For moderate-intensity physical activity, your target heart rate should be between 64% and 76%1,2 of your maximum heart rate. You can estimate your maximum heart rate based on your age. To estimate your maximum age-related heart rate, subtract your age from 220. For example, for a 50-year-old person, the estimated maximum age-related heart rate would be calculated as 220 – 50 years = 170 beats per minute (bpm). The 64% and 76% levels would be:
64% level: 170 x 0.64 = 109 bpm, and
76% level: 170 x 0.76 = 129 bpm
