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.
