Precor efx 5.25, EFX 5.23 manual

•The program sets the default target heart rate as 70% of 220 minus your age. Changing your stride rate or CrossRamp affects the unit’s ability to maintain your target heart rate in the preferred zone. It takes time for the EFX to readjust the resistance so that your heart rate remains on target. Check the SmartRate and the HEART RATE displays to see if you are maintaining your preferred zone and to determine your actual heart rate. For information about understanding your target heart rate, refer to Heart Rate Features.

•Changes to the CrossRamp are reflected in the program’s profile. Automatic resistance changes appear in the RESISTANCE display.

•A cool-down period is incorporated into the program.
