What Is a Normal Heart Rate? Whatâs normal depends on your age and activity level, but generally a resting heart rate of 60-80 beats per minute (BPM) is considered to be in the normal range. If you are an athlete, a normal resting heart rate can be as low as 40 BPM.
While the normal resting heart rate for adults ranges from 60-100 beats per minute, conditioned. athletes and other highly fit individuals might have normal resting heart rates of 40-60 beats per minute. For healthy adults, a lower heart rate at rest generally implies more efficient heart function and better. cardiovascular fitness. Gender is another factor in resting heart rate norms because women at various fitness levels tend to. have higher pulse rates on average than men of comparable fitness levels. For example, the average. resting heart rate of an elite 30-year-old female athlete ranges from 54-59 beats per minute, while the.
