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.
