HR Control Interval Program

In the HR Control Interval workout, the user can define an exercise Target HR, time at exercise Target HR, a recovery Target HR, time at recovery Target HR, and total # of HR intervals (1 HR interval = 1 exercise Target HR interval + 1 recovery Target HR interval).

To use the HR Control Interval program:

1.Press [ADVANCED PROGRAMS] workout key, followed by the Speed UP key until the controller displays “HR CONTROL INTERVALS” (2100 LC) or “HR INTERVALS” (2100 LE). Press ENTER to accept.

2.The controller will display “ENTER WEIGHT - LBS” (or “ENTER WEIGHT - KG” if in Metric mode). Enter your weight using the numeric keypad and press [ENTER]. Or, press [ENTER] to accept the default value.

•Your weight is used to calculate the number of calories burned for each minute of exercise and the total number of calories burned for the exercise session.

3.The controller will display “ENTER AGE 10 -99.” Enter your age using the numeric keypad and press [ENTER]. Or, press [ENTER] to accept the default value of 40 years old.

4.The controller will display “REST TARGET HR.” A suggested rest target heart rate will be displayed, based on your age and represents 65% of your age-predicted maximum heart rate. Press [ENTER] to accept the calculated target heart rate, or enter a different target heart rate using the numeric keypad and then press [ENTER]. Or, press [ENTER] to accept the default value.

•The target heart rate selected by the controller is based on age, and is equal to

65% of your maximum heart rate which is calculated by the following equation: (215 – (Age*.75)) x .65 (where Max HR = 215 – (Age*.75)). If desired, change the target heart rate at this point by using the numeric keypad to enter the new target heart rate, and then press [ENTER].

•Change to a new target heart rate that is between 80 and 180 beats per minute at any time during a workout by using the numeric keypad to enter the new target heart rate, and then pressing [ENTER]. A change in target heart rate does not reset any speed or incline overrides made prior to the target change.

5.Next, the controller will display “ENTER REST TIME”. Enter the desired interval time for the rest stage using the numeric keypad and press [ENTER] to accept. Or, press [ENTER] to accept the default value of 2 minutes.

∙ NOTE: The Rest Time does not start until your heart rate is within 5 beats/minute of the Target Rest Heart Rate.

∙ Valid Rest Times are between 30 seconds and 49 minutes.
