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 well-trained athlete might have a normal resting heart rate closer to 40 beats a minute.To measure your heart rate, simply check your pulse. Place your index and third fingers on your neck to the side of your windpipe.or example, a well-trained athlete might have a normal resting heart rate closer to 40 beats a minute.

A normal resting heart rate -- your heart rate when you're completely at rest -- for the average adult is 60 to 80 beats per minute. People who are very physically fit often have slightly lower resting heart rates. Also, heart rate, much like weight, tends to increase with age.or adults, a normal resting rate is 60 to 100 beats per minute. Athletes may have a rate as low as 40 bpm because their hearts are trained to efficiently pump blood.
