIAGE

To use the barbell or Weight Carriage (71), slide the desired amount of weight (not included) onto the Barbell Adapters (59) or Weight Carriage. Secure the weights with the Large Weight Clips (77).

USING THE LOCKING BAR

Before starting an exercise, position the Locking Bar (56) in the correct position for the exercise. To do this, stand in front of the rack and grip the Locking Bar (56) with both hands. Turn the Locking Bar until the two hooks disengage the slots in the Left and Right upright (36 [not shown], 69). Raise or lower the Locking Bar to a new position and turn it until the hooks engage the slots in the Uprights.

MOVING THE SAFETY SPOTTERS

Before starting an exercise, position the Safety Spotters (52) in the correct position for the exercise. To move the Safety Spotters (52) to a new position, grip the handles on the Spotter Hooks (53, 54 [not shown]) and pull the hooks out of the slots in the Uprights (36 [not shown], 69). Raise or lower the Safety Spotters to new positions and pivot the hooks back into the slots in the Uprights. (Always start an
exercise with the Safety Spotters positioned at the lowest point to which you want the barbell to move during the exercise.)

CABLE DIAGRAMS

The cable diagrams below show the proper routing of the Lat Cable (81), the Low Cable (82), and the Butterfly Cable (83). 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.

TROUBLESHOOTING

Make sure all parts are properly tightened each time the weight bench is used. Replace any worn parts immediately. The weight bench can be cleaned using a damp cloth and mild non-abrasive detergent. Do not use solvents.

TIGHTENING THE CABLES

Woven cable, the type of cable used on the weight bench, can stretch slightly when it is first used. If there is slack in the cables before resistance is felt, the cables should be tightened. Slack can be removed from the cables in several ways:

See drawing 1. To tighten the cables, remove the M10 Nylon Locknut (97) and the M10 x 45mm Bolt (112) from the lower 90mm Pulley (90), Cable Trap (125), and Pulley Plates (72). Reattach the Pulley
and the Cable Trap between a set of holes closer to the center of the Pulley Plates with the Bolt and Locknut. Make sure the Cable Trap is oriented to hold the Low Cable (82) in the groove of the Pulley.

See drawing 2. Additional slack can be removed from the cables by tightening a cable into the M6 Nylon Locknut (124) inside a Cable End Clip (85). To do this, pull the Clip Cover (84) back and use pliers to tighten the Locknut. Replace the Cover.

Do not over-tighten the cables. If a cable slips off the pulleys repeatedly, it may have become twisted. Remove the cable and re-install it. If the cables need to be replaced, see ORDERING REPLACEMENT PARTS on the back cover of this manual.

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 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 resistance 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 resistance for each exercise depends upon the individual user. You must gauge
your limits and select the amount of resistance 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 resistance.

TONING
You can tone your muscles by pushing them to a moderate percentage of their capacity. Select a moderate amount of resistance 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 resistance.

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.

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 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 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 the 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 accompanying 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 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. The chart on pages 26 and 27 of this manual can be photocopied and used to schedule and record your workouts. List the date, the exercises performed, the resistance used, and the number 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.
