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.
What should your heart rate be? It used to be thought that a normal resting heart rate is somewhere between 60-100 beats per minute (bpm). Many experts now believe that 60-80bpm is a more healthy level. However some people naturally have a lower or more rapid pulse. Your heart rate can alter as you get older as well and it can also indicate a change to your health. If your resting rate is consistently below 40bpm or above 120bmp, you should see your GP to check if thatâs normal for you.
