Determining Your Target Zone
What is Target Zone Heart Rate Training? In order to benefit the most from your workout, you
need to become familiar with your heart rate training zone. By working within the correct range, you
will achieve your fitness goals and strengthen your cardiovascular system in less time. Here is basically
how it works.
Effective conditioning requires that you maintain your heart rate at the proper level for at least 20
minutes per workout (or per day). At too high of a heart rate your activity can become counter effective.
For most people, as your heart rate exceeds 85% (the upper limit), your body begins to become
anaerobic and produce acids. This also burns less fat which can begin to burn and strain muscles, and
even start storing fat. As for the Lower limit, this number tells you when you have reached a level of
intensity that is productive. A heart monitor will tune you into your body’s internal activity level and
helps prevent injury or worse.
To make this part easy for you, this monitor automatically sets the correct target zone for you, after
you enter in your age in the heart rate setup mode. The internal auto-setting is based on a generally
accepted standard range of 65 to 85% of your Max HR (where mHR = 220- Age).
There are many variations of formulas for calculating target zones. In most cases they will come up
with a range very close to or the same as the auto-setting of this watch. If you prefer to fine-tune or
program your own limits, this can also be done in the HR Setting Mode (see page 7). The internal
automatic TZ calculation is based on the following example:

220 - Your Age = Max HR
(For a 30 year old, your calculations would be as follows.)
220 - 30 = 190 Maximum heart rate (mHR)
65% of this number = 123.5
85% of this number = 161.5
