HEART RATE CONTROL PROGRAM
How the Heart Rate Control Programs Work：
Heart Rate Control (HRC) uses your treadmill's incline system to control your heart rate.
Increases and decreases in elevation affect heart rate much more efficiently than changes in
speed alone. The HRC program automatically changes elevation gradually to achieve the
programmed target heart rate.
Selecting a Heart Rate Control Program:
You have the option, during the setup mode, to choose either the HR program. The Weight
Control program will attempt to maintain your heart rate at 65% of your Maximum Heart Rate.
Your Maximum Heart Rate is based upon a formula that subtracts your age from a constant of
220. Your HR setting is automatically calculated during the setup mode when you enter your
age.
