ASSEMBLY  
As you assemble the weight system, 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 system can be assembled suc-  
cessfully by anyone. However, it is important to  
realize that the versatile weight system has  
many parts and that the assembly process will  
take time. Most people find that by setting aside  
plenty of time, assembly will go smoothly.  
• For help identifying small parts, use the PART  
IDENTIFICATION CHART.  
An Allen wrench (included) and 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.

ADJUSTMENTS, starting 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 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.

TIGHTENING THE CABLES  
A
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.  
56  
See drawing A. Slack can be removed by moving the  
3 1/2” Pulley (38) and Cable Trap (91) to a higher set  
of holes in a Double “U”-Bracket (56). Remove the 3/8”  
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”-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.

EXERCISE GUIDELINES  
THE FOUR BASIC TYPES OF WORKOUTS  
PERSONALIZING YOUR EXERCISE PROGRAM  
Muscle Building  
To increase the size and strength of your muscles,

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.)

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  
The proper amount of weight for each exercise  
depends upon the individual user. You must gauge  
Begin each workout with 5 to 10 minutes of stretching  
your limits and select the amount of weight that is right and light exercise to warm up. Warming up prepares  
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.

circulation, raising your body temperature and deliver-  
ing more oxygen to your muscles.  
WORKING OUT  
Toning  
You can tone your muscles by pushing them to a mod- Each workout should include 6 to 10 different exercis-  
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.  
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.  
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.  
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  
Cross Training  
Cross training is an efficient way to get a complete and moving only the appropriate parts of the body.  
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 exercise  
for at least one full day each week to give your body  
time to regenerate.  
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. Refer to the muscle chart on page  
27 to find the names of the muscles.
