HEART RATE CONTROL WORKOUTS
550ZTX Treadmill Owner’s Guide

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.
