1 Your heart rate reserve (HRR) is your max heart rate minus your resting heart rate. 2  Know your zones. 3  To find out which numbers to target on which runs, multiply your heart rate reserve by the zone youâre running in, then add back your resting heart rate. Letâs say you have a max heart rate of 190 and a resting heart rate of 60. 2  Your heart rate reserve would be 190 â 60 = 130. 3  To find out which number you should target for your warmup, when you want to be working at 65%, youâd use this formula: 4  Heart Rate Reserve x 65% + Resting heart rate.
