Using SmartRate

You must be signed in under your user profile to use
this feature.
During your workout, SmartRate
on a scale of different target zones that show you what
kind of conditioning you're getting. These zones are
defined as percentages of your maximum heart rate.
Your maximum heart rate is based on the following
formula:
Heart rate limit in beats per minute = 207 beats per
minute – (your age in years × 0.67)
At any time during your workout, your actual heart rate
is some percentage of this number. SmartRate uses
that percentage to find your current zone. For example,
if you were 35 years old and wanted to work out in the
suggested cardiovascular zone, your target heart rate
would be between 128 and 154 beats per minute.
(207-(35 × 0.67)) × 70% = 128 beats per minute
(207-(35 × 0.67)) × 84% = 154 beats per minute
