Tips and How HRC Works
CHAPTER TWO: HEART RATE CONTROL WORKOUTS
How the 
HRC System 
Controls 
your Heart 
Rate
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.
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. 
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.
