Precor 5.17i, 5.19, 5.21i Warm-up Period, Using the HRC Program

Owner’s Manual: Programs 29
Important: Consult your physician to determine the
appropriate target heart rate for your age and fitness level. If
your physician recommends a different target heart rate than
the one that appears on the display, use the appropriate
RESISTANCE arrow keys to change the target heart rate
once you finish the warm-up period. Do not exercise over
the recommended range.
Warm-up Period
The EFX provides a 3-minute warm-up period. During this
time, you may change the resistance or ramp incline.
Note: If your heart rate moves into the target heart rate zone
during the 3-minute warm-up period, the warm-up period
ends and the Heart Rate Control program begins.
Using the HRC Program
When the warm-up period concludes,
• The EFX automatically adjusts the resistance to keep
your heart rate at the selected target. Pressing the
RESISTANCE arrow keys no longer affects the resistance
applied to your stride, but does change the target heart
rate. Check the SmartRate display to see if you are
maintaining your preferred zone (weight loss or
cardiovascular). Your actual heart rate appears in the
display when the HEART RATE LED is lit.
Important: Maintain a constant stride rate between 100
and 150 strides per minute. Automatic adjustments to the
resistance cannot take place if you drop below 20 strides
per minute.
• You can change the target heart rate, strides per minute,
or ramp incline, but doing so 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.
Note: If you are having difficulty with the heart rate
features, refer to Troubleshooting Heart Rate.
