Note: This introduction will save you more time
than it takes to read it!
Identifying Parts
To help you identify the small parts used in assembly, we have included a PART IDENTIFICATION
CHART located in the center of this manual. Place
the chart on the floor or work table and use it to
quickly identify different parts for each step. Note:
Some small parts may have been pre-attached for
shipping. If a part is not in the parts bag, check to
see if it has been pre-attached.
Orienting Parts
As you assemble this product, be sure that all parts
are oriented as shown in the drawings.
Tightening Parts
Tighten all parts as you assemble them, unless
instructed to do otherwise.
Lining Up the Tools
Assembly requires the following tools (not included):
• Two (2) adjustable wrenches
• One (1) standard screwdriver
• One (1) phillips screwdriver
• One (1) rubber mallet
• Lubricant, such as grease or petroleum jelly,
and soapy water
• Tape, such as clear tape or masking tape
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.
Some assembly steps require two people.
Giving Yourself a Good Start
Before you begin the assembly process itself, take
the time to complete the steps outlined here.
Clearing the Workspace
Clear a workspace that is large enough to hold all
parts and allow you to walk all the way around the
assembled equipment.
Unpacking the Box
To make the assembly process as smooth as possible, we have broken it into separate stages. All parts
used in each stage are found in individual packages
in the shipping box. Place all parts in a cleared area
and remove the packing materials. Do not dispose of
the packing materials until assembly is completed.
Important: Wait until you begin each assembly
stage to open the parts bag labeled for that
assembly stage.
Assembly
Making Things Easier for Yourself
Everything in this manual is designed to ensure
that our products can be assembled successfully
by anyone. However, it is important to realize
that your new equipment is a sophisticated product with many small parts. The assembly process
will take time—possibly several hours. Most people find that by setting aside plenty of time, and
by deciding to make the task enjoyable, assembly will go smoothly. You may want to complete
the process over a couple of evenings.
The Four Stages of the Assembly Process
Frame Assembly
You will begin by assembling the base and the
upright frames that serve as the skeleton of the
equipment.
Arm Assembly
This assembly completes the press and butterfly
arms that you operate while you are exercising.
Cable Assembly
This assembly completes the cables and pulleys
that connect the moving arms with each other and
with the weights.
Seat Assembly
This assembly completes the seat and backrest
that support your body while you are exercising.

ADJUSTMENT, beginning on page 21 of this manual.
Before using the home gym, 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. If there is any
slack in the cables, you will need to remove the slack by tightening the cables. See TROUBLESHOOTING AND MAINTENANCE on page 22.

Cable Diagrams
The Cable Diagrams below and on the next page show the proper routing of the Short Cable (71), the Medium
Cable (72), and the Long Cable (73). The numbers show the correct route for each Cable. Make sure that the
Cables are routed correctly, that the Pulleys move smoothly, and that the Cable Traps do not touch or
bind the Cables. Incorrect cable routing can damage the home gym.

Using the Curl Pad
To use the Curl Pad (69), insert the Curl Post (70) into the
Seat Brace (75) and secure the Curl Post at the desired
height with the Adjustment Knob (45).
Attaching the Lat Bar or Nylon Strap to the High
Pulley Station
Attach the Lat Bar (50) to the Medium Cable (72) with a
Cable Clip (57). For some exercises, the Chain (55)
should be attached between the Lat Bar and the Medium
Cable with two Cable Clips. Adjust the length of the
Chain between the Lat Bar and the Medium Cable so
the Lat Bar is in the correct starting position for the
exercise to be performed.
The Nylon Strap (56) can be attached in the same manner.
Attaching the Lat Bar or Nylon Strap to the Low
Pulley Station
Attach the Lat Bar (50) to the Long Cable (73) with a
Cable Clip (57). For some exercises, the Chain (55)
should be attached between the Lat Bar and the Long
Cable with two Cable Clips. Adjust the length of the
Chain between the Lat Bar and the Long Pulley Cable
so the Lat Bar is in the correct starting position for
the exercise to be performed.
The Nylon Strap (56) can be attached in the same manner.
Adjustment
Changing the Weight Setting
To change the setting of the weight stack, insert a Weight
Pin (87) under the desired Weight (8). Make sure you
insert the Weight Pin as far as it will go. 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 23 to
find the approximate amount of resistance at each
weight station.
The instructions below describe how each part of the home gym can be adjusted. Refer to the exercise poster
accompanying this manual to see how the home gym should be set up for each exercise. IMPORTANT: When
using an attachment, make sure it is in the correct starting position for the exercise to be performed. If
there is any slack in the cables or chain as an exercise is performed, the effectiveness of the exercise
will be reduced.

Slack can be removed from the Long Cable (73) by moving the 3 1/2” Pulley (5) on the Long Cable in the direction shown. It is attached to the small tube on the Press
Seat Frame (52). There are two free holes in the small
tube, and you can move the 3 1/2” Pulley to any one of
them to tighten the cables. To do this, remove the 3/8”
Nylon Locknut (4), 3/8” Flat Washer (17), and the 3/8” x
2 1/2” Bolt (6). Start by moving the 3 1/2” Pulley one
hole, and then one more as needed.
Reattach the Bolt, Washer, and Locknut.
Trouble-shooting and Maintenance
Inspect and tighten all parts each time you use the home gym. Replace any worn parts immediately. The
home gym can be cleaned using a damp cloth and mild non-abrasive detergent. Do not use solvents.
Tightening the Cables
If a cable slips off the pulleys often, the cable 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.
The type of cable used on the home gym 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 different ways:
The Adjustable Pulley Plates (44) have two sets of
adjustment holes. By moving one or both 3 1/2” Pulleys
(5) to a different set of holes, you will tighten the cables.
To move a 3 1/2” Pulley (5), remove the 3/8” Nylon
Locknut (4) and the 3/8”x 2” Bolt (35). Remove the Cable
Trap (39) and Pulley from the Adjustable Pulley Plates
(44). Re-attach the Pulley and Cable Trap to the appropriate adjustment hole in the Pulley Plates. Note: Begin
by moving one Pulley to the second adjustment hole.
If additional adjustment is needed, move the other
Pulley until the cables are tight.

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. 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.
Weight Resistance Chart
The threaded shaft on the Medium Cable (72) attached to
the Weights (8) can also be used to tighten the cables.
To tighten the Medium Cable (72), remove the Small “U”Bracket (43) by removing the 5/16” Nylon Locknut (2) and
the 5/16” x 1 3/4” Bolt (9).
See the inset drawing. Tighten the 1/4” Nylon Locknut
(16) at the end of the Medium Cable (72) as far as it will
go. Then re-attach the Small “U”-Bracket (43).
