HEART RATE INFORMATION

CHOOsE A WORKOUT

• Determine your level of tness: beginner,

intermediate, or advanced.

• Determine your immediate goal: endurance

training, cardio-conditioning, or weight loss.

If you are a beginner, start with a cardio-conditioning

workout to gradually adjust your body to the demands of

exercise. Over a recommended eight-week period, you will

increase your endurance and strength.

For all tness levels, plan to exercise at an appropriately

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

strap to monitor your heart rate. Supplement your plans

with tness workouts from the Precor web site

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

expert advice to help you reach your tness goals.

MONITOR YOUR HEART RATE

The SmartRate and heart rate displays provide visual cues

that help you adjust your tness 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

2. Adjust the strap and fasten it around your chest.

The strap should feel snug, not restrictive

(Diagram B).

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 (Diagram C).

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) 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

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.

CAUTION: Your heart rate should never exceed

85% of your maximum aerobic heart rate or go

above your target zone (Diagram D).

COOl DOWN AFTER YOUR WORKOUT

Cooling down is an important aspect of your workout

because it helps reduce muscle stiness and

soreness by transporting excess lactic acid out of the

working muscles. Cooling down for at least three

minutes helps provide a smooth transition that allows

your heart rate to return to its normal, non-exercising state.

Diagram D: Heart Rate Target Zones

Diagram A Diagram B Diagram C

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.

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.

Figure 6: Motion controls

7. If you need to end your workout early, touch

Pause, then Finish, and finally Home.

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.

Getting Started

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.

Quadriceps (1–12, 19-20)

Gluteals (1-20)

Hamstrings (1–9, 19-20)

Calves (1–6, 16-20)

Figure 7: Muscle groups targeted by CrossRamp

Figure 8: Muscle groups targeted by CrossRamp
(200-series 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.

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) begins to flash.
 After a few seconds, the console displays your

current heart rate.

 If SmartRate is on, a second heartbeat icon

appears over your current heart rate zone (refer to
Using SmartRate).

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 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.

Figure 17: Heart rate target zones

On the Workout List, you can find several heart rate
workouts (refer to Available 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.

Precision Series / Energy Series Elliptical Fitness Crosstrainer Owner's Manual: EFX 447 / 245 28

Using SmartRate

You must be signed in under your user profile to use
this feature.

During your workout, SmartRate® maps your heart rate
on a scale of different target zones that show you what
kind of conditioning you’re getting. These zones are
defined as percentages of your maximum heart rate.
Your maximum heart rate is based on the following
formula:

Heart rate limit in beats per minute = 207 beats per
minute – (your age in years × 0.67)

At any time during your workout, your actual heart rate
is some percentage of this number. SmartRate uses
that percentage to find your current zone. For example,
if you were 35 years old and wanted to work out in the
suggested cardiovascular zone, your target heart rate
would be between 128 and 154 beats per minute.

(207-(35 × 0.67)) × 70% = 128 beats per minute

(207-(35 × 0.67)) × 84% = 154 beats per minute

The following table shows the percentage ranges for
each zone.

Table 2. SmartRate zone boundaries

Heart Rate Range SmartRate Zone

Less than 54% of
limit

Warm-up

55%–69% of limit Moderate (good for weight loss)

70%–84% of limit High (good for cardiovascular

conditioning)

Above 85% of limit Maximum

CAUTION: Your heart rate should never exceed 85% of
your maximum heart rate or go into the Maximum zone. If
it does, reduce the intensity of your workout
IMMEDIATELY.

Measuring Your Heart Rate

29

If SmartRate is on, you will see a heart rate indicator
(

) over the SmartRate zone bar during your workout.
This indicator shows where your current heart rate
falls within the active zone. You can then change the
intensity of the workout to stay within the zone you
want.

Figure 18: SmartRate zone bar

To make sure that SmartRate works correctly, you
need to make sure of the following things:

 Your age is properly set in your user profile.
 The equipment can read your heart rate properly. If

you are using a chest strap, you must moisten and
position it properly. If you are using the
touch-sensitive grips on the equipment, you must
maintain contact with both grips for five to ten
seconds.

Note: SmartRate is on by default, but it is not available
if the Guest account is selected.

To turn on SmartRate:

1. During your workout, touch Options.

2. At the Options screen, touch SmartRate On.

3. Touch Back to return to your workout.
Note: There is only one SmartRate button on the

Options screen. If SmartRate is currently on, the button
is named SmartRate Off. If SmartRate is currently off,
the button is named SmartRate On.

Precision Series / Energy Series Elliptical Fitness Crosstrainer Owner's Manual: EFX 447 / 245 30

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.

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.

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).

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 19: Moisten chest strap

Measuring Your Heart Rate

31

2. Adjust the strap and fasten it around your chest.
The strap should feel snug, not restrictive. Refer to
the following figure.

Figure 20: 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 21: 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.

Precision Series / Energy Series Elliptical Fitness Crosstrainer Owner's Manual: EFX 447 / 245 32

Setting Your Target Heart Rate

You must be signed in under your user profile to use
this feature.

Once you have set your target heart rate, some of the
built-in workouts can help you stay at that heart rate
for your entire exercise session.

Important: You cannot change your target heart rate
during a heart rate controlled workout. Also, your heart
rate setting is not saved along with your workout.

To set your target heart rate:

1. During your workout, touch Options.

2. At the Options screen, touch Change Target HR.

3. At the Set Target Heart Rate screen, use the up
and down arrow buttons to adjust your target
heart rate. As the rate changes, the corresponding
SmartRate zone for your age appears next to it.

Troubleshooting Heart Rate
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.

For touch-sensitive grips:

 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.

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.

Precision Series / Energy Series Elliptical Fitness Crosstrainer Owner's Manual: EFX 447 / 245 34

Choosing and
Completing a
Workout

The instructions shown earlier in this manual (refer to
Getting Started) provide the simplest possible steps for
getting started with your new fitness equipment. In
most cases, you’ll want to start with one of the
preprogrammed workouts available on the equipment.
This chapter explains how to select a workout and
describes the changes you can make as it progresses.

Note: If you’re signed in under your user profile, you
can save your completed workout as a personal
favorite and use it again later (refer to Finishing Your
Workout). If you’ve made any adjustments to the
intensity of the workout, your changes will be stored as
well.

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.

Choosing and Completing a Workout

35

The workouts on your Precor fitness equipment are
organized by goal. Under each goal there are workouts
of different types, which provide different benefits:

 Interval workouts help exercisers improve

strength, endurance, aerobic fitness, and anaerobic
fitness. They alternate between stages of higher
and lower intensity called work stages and rest
stages. During the rest stages, your metabolic and
heart rates slow down. Meanwhile, your body
takes in and distributes more oxygen for the next
work stage. Over time this pattern keeps your
calorie use up, promoting weight loss, improved
aerobic response, and increased overall stamina.
To improve your general fitness over time, start
with a 1-1 interval workout, then progress to the 2-1
workout, then the 4-1 workout. To enhance your
peak performance, choose a 1-2 or 1-4 workout and
set a challenging level for the work stages.

 Aerobic workouts are designed to keep your

oxygen consumption as high as possible, which
improves your fitness over time. Benefits of
aerobic conditioning include greater heart and lung
capacity, stress management, and an overall sense
of vitality.

 Weight loss workouts are designed to maintain a

steady-state, lower-intensity level of exercise,
keeping you in a workout zone that burns a higher
amount of fat calories.

 Toning and sculpting workouts focus on

improving the shape and definition of specific
groups of muscles.

 Terrain workouts simulate an outdoor run, walk,

or climb.

 Distance workouts simulate popular distance

runs.

 Heart rate controlled workouts hold you at an

optimal heart rate for your training goal by
adjusting intensity to keep you at a fixed exertion
level.

 The fitness test is a multi-stage test of increasing

intensity used to predict your maximum aerobic
capacity and estimate your current fitness level.

Tip: If you are signed in under your user profile, you
can adjust most workouts and save them as favorites.
The adjustments in your saved workout can be as
frequent as every 15 seconds. For example, to create a
high-intensity interval training (HIIT) workout, you can
make your work stages as short as 15 seconds.

Fitness Test

The Fitness Test consists of stages that last between
three and five minutes. The equipment prompts you to
choose the CrossRamp setting you want to use before
the test begins. Then, at each successive stage of the
test, the workout becomes more intense and the
equipment increases your target heart rate. After you
complete the test, the equipment displays your score.

The EFX ends the test prematurely if any of the
following things happen:

 The EFX cannot detect your heartbeat.
 Your heart rate exceeds 85% of your maximum

safe rate for 15 seconds or more.

 Your heart rate changes too quickly.
 You stop pedaling.

Important: For best results, sit and rest for at least five
minutes before you take the test. After the warm-up stage
of the test, you cannot adjust the CrossRamp or resistance
levels.

To see how your performance level increases with
exercise over time, try taking the fitness test as soon
as possible after you install the equipment. Then, as
you keep working out, take the fitness test from time
to time and watch your results improve.

outdoors—to help you stay focused on your fitness
goals. Through your iPhone device and Preva-equipped
Precor fitness equipment, Preva tracks all of your
workouts and lets you know whether you’re on track,
ahead, or behind your goals. It also helps you celebrate
major milestones in your progress (including some
with actual miles or kilometers) and keeps your
workout history.

To make sure Preva follows the progress you make
on your new fitness equipment:

1. If necessary, download the free Preva app from
iTunes

®

or the Apple App StoreSM.

2. Make sure that you are signed in to Preva.

Creating User
Profiles

When you first create your user profile, you start by
storing your personal information (age, weight, gender,
and workout focus). As you continue working out with
the equipment, it stores your progress and your
workout preferences. In other words, your user profile
allows the equipment to fine-tune itself to your needs.

Your user profile allows you to do the following things:

 Use SmartRate, or set your target heart rate, to

help ensure you get the cardiovascular workout
you want

 Receive workout suggestions based on your own

fitness focus

 Save favorite workouts and use them again later
 Set your own default workout duration and display

settings

 Automatically see accurate calorie use estimates

based on your age

 Track your progress throughout the week

Note: Some features of the equipment are available
only if you are signed in under your user profile. Those
features are identified with a user profile symbol (

The equipment can store profiles for up to four people.
Each profile has a unique color and a unique
name—you can enter your own name or leave the
"User number" name that the equipment first assigns
to your profile. When you select your profile later, the
equipment addresses you by name and all of the
screens are accented in your color.

Maintenance

71

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.

DANGER

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.

Precision Series / Energy Series Elliptical Fitness Crosstrainer Owner's Manual: EFX 447 / 245 72

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.

EFX 400 Series Assembly Guide 2

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

assembly process.

 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.

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.

Completing the Assembly

CAUTION: The location of the On/Off switch is beneath the cutout on the base frame.
Make sure the power switch is in the Off position. Make sure the power cord is
disconnected from its power source.

Connecting the Power Cord

CAUTION: Use the supplied power cord. Do not remove or otherwise bypass the
3-prong plug with an adapter in order to use a nongrounded outlet. Do not plug the EFX
into a power transformer in an attempt to adjust the voltage requirements. Failure to
follow these instructions might damage the unit and will void the Precor Limited
Warranty. If an appropriate cord for your location was not included with your EFX,
please contact your Precor dealer for the proper Precor power cord. For more
information on authorized Precor dealers in your area, please contact Customer
Support at www.Precor.com.

To connect the power cord:

1. Insert the power plug connector into its receptacle at the rear of the unit.

Figure 40: Plug location

2. Plug the other end into a grounded outlet so you can maintain a consistent

power source without overloading any other circuitry. Be sure to use the
appropriate voltage. Refer to Grounding Instructions in the Owner’s Manual.
