A normal resting heart rate for adults ranges from 60 to 100 beats a minute. Generally, a lower heart rate at rest implies more efficient heart function and better cardiovascular fitness.
For example, a 20-year-old person, the age-predicted maximal heart rate would be 194 beats per minute and for a 65-year-old person, the age-predicted maximal heart rate would be 163 beats per minute.
