T=0.70 (M)
T = Target heart rate
M = Maximum heart rate = 220 - age
For example, Geoff is 21 years old; therefore, Geoff's target heart rate would be figured as follows:
Maximum Heart Rate:
M = 220-age
M = 220 - 21 = 199
Target Heart Rate:
T = 0.70 (M)
T=0.70 (199)
T=139.3 (round down)
T = 139
Figure Your Target Heart Rate:
Step 1: Determine your maximum heart rate.
M = 220 - [your age]
M = 220 -
Step 2: Plug your answer for M into target heart rate formula. Calculate your target heart rate.
T = 0.70 (M)
T = 0.70
