TARGET HEART RATE ZONE
Your ‘Target Heart Rate Zone’ is a percentage of your maximum heart rate. Target Zones will vary for
each individual, depending on age, current level of conditioning, and personal fitness goals. The
American Heart Association recommends working-out at a ‘Target Heart Rate Zone’ of between 60%
and 75% of your maximum heart rate. See the chart below for convenient reference. Example for a
42-year old user: find AGE along the bottom of the chart (round to 40), follow AGE column up to the
TARGET ZONE BAR. RESULTS: 60% of maximum Hear Rate = 108 Beats Per Minute, 75% of maxi-
mum Heart Rate = 135 Beat Per Minute.
