CAUTION: Keep in mind that the “Heart Rate” or “Training” zones are approximations. Always check with your physician to learn what the appropriate heart rate is for your level of fitness.
Utilizing the Heart Rate Interactive Capabilities
You can make each program on the EFX a heart rate interactive course by monitoring and maintaining your heart rate in the Smart Rate zone best suited for your specific needs. You can access Smart Rate only if the optional heart rate receiver is installed in your unit and you wear the Precor chest strap. The Smart Rate indicator lights do not appear when you use Quick Start.
Before using the Heart Rate capabilities on the EFX, take time to read the following guidelines.
•Consult with your physician before engaging in any vigorous exercise. Do not use the Heart Rate Control Course until authorized by your physician.
•Slow down and stop immediately if you experience any pain or abnormal symptoms.
•Gently stretch you lower body and back before and after working out to help prevent stiffness or soreness.
•Know your heart rate (pulse) and your
•You should not use the Heart Rate capabilities if you are taking any medications that either speed up or slow down your heart rate.
•Always face forward on your EFX and use the handrails for balance. Try not to use the handrails to support your weight.
•Keep in mind that you are working with very sensitive equipment and upper body movement should be kept to a minimum.

CAUTION: Always check with your physician to learn what the appropriate heart rate is for your level of fitness. Do not push yourself beyond the recommended range.
Using the EFX Heart Rate Control Course
The EFX Heart Rate Control Course has been designed from research conducted at the world- renowned Cooper Institute for Aerobics Research. The HRC program must be used in conjunction with the Precor Heart Rate Option. You can use the HRC program to maximize your aerobic workout. Once you start the program, select a ramp position that gives you the elliptical movement and workout that you want. The EFX software automatically adjusts the resistance (or prompts you to increase the strides per minute, if necessary) to keep your heart rate within the cardiovascular heart rate zone.
Important: During your workout, you should strive to maintain a comfortable and constant stride rate above 100 spm. Otherwise the system will continually overcompensate and the resistance levels will be moving up or down more often.
To use the course follow the steps in Working Out on the EFX and choose “HRC” at the course prompt. The following occurs:
