The formula used for each zone above is:
(MHR - RHR) * % + RHR
The maximum heart rate (MHR) is calculated using the age input. Every year 30 and below is expected to decrease maximum heart rate by one from a starting value of 220. Every year above age 30 each year counts only half a beat in that difference.
The percentages used are as follows:
UT2 = 59%-67%
UT1 = 67%-75%
AT = 75%-85%
TR = 85%-100%
