Controls
your Heart
Rate
The treadmill operates in a manual control mode during the
warm-up stage. You control both speed and incline. You may
only increase speed and incline to the preset maximum values
entered.
Increase speed and incline gradually to slowly increase your
heart rate to within 10 bpm of your target. For best results, you
should take about five minutes to get to that point.
It is important that you start at a low level of effort and gradually
increase your work load over several minutes until you approach
your target heart rate. This allows your body to adapt to your
workout. Increasing work load gradually will allow you to enter
the heart rate control stage without overshooting your target.
Warming up too fast may cause you to overshoot your target.
If this occurs, it may take several minutes before the computer
software can control your heart rate. You may overshoot and
undershoot your target for several minutes until stable control is
achieved.
To raise your heart rate in HRC mode, speed will always increase
until maximum speed is attained, followed by incline (if incline is
used in the workout).
To lower your heart rate in the HRC mode, incline will always
decrease until zero incline is reached, followed by speed (if
incline is used in the workout).
Speed changes are in 0.1 mph increments. Incline changes are in
0.5% incline increments. This is equal to between 0.10 and 0.15
METs.
