Getting Started
As you get to know your new Precor Elliptical Fitness
Crosstrainer® and your own fitness goals, you’ll use the
advanced features of the equipment more often. To
begin with, though, here’s an easy way to start out.
6. Use the up and down arrows to adjust the amount
of resistance. If the equipment includes a
motorized CrossRamp® adjustment, use the
arrows on the left to adjust the CrossRamp height,
and the arrows on the right for the resistance.
Note: These instructions assume that your equipment
has been completely installed and set up (refer to
Setting Up Your Equipment).
WARNING
Read through ALL of the safety
information in this manual before you
use the equipment.
To get started with your new Elliptical Fitness
Crosstrainer:
1. Turn the equipment on if necessary.
2. If the locking pin is engaged, release it.
3. Hold one handrail and step onto the pedals.
4. Grasp the handlebars securely.
5. Press the GO key.

Figure 6: CrossRamp and resistance adjustments
7. If you need to end your workout early, press
RESET.
Note: A thin protective sheath covers the roller arm
wheels on your EFX. As you exercise, the roller arms
move up and down the ramp and the wheels tend to
squeak until the protective sheath wears off. Any noise
from the wheels is normal and will stop after a break-in
period. Please allow a break-in period of approximately
ten hours before calling Customer Support.
Using CrossRamp
CrossRamp is a Precor technology that helps you get
more out of your EFX. As you select different
CrossRamp settings, the angle of the roller ramp
changes while your body remains in a biometrically
correct position. In addition to increasing the intensity
of your workout, higher CrossRamp settings change
the motion of your feet and legs, bringing additional
focus to your quadriceps and gluteal muscles. The
following two figures show how the different
CrossRamp settings target different muscle groups in
your lower body.
Note: On 400-series EFX models, the CrossRamp
range is available as a larger number of smaller level
changes than those available on 200-series models.
Getting Started

The following figures show the differences between
the level settings on these different EFX models.
Figure 8: Muscle groups targeted by CrossRamp (200series EFX models)
Figure 7: Muscle groups targeted by CrossRamp (400series EFX models)
Be sure to try different CrossRamp settings during your
workout. In addition to exercising different groups of
muscles, you may also find that certain settings adjust
the performance of the EFX to your height and body
geometry.
Note: If your EFX is equipped with movable arms,
using them also exercises muscle groups in your arms
and chest. Note also that 200-series EFX models
provide a more limited range of CrossRamp levels.

Once you have created both user profiles, you can
switch back and forth between them by pressing the
two USER keys.
24
To create a user profile:
1. Press one of the two USER keys.
2. Use the left and right arrow keys to adjust the
workout length you want, then press ENTER.
3. Adjust the weight shown so that it matches your
weight, then press ENTER again.
4. Adjust the age shown so that it matches your age,
then press ENTER to save your changes.
Note: To change a user profile after it has been set up,
press the USER key for that profile and hold it for three
seconds.
Measuring Your
Heart Rate
Important: The heart rate and SmartRate® features are
intended for reference only. They may not be accurate for
every user or at every intensity and are not intended for
use as a medical device. Also visit:
www.precor.com/en-us/customer-service/faq.
Precor cannot guarantee the accuracy of any readings
you may get, but for best results, measure your heart
rate in one of two ways:


If you have a chest strap (for use with a fitness
watch, for example), the equipment can receive
the heart rate signal the strap transmits.
No te: You may have better results using a chest
transmitter strap.
You can grasp the heart rate sensors on the
handlebars.
Measuring Your Heart Rate
When the equipment detects your heart rate, the
following things happen:
The heartbeat indicator (icon) appears over the
SmartRate scale (refer to Using SmartRate).
 After a few seconds, the console displays your
current heart rate.
Before you start working out, make sure you know your
maximum heart rate. Then, as you work out, be sure to
reduce the intensity of your exercise if you reach or
exceed that number.

CAUTION: Your heart rate should never exceed 85% of
your maximum aerobic heart rate.
You can use the following formula, provided by the
American College of Sports Medicine®, to figure out
your maximum heart rate:
Maximum heart rate = 207 – (your age × 0.67)
Your typical target heart rate is 70% of your maximum
rate.
25
Precision Series / Energy Series Elliptical Fitness Crosstrainer Owner's Manual: EFX 425 / 423 / 225 / 222 / 221
The following graph shows how your effective heart
rate ranges vary with your age.
Figure 13: Heart rate target zones
26
On the Workout List, you can find several
preprogrammed heart rate workouts. These workout
courses automatically manage your heart rate at a
target level based on your age. By monitoring your
heart rate and making changes to the equipment’s
settings as you exercise, the workouts keep your heart
rate within a few beats per minute of the target rate.
Using SmartRate
SmartRate displays actual heart rate information in
relation to the user’s target zone for weight loss and
cardiovascular training.
Note: Precor cannot guarantee the accuracy of any
readings you receive.
The SmartRate monitor is visible during all workouts.
In addition, Heart Rate Control (HRC) workouts adjust
their intensity automatically to keep a user’s heart rate
in its target zone.
CAUTION: Your heart rate should never exceed 85% of
your maximum heart rate. You can calculate your
maximum heart rate using the following formula:
Maximum heart rate = 207 – (0.67 × your age)
CAUTION: Before beginning any fitness program, see your
physician for a thorough physical examination. Seek
advice from your physician to learn the target heart rate
appropriate for your fitness level.
Measuring Your Heart Rate
To test your heart rate:
1. Select a workout and press GO or ENTER.
2. Grasp the heart rate sensors with both hands. A
blinking heart indicator appears while the
equipment reads your heart rate. After a few
seconds, the console displays your heart rate in
beats per minute and shows it on the SmartRate
scale. The labels next to the SmartRate scale
indicate the zone where your heart rate is currently
operating:
– Warm Up
– Fat Burn (weight loss)
– Cardio
– High
Note: In the Basic Heart Rate Control workout, the GO
key is deactivated. The equipment needs to know your
age to set an accurate target heart rate, so you must
either enter it or select a user account before you start
the Basic Heart Rate Control workout.
27
Precision Series / Energy Series Elliptical Fitness Crosstrainer Owner's Manual: EFX 425 / 423 / 225 / 222 / 221
28
Getting Accurate Heart Rate
Readings
Note: To receive an accurate reading, the strap needs
to be in direct contact with the skin on the lower
sternum (just below the bust line for women).
Precor cannot guarantee the accuracy of any readings
you may get, but for best results, heart rate sensors
need to be securely in contact with your skin. Use the
following guidelines to make sure they are.
1.
Note: You may have better results using a chest
transmitter strap.
Carefully dampen the back of the strap with tap
water. Refer to the following figure.
Note: Do not use deionized water. It does not have
the proper minerals and salts to conduct electrical
impulses.
To attach a chest strap:
WARNING
Signals used by the chest strap
transmitter (or heart rate strap) may
interfere with pacemakers or other
implanted devices. Contact your
doctor, the manufacturer of the chest
strap, and the manufacturer of the
implanted device before using a chest
strap transmitter.
Important: Precor cardio equipment works with 5 KHz
chest straps only. It does not work with Bluetooth®-based
chest straps, which are designed for use with mobile apps.
Figure 14: Moisten chest strap
2. Adjust the strap and fasten it around your chest.
The strap should feel snug, not restrictive. Refer to
the following figure.
Figure 15: Adjust chest strap
3. Make sure that the chest strap is right side up, lies
horizontally across your chest, and is centered in
the middle of your chest. Refer to the following
figure.
4. After you put on the chest strap, face the display
console for a few seconds. This allows the receiver
in the console to recognize the signal from the
chest strap.
If you use the touch-sensitive grips, be sure to grasp
them securely (but not tightly—use a loose, cupping
hold) on both sides. You may need to wait for 15 to 20
seconds before your heart rate is displayed.
Important: The touch-sensitive grips work well for most
people. However, because of their body chemistry or
erratic heartbeats, a few people cannot use the grips. If this
applies to you, a chest strap may provide better results.
However, do not grasp the touch-sensitive grips while
wearing a chest strap—using both at the same time can
cause erratic heart rate readings.

Troubleshooting Heart Rate
Readings
Precor cannot guarantee the accuracy of any readings
but if your heart rate readings look wrong, or if you do
not see any readings at all, check the following list for
possible causes. If the solutions in this list do not solve
the problem, contact your dealer or Precor Customer
Support.
Important: The heart rate and SmartRate® features are
intended for reference only. They may not be accurate for
every user or at every speed and are not intended for use
as a medical device. Holding the heart rate handle touch
sensor while running may also decrease accuracy of the
heart rate reading and is not recommended. Also visit:
www.precor.com/en-us/customer-service/faq.
30
No Heartbeat Icon or Heart Rate Display
Precor cannot guarantee the accuracy of any readings
you may get, but for best results, follow these tips.
The heart rate sensors may not be in secure contact
with your skin. Try the following solutions.
For touch-sensitive grips:



Make sure that your hands grasp the touchsensitive grips continuously and firmly (but not
tightly) for at least five to ten seconds.
Check that the palms of your hands are not
covered with any sort of salve, rub, or lotion. If they
are, wash them.
Check that your hands are not too dry. If they are,
moisten them slightly.
For a chest strap:


Make sure the strap is fastened, positioned, and
moistened correctly.
Make sure the strap is compatible with the
equipment. It must be a 5 kHz strap. Heart rate
straps that function at other frequencies, and
Bluetooth-based straps, are not compatible with
this equipment.
Measuring Your Heart Rate
The Displayed Heart Rate Is Wrong Or
SmartRate Doesn’t Work
Precor cannot guarantee the accuracy of any readings
you may get, but for best results, follow these tips.
The touch-sensitive grips may not be making secure
contact. Try the following solutions:
Make sure that your hands are clean, slightly
moist, and positioned as described earlier in this
table.
 Try using a chest strap instead of the grips.
If you are trying to use the grips and an active chest
strap at the same time, choose one or the other. Either
do not grasp the touch-sensitive grips, or remove or
turn off the chest strap.

Choosing and
Completing a
Workout
The instructions shown earlier in this manual provide
the simplest possible steps for getting started with
your new fitness equipment. But in most cases, you’ll
want to start with one of the preprogrammed workouts
available on the equipment.
32
Choosing a Workout
Your fitness equipment has been programmed with a
library of workout plans to help you meet your fitness
goals.
To choose a workout:
1. Press the WORKOUTS key repeatedly to scroll
through the available workouts.
2. When you reach the workout you want, press the
ENTER key to select it, then press GO to begin.
Tip: The WORKOUTS key remains active while you
work out, in case you want to switch workouts in the
middle of your exercise session
.
To adjust the duration of your workout and your
personal information:
1. At any time during your workout, press ENTER.
2. Use the left and right arrow keys to adjust the
duration of the workout, then press ENTER to
continue.
3. Adjust the weight shown so that it matches your
weight, then press ENTER again.
4. Adjust the age shown so that it matches your age,
then press ENTER one last time.
Available Workouts
Your fitness equipment includes a wide selection of
workouts that are carefully designed to make sure you
get the best results out of every workout.
The human body is extremely efficient. If it makes the
same motion regularly over many days or weeks, it
learns to make that motion with less and less effort.
This process, called muscle adaptation, has one
drawback—the longer you stick to the same workout,
the less good that workout does you.
To prevent muscle adaptation from setting in as you
work out, try different kinds of workouts on different
days. By keeping your muscles guessing, you’ll keep
your energy use up, promoting faster weight loss and
better conditioning.
In the following figures, the elevated areas show the
training profile for each preset workout.
Choosing and Completing a Workout
33
Precision Series / Energy Series Elliptical Fitness Crosstrainer Owner's Manual: EFX 425 / 423 / 225 / 222 / 221
Interval 1-1 and Interval 1-2
Interval workouts help exercisers improve strength,
endurance, aerobic and anaerobic fitness. They
alternate short bursts of high intensity activity with
recovery periods.
These workouts are designed to raise and lower your
heart rate in a repeating fashion for a user-defined
period of time by alternating rest and work intervals of
two minutes each (for the Interval 1-1 workout) and
two minutes of rest followed by four minutes of work
(for the Interval 1-2 workout).
34
Training tip: You can further tailor your rest and work
period intensity by adjusting the resistance,
CrossRamp setting, or both at any time. The
equipment remembers these preferences for each
upcoming interval.
Figure 17: Interval 1-1
Figure 18: 1-2 Interval
Weight Loss
The American College of Sports Medicine
recommends that adults get at least 30-60 minutes of
moderately intense exercise five days a week. The
Weight Loss workout provides a structured and timebased aerobic challenge designed to help you reverse
or prevent weight gain.
The total time for this workout is fixed at 28 minutes. It
consists of alternating four-minute work and rest
intervals. During the work intervals, you can change
the resistance at any time.
Training tip: For best results, wear a heart rate
monitor and maintain a target heart rate that is
between 50% and 70% of your maximum heart rate.

Basic Heart Rate Control
This workout monitors your heart rate to guide you
through a moderate intensity program that is optimal
for aerobic conditioning.
During the workout, your target heart rate is based on
the following calculation:
Target heart rate = 70% × (207 – (0.67 × your age))
The equipment adjusts resistance, CrossRamp level, or
both to maintain your target heart rate while you work
out.
Figure 20: Basic HRC
When a heart rate signal is not received, a heart shape
with a question mark appears in the upper text display.
Recheck your hand grip on the handheld sensors or the
placement of your chest strap.
Note: For the unit to detect your heart rate, you must
grip the handheld heart rate sensors or wear a chest
strap while exercising. In the presence of both
handheld and wireless data, the handheld data takes
precedence and is displayed.
Training tip: This program offers a coaching benefit
for new and returning users who are learning how to
maintain a moderate, steady exertion level throughout
their workouts.
Hill Climb
This workout engages a wider range of muscle groups
by adjusting the resistance and CrossRamp settings to
simulate a hill climbing experience.
For improved conditioning of your thigh and calf
muscles, the workout requires you to reverse direction
after 25%, 50%, and 75% of the total time. At these
points, you will see text messages on the console that
prompt you to change direction. Increasing or
decreasing one workout segment increases or
decreases all remaining segments by the same
amount.
Training tip: Incorporating hill climb workouts into
your regular cardio schedule will keep your workouts
varied and help build lower body muscle strength.
Figure 21: Hill Climb
Note: If the equipment has a manually operated ramp,
we recommend adjusting it to the highest possible
setting before you begin.

Cross Country
Aerobic
This workout delivers true training variety and
muscular engagement by continuously adjusting the
incline to simulate the dynamic terrain of an outdoor
run. Any increase or decrease made in one workout
segment will increase or decrease all remaining “hills”
and “valleys” depicted on the display by the same
amount.
This workout is designed to condition your heart. After
an accelerating warmup stage, the equipment reminds
you to maintain a constant pace while it increases the
CrossRamp setting steadily. At the end of each cycle,
the CrossRamp setting returns to its lowest value and
starts to increase again.
For improved conditioning of your thigh and calf
muscles, the workout requires you to reverse direction
after 25%, 50%, and 75% of the total time. At these
points, you will see text messages on the console that
prompt you to change direction.
Training tip: Advanced users can take their hands off
the handlebars to make better use of their core
stabilizer muscles throughout the workout.
Figure 22: Cross Country
You can modify the CrossRamp setting for each twominute segment, and you can change the resistance at
any time.
Note: You cannot switch to or from the Aerobic
workout during your exercise session.
Gluteal
Crosstrainer
Strong glutes contribute to better posture, improved
spine and hip stabilization, and reduction in lower body
injuries at the hips, knees and ankles. This workout
targets your thighs and glutes as it gradually increases
in intensity. For maximum effect, the workout requires
you to reverse direction after 25%, 50%, and 75% of
the total time. At these points, you will see text
messages on the console that prompt you to change
direction.
This workout targets your thigh and calf muscles as it
moves you through a gradual climb and decline. It
requires you to reverse direction after 25%, 50%, and
75% of the total time. At these points, you will see text
messages on the console that prompt you to change
direction.
You can modify either the CrossRamp level or the
resistance level at any time during this workout. If the
equipment has a manually operated ramp, we
recommend adjusting it to the highest possible setting
before you begin.
Training tip: To increase your core activation
throughout this workout, take your hands off the

Maintenance
Inspection
It is important to perform the minor maintenance tasks
described in this section. Failure to maintain the
equipment as described here could void the Precor
Limited Warranty.
Look and listen for loose fasteners, unusual noises,
worn or frayed power cords, and any other indications
that the equipment may be in need of service. If you
notice any of these, obtain service.
DANGER
To reduce the risk of electrical shock,
always unplug the equipment from its
power source before cleaning it or
performing any maintenance tasks.
Inspect the EFX before use.
Important: If you determine that the EFX needs service,
make sure that the EFX cannot be used inadvertently. Turn
the unit Off, insert the locking pin and then unplug the
power cord from its power source. Make sure other users
know that the EFX needs service.
To order parts or to contact a Precor authorized
service provider in your area, refer to Obtaining Service.
Cleaning the Equipment
Storing the Chest Strap
Most of the working mechanisms are protected inside
the covers. However, for efficient operation, the EFX
relies on low friction. To keep the friction low, the
unit’s rollers, ramp, foot pedals, handlebars, and covers
must be as clean as possible.
Store your chest strap in a place where it remains free
of dust, dirt, and moisture, such as in a closet or
drawer. Be sure to protect the chest strap from
extremes in temperature. Do not store it in a place that
may be exposed to temperatures below 32° F (0° C).
Precor recommends the EFX be cleaned before and
after each workout to remove dust, dirt, water, and
sweat. Use mild soap and water to dampen a soft cloth
and wipe all exposed surfaces.
To clean the chest strap, use a sponge or soft cloth
dampened in mild soap and water. Dry the surface
thoroughly with a clean towel.
CAUTION: Do not use any acidic cleaners. Doing so will
weaken the paint or powder coatings and void the Precor
Limited Warranty. Never pour water or spray liquids on
any part of the EFX, and remove any accumulated sweat
from the EFX after use. Allow the EFX to dry completely
before using it again.
Frequently vacuum the floor around the unit to prevent
the accumulation of dust and dirt, which can affect the
smooth operation of the unit. Use a soft nylon scrub
brush to clean the foot pedals.
Maintenance
Long-Term Storage
When the equipment is not in use for any length of
time, turn it off. Make sure that the power cord is
unplugged from its power source and is positioned so
that it will not become damaged or interfere with
people, furniture, or other equipment.

CAUTION: You will need assistance to assemble this unit. DO NOT attempt assembly
by yourself.
Follow these installation requirements when assembling the unit:






Assemble the EFX near the location where you plan to use it and provide
ample space around the unit.
Important: Consult your owner’s manual for proper placement of your equipment.
Assemble the EFX on a solid, flat surface. A smooth, flat surface under the
EFX helps keep it level, and a level EFX will have fewer malfunctions.
Open the box and assemble the components in the sequence presented in this
guide. If you plan to move the unit, obtain help and use proper lifting
techniques.
Do not grasp any plastic part while lifting or moving the unit. The plastic parts
are not reinforced and they may break.
Obtain assistance. Ask another capable adult for assistance during the
assembly process.
