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.
The normal resting heart rate for an adult is between 60 and 100. The typical healthy resting heart rate in adults is 60-80 bpm, with rates below 60 bpm referred to as bradycardia, and rates above 100 bpm referred to as tachycardia. Note howâ¦ever that conditioned athletes often have resting heart rates below 60 bpm. 70-75 beats a minute.
