Owner’s Manual: Programs 23
Walk (WALK) Program
The Walk Program is a great
cardio-conditioning program for
both beginners and serious
walkers. The incline is
preprogrammed. The
percentage of incline and the
frequency with which the
columns change determine the
level of difficulty. You can change the speed and override
the preprogrammed incline using the arrow keys. As you
move through the program, the columns are repeated until
the time limit is reached.
Heart Rate Control (HRC) Program
The Heart Rate Control (HRC)
Program lets you set a target for
your heart rate. The program
adjusts the incline to maintain
your heart rate within two beats
per minute of the target heart
rate (THR) while you exercise.
The initial THR is determined
using a simple calculation:
(220 minus your age) multiplied by 70%
During your workout, the number that represents your
heart rate appears in the HEART RATE display.
For information about understanding your target heart rate,
refer to Heart Rate Features.
Important: Consult your physician to determine the
appropriate target heart rate for your age and fitness level.
If your physician recommends a different target heart rate
than the one that appears on the display, use the
INCLINE arrow keys to change the target heart rate once
you finish the warm-up period. Do not work out over the
recommended range.
