Diagram 6: Heart rate target zones
•The target heart rate is determined using a simple calculation:
(220 minus age) multiplied by 70%
Owner’s Manual: Heart Rate Features |
10 |
•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.
•Always face forward on the EFX and use the stationary handrail for balance.
•If three dashes (— — —) appear on the display, the EFX cannot detect a heart rate. Make sure the chest strap is positioned properly around your chest and against your skin.
•Maintain a constant stride rate while exercising. Find a comfortable stride rate between 100 and 150 strides per minute.
Using SmartRate
The SmartRate feature helps you monitor and maintain your heart rate in the target zone best suited to your specific needs. All 15 LEDs light during a workout. When you wear the chest strap, a single LED blinks and indicates the zone that your heart rate is in, either weight loss or cardiovascular.
The 15 LEDs in the SmartRate display are color-coded. A pulsating red LED indicates you are outside the
recommended heart rate target zone. Yellow LEDs indicate when you are exercising within the weight loss zone. Green LEDs indicate when you are exercising within the cardiovascular zone.
Refer to Table 1 to see the relationship between the pulsating LED and your target heart rate.
The SmartRate indicator lights do not appear when:
•You press QUICKSTART at the banner.
•You bypass the AGE prompt.
•You do not wear or improperly position the chest strap.
Note: Review the information on the QUICKSTART card that accompanies your literature packet. It explains how to adjust the chest strap.
CAUTION: Your heart rate should never exceed 85% of your maximum aerobic heart rate. If it does, immediately reduce your strides per minute or, if possible, adjust the ramp incline to return your heart rate to your physicianrecommended target zone.

Exercise to Your Target Heart Rate
The EFX includes a program that lets you exercise based on a specified heart rate. You set your target heart rate at the beginning. As you exercise, the Heart Rate Program monitors your heart rate and automatically maintains it within a few beats per minutes (bpm) of your selected target. Your actual heart rate (pulse) appears in the Heart Rate display.
To use this program, select HRC. You must also wear the chest strap so the program can monitor your heart rate throughout the workout. For more information, refer to Heart Rate Control (HRC) Program.

The following information describes the information that appears in the center display. The information is shown in alphabetic order.
CALORIES—displays the estimated cumulative number of calories burned. The calorie calculation is derived from the pedaling speed, resistance level, and your weight. An accurate weight entry results in a more accurate calorie count. When using QUICKSTART and a weight has not been specified, the default weight is 150 pounds (68 kilograms).
CALORIES/MINUTE—displays the approximate number of calories burned per minute.
DISTANCE—shows a linear distance in either miles or kilometers. The distance is calculated based on the amount of energy you expend during your workout, and is equal to a distance that you might run or walk using the same amount of energy.
PROFILE—appears on the display and corresponds to the program you selected. As you continue your workout, a blinking column indicates your position in the program.
•On the EFX5.23, the height of the column indicates the level of incline.
•On the EFX5.33, the height of the column indicates the level of resistance.
If the profile is only one cell high, then markers (
) appear occasionally and provide a sense of movement through the program.
STRIDES—shows the total number of strides completed, which is always an even number since two strides create one complete revolution of the flywheel. A stride is an exaggerated walking movement. On the EFX, if you start in a position with one foot pedal forward, a stride is completed when you move the rear foot pedal all the way forward while the other foot pedal moves to the rear.
Owner’s Manual: Display Console |
14 |
STRIDES/MINUTE—displays your current pedaling speed (strides per minute) up to a maximum value of 510 strides per minute. When the strides per minute drops below 20, the EFX reverts to pause mode.
Important: The display may not change as quickly as your stride. For example, when you stop suddenly from a high stride rate, the display does not immediately change to zero. Instead, it gradually decreases until it reaches zero.
TIME—displays workout time in minutes and seconds; however, when you exceed 60 minutes during a single workout, the TIME display converts to hours and minutes. For programs with a workout time limit, the TIME display shows the amount of time remaining. For programs without a workout time limit, the TIME display indicates the amount of time you have been exercising.
USER 1 and USER 2—shows the current user selection after a user key has been pressed at the banner. For more information, refer to Selecting a User ID.
WATTS—displays the current mechanical energy generated by the unit.
