This maximum rate is based on the person's age. An estimate of a person's maximum age-related heart rate can be obtained by subtracting the person's 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).
It is typically considered to be 60% of your maximum heart rate, which again depends on your age, gender, and weight. For a 30 year-old male (if I remember the chart on the treadmill correctly), a max heart rate is about 190bpm. High intensity (aerobic) exercise should be at 80% (up to 85%) of your max heart rate.
