Calculating Training
Heart Rate
TARGET HEART RATE WORKSHEET
Name ___________________________
Class ____________________________
I. Calculate your maximal heart rate
(MHR). To do so, subtract your age in
years from 220. MHR is your heart rate at all-out
exertion.
220 - age = maximal heart rate (MHR) in beats
per minute:
220 - _______ = ____________ beats per minute
II. Calculate your resting heart rate
(RHR). Take your heart rate for 60
seconds, two mornings in a row. The average of
these two rates will be considered your current
resting heart rate. Be sure to take this heart
rate at a time when you are completely relaxed,
and that you have not consumed caffeine or any
other stimulant prior to taking your heart rate.
First morning heart rate + second resting
heart rate,
Divide total by 2 = average resting heart rate
(RHR) in beats per minute:
( ____________) + ____________ ) / 2 =
____________ beats per minute
III. Calculate your heart rate reserve
(HRR). If an individual calculates a
given percentage of his/her maximal heart rate
and uses this as a training heart rate, the
number obtained is actually an underestimation of
the actual workload. This is because the
percentage is taken from the range of zero beats
per minute to the maximal number of beats per
minute. Every living person, however, has a
minimal, resting heart rate (RHR) of greater than
zero beats per minute, whether that be 50 beats
per minute, 70 beats per minute, or any other
value. This resting heart rate must be accounted
for when calculating any training heart rate. To
do, so, subtract your RHR from your MHR before
calculating a training rate. The result is your
heart rate reserve (HRR).
Maximal heart rate - resting heart rate =
heart rate reserve:
____________ - ____________ = ____________
beats per minute (bpm)
IV. Calculate your minimal training
heart rate. This heart rate represents
your heart rate at minimal intensity during a
workout. The number is obtained by first
selecting a percentage of your maximal effort.
For this exercise, select 60% as your minimal
load. Use the decimal "0.60" to reflect
60%. Multiply this decimal by the HRR, then add
your RHR, which gives you your minimal training
heart rate.
.60 x heart rate reserve, then add your
resting heart rate = minimal training heart rate
in beats per minute:
( .60 x ____________ ) + ____________ =
____________ bpm
V. Calculate your maximal training heart
rate. 85% is the upper limit, and you
should not exceed this heart rate during
workouts, as your body will become quickly
fatigued and you may experience injury. Use the
decimal "0.85" to reflect 85%. After
multiplying the decimal by your HRR, add the RHR
to determine your maximal training heart rate.
0.85 x heart rate reserve, then add your
resting heart rate= maximal training heart rate
in beats per minute:
( 0.85 x ____________) + ____________ =
____________ bpm
