Pressing any key other than or will exit
HRC mode.
Adjust your target heart rate at any time during
your workout by pressing , using the
keys as needed, and pressing again. If you
are lowering your target, you are limited to a 5
bpm change.
The time and distance accumulated during
warmup are not counted against your selected
workout time or distance; those values start at
zero when the treadmill reaches heart rate control
mode. This time and distance are accumulated
into the workout summary data, as is your
cooldown exercise.
Interval HRC works just like constant heart rate
control up through the first work interval.
When your workout reaches your first rest
interval, your workload is reduced by half, and
kept at this rate throughout the rest interval.
The next work interval is initially set at an average
of the workloads in the previous work interval.
