KNOW YOUR DATA
To help achieve the maximum health benefits from your
workout program, it is important to know your:
• Maximum heart rate (MHR) training zone
• Upper heart rate limit
• Lower heart rate limit
MHR is expressed in beats per minute. You can get your
MHR from a MHR test, or you can estimate it using the
following formula:
220 - age = MHR
There are several training zones that are relevant to a
fitness program. The most popular zone range is from
50% to 80% of your maximum heart rate. This is where
you achieve cardiovascular benefits, burn fat, and become
fitter. When programming your watch, the lower % of the
zone you choose becomes your lower heart rate limit and
the higher % becomes the upper heart rate limit.

The upper and lower heart rate limits are calculated by
multiplying your MHR by the percentages of the selected
training zone.
For example:
A 40-year-old user training for basic health maintenance:
• His Upper Heart Rate Limit [220 - 40(age)] x 78%
• His Lower Heart Rate Limit [220 - 40(age)] x 65%
TRAINING ZONES
Always warm up before exercising and select the training
zone that best suits your physique. Exercise regularly, 20
to 30 minutes per session, three to four times a week for a
healthier cardiovascular system.
