If you are a beginner, start a cardio-conditioning

program to slowly adjust your body to a comfortable

level of exercise. Over a recommended 8-week

period, you will increase your endurance and strength

while improving flexibility.

If you have been exercising and feel that you have

reached an intermediate or advanced fitness level, you

probably have established goals for yourself.

For all fitness levels, plan to exercise at a comfortable

pace for 20 to 30 minutes a day. Wear a chest strap

to monitor your heart rate. Supplement your plans

with fitness workouts from the Precor web site

(www.precor.com). The Precor web site also provides

expert advice to help you reach your fitness goals.

Monitor Your Heart Rate

The SmartRate and heart rate displays provide visual

cues that help you adjust your fitness routine to reach

your goals. Use these features to keep your heart rate

within the target zones.

Wear a Chest Strap

During a workout, the heart rate features appear on

the display when you wear a chest strap. To receive

an accurate reading, the chest strap needs to be in

direct contact with your skin. After you put on the

chest strap, face the display console for a minimum of

15 seconds. This allows the receiver in the console to

recognize the signal from the chest strap.

1. Carefully dampen the back of the strap with tap

water (Diagram A).

Important: Do not use deionized water. It does

not have the proper minerals and salts to conduct

electrical impulses.

When these steps are complete, you are ready to view

your heart rate!

Touch-Sensitive Handrail Grips

Several Precor products incorporate touch-sensitive

heart rate grips on the handrails. If you prefer to use

the touch-sensitive handrail grips, use both hands.

Make sure both hands are moist (not dry) when you

grasp the touch-sensitive handrail grips.

SmartRate® Features

When you begin an exercise session, a blinking

segment in the SmartRate display appears if you

entered your age during the setup phase. The blinking

segment indicates the current zone of your heart rate.

The calculation used for the heart rate target zone is

your maximum aerobic heart rate:

(220 minus your age) multiplied by a percent.

For the ideal weight loss range, your heart rate should

remain between 55% and 70% of your maximum

aerobic heart rate. To improve your overall

cardiovascular and respiratory fitness level, maintain

your heart rate between 70% and 85% of your

maximum aerobic heart rate.

Make sure both hands are moist (not dry) and avoid
grasping the sensors too tightly.

Note: For the best heart rate monitoring results, wear a
chest strap.

sMARTRATE® FEATUREs

When you begin an exercise session, a blinking
segment in the SmartRate display appears if you
entered your age during the setup phase. The blinking
segment indicates the current zone of your heart rate.

The calculation used for the heart rate target zone is
your maximum aerobic heart rate:
207 - (age x 0.67), multiplied by a percentage.

For the ideal weight loss range, your heart rate should
remain between 55% and 69% of your maximum

aerobic heart rate. To improve your overall
cardiovascular and respiratory tness level, maintain
your heart rate between 70% and 85% of your
maximum aerobic heart rate. For the greatest benets,
maintain your heart rate in either zone for 30 minutes or
more at least three times a week.

7. If you need to end your workout early, press Reset.

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.
The following figures show the differences between
the level settings on these different EFX models.

Precision Series / Energy Series Elliptical Fitness Crosstrainer Owner's Manual: EFX 425 / 423 / 225 / 222 / 221 14

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.

Measuring Your Heart Rate

Precor cardio equipment can 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.

 You can grasp the heart rate sensors on the

handlebars.

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
your maximum heart rate:

Maximum heart rate = 207 – (your age × 0.67)

Your typical target heart rate is 70% of your maximum
rate.

Measuring Your Heart Rate

27

Precision Series / Energy Series Elliptical Fitness Crosstrainer Owner's Manual: EFX 425 / 423 / 225 / 222 / 221 28

The following graph shows how your effective heart
rate ranges vary with your age.

Figure 13: Heart rate target zones

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

The Precor SmartRate® technology is a precise,
easy-to-read heart rate monitor that helps users
achieve their best personalized workouts. SmartRate
displays actual heart rate information in relation to the
user’s target zone for weight loss and cardiovascular
training.

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.

The following diagram shows how the weight loss and
cardio heart rate zones vary depending on your age.

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

29

Precision Series / Energy Series Elliptical Fitness Crosstrainer Owner's Manual: EFX 425 / 423 / 225 / 222 / 221 30

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.

WARNING

Getting Accurate Heart Rate Readings

To work reliably, heart rate sensors need to be
securely in contact with your skin. Use the following
guidelines to make sure they are.

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.

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).

To attach a chest strap:

Measuring Your Heart Rate

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.

1. 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.

Figure 14: Moisten chest strap

31

Precision Series / Energy Series Elliptical Fitness Crosstrainer Owner's Manual: EFX 425 / 423 / 225 / 222 / 221 32

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.

Figure 16: Fasten chest strap

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

For touch-sensitive grips:

Readings

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.

No Heartbeat Icon or Heart Rate Display

The heart rate sensors may not be in secure contact
with your skin. Try the following solutions.

 Make sure that your hands grasp the

touch-sensitive 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.

Precision Series / Energy Series Elliptical Fitness Crosstrainer Owner's Manual: EFX 425 / 423 / 225 / 222 / 221 34

The Displayed Heart Rate Is Wrong Or
SmartRate Doesn’t Work

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.

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

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.

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).

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.

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
time-based 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.

Figure 19: Weight Loss

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.

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.

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.

Choosing and Completing a Workout

Figure 20: Basic HRC

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.

Precision Series / Energy Series Elliptical Fitness Crosstrainer Owner's Manual: EFX 425 / 423 / 225 / 222 / 221 40

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.

Note: If the equipment has a manually operated ramp,
we recommend adjusting it to the highest possible
setting before you begin.

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

Cross Country

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.

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.

Aerobic

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.

You can modify the CrossRamp setting for each
two-minute 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

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.

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
machine handles while maintaining an upright posture.

each segment of the profile reflects the last change
you made to the CrossRamp and resistance settings.
Challenge yourself by adjusting your training
parameters regularly for the best results.

Figure 23: Manual

Ending a Session

Cooling down is an important aspect of your workout
because it helps reduce muscle stiffness and soreness
by transporting excess lactic acid out of the working
muscles. In addition, a five-minute cooldown allows
your heart rate to return to its normal, resting state.

At the end of your workout, the Summary screen
displays the following information:

DANGER

Maintenance

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.

To reduce the risk of electrical shock,
always unplug the equipment from its
power source before cleaning it or
performing any maintenance tasks.

Inspection

Inspect the EFX before use.

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.

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

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.

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.

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.

Storing the Chest Strap

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).

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.

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.

WARNING

Getting Started

Thank you for choosing Precor. For proper installation, please read this guide
thoroughly and follow the assembly instructions. If you do not assemble the EFX
according to these guidelines, you can void the Precor Limited Warranty.

Obtaining Service

Do not service the EFX except for maintenance tasks as described in the owner’s
manual. For more information regarding customer support numbers or a list of
Precor authorized service dealers, visit the Precor web site at www.precor.com.

Installation Requirements

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.

Unpacking the Equipment

The EFX is carefully tested and inspected before shipment. The unit is shipped in
two boxes. Ask for help from one or more people to unpack and assemble the
treadmill. If any items are missing, contact your dealer.

Do not attempt to move the equipment by yourself. Have at
least one other person help you and use proper lifting
techniques.

To unpack the equipment:

1. Carefully cut and remove all plastic straps that secure the cover on the

cardboard box.

2. Lift the cover upward and set it aside.

3. Pull the cardboard or foam spacers away from the equipment and set them

aside.

4. Cut all plastic ties securing the equipment in place.

5. Remove and set aside the enclosed box and loose accessories.

6. Remove the base frame assembly from the container and set it on the floor

where you plan to assemble and use the 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.

 Adjustable wrench
 Wire cutter
 ⁹₁₆-inch socket wrench
 ¹₂-inch open-end wrench (for EFX 447 and 425 models only)

 Use your fingers or the appropriate tools to insert fasteners. Proper alignment

helps alleviate crossthreading. Do not fully wrench tighten fasteners until
instructed to do so.
