Basic Heart Rate Control
This workout monitors your heart rate to guide you
through a moderate intensity program that is optimal
for aerobic conditioning.
During the workout, your target heart rate is based on
the following calculation:
Target heart rate = 70% × (207 – (0.67 × your age))
The equipment adjusts resistance, CrossRamp level, or
both to maintain your target heart rate while you work
out.
When a heart rate signal is not received, a heart shape
with a question mark appears in the upper text display.
Recheck your hand grip on the handheld sensors or the
placement of your chest strap.
Training tip: This program offers a coaching benefit for
new and returning users who are learning how to
maintain a moderate, steady exertion level throughout
their workouts.

Note: For the unit to detect your heart rate, you must
grip the handheld heart rate sensors or wear a chest
strap while exercising. In the presence of both
handheld and wireless data, the handheld data takes
precedence and is displayed.
