The normal range for resting heart rate in adults, male or female, is between 60 to 100 beats per minutes, says Mayo Clinic. Many factors affect the pulse, but lower resting heart rates indicate good heart health.
Endurance athletes frequently have a lower-than-normal resting heart rate, often as low as 40 beats per minute, due to their activity level and cardiovascular fitness. Body position, temperature, activity level and many other situational factors also influence heart rate. However, when checking resting heart rate, it is advisable to follow up with a medical professional if it measures outside the range of 60 to 100 beats per minute.
