Owner’s Manual: Heart Rate Features 9
Exercise to Your Target Heart Rate
The 9.21 treadmill includes a program that lets you
exercise based on a specified heart rate. You set your
target heart rate (THR) and the speed of the running belt
after selecting the program. As you exercise, the Heart
Rate Control Program monitors your heart rate and
automatically maintains it within a few beats per minute
(bpm) of your selected target. Your actual heart rate
appears in the HEART RATE display.
To use the Heart Rate Control Program, select HRC. You
must also wear the chest strap so the program can monitor
your heart rate throughout the workout. For more
information, refer to Heart Rate Control (HRC) Program.
