What is Target Heart Rate Zone?
Target Heart Rate Zone tells you 
the number of times per minute 
your heart needs to beat to 
achieve a desired workout effect. 
It is represented as a percentage 
of the maximum number of times 
your heart can beat per minute. 
Target Zone 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. A beginner will want to 
workout in the 60% range while 
a more experienced exerciser will 
want to workout in the 70-75% 
range. See chart for 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 maximum 
Heart Rate = 135 Beat Per Minute.
ALWAYS CONSULT YOUR PHYSICIAN BEFORE BEGINNING AN ExERCISE PROGRAM.
