DETERMINING YOUR TARGET HEART RATE
One of the first steps to using a Heart Rate Monitor is to
determine your Target heart rate Zone (TZ). It is always best
to consult with your physician first, and it is especially
important if you have a history of heart disease. Never use
a Heart Rate Monitor if you have a pacemaker without first
consulting your physician. Below are some general
guidelines for your reference.
TARGET HEART RATE ZONE
The American Heart Association recommends the following
formula for calculating your Target heart rate. First find your
maximum heart rate:
220 minus Your Age = Maximum Heart Rate
Your Target heart rate Zone is a percentage of your
maximum heart rate (see chart on opposite page). The
American Heart Association recommends working out at a
Target Zone of between 60% and 75% of your maximum
heart rate. If you are just beginning an exercise program,
exercise between 50% and 60% of your maximum heart
rate. If you have already been exercising regularly and are
looking to improve your performance, you can consider
exercising in the athletic training Target Zone of 75% to
90% of your maximum heart rate.
