Heart Rate Intensity Chart
We encourage you to use the Zone Finder (page 7) to determine your heart rate zones because it will provide you with
a very accurate correlation between your heart rates and actual effort. However, if you do not wish to use the Zone Finder,
you may also use the following chart to input your heart rate zones. Please note this chart will not be accurate for everyone.

Light Intensity
(60-70% of Max HR)
Exercise in this range at the
start of a workout or to recover
from a tough workout or race.
You should be able to easily
maintain a conversation while
exercising at this intensity.

Max Heart Rate
Moderate Intensity
(70-80% of Max HR)
Exercise in this range to develop
endurance and prepare your
muscles to make the transition
from aerobic to anaerobic.
You should be able to maintain
this for a while. You should not
be completely breathless and
this should not hurt.
Heavy Intensity
(80-90% of Max HR)
Exercise in this range
to increase muscle strength
and improve your anaerobic
threshold. This is uncomfortable.
You should be breathing very
heavily. You should only be able
to sustain this for a brief time.
Maximum Intensity
(90-100% of Max HR)
Exercise in this range to increase
mental toughness, Max V02 and
tolerance to lactic acid. This is
very uncomfortable. You can
barely sustain it. You should be
completely breathless. Do not
exercise at this intensity except
on the advice of a trained
medical professional.
