Overview

Endurance athletes often have a lower resting heart rate than others. Heart rate is measured in beats per minute (bpm). Your resting heart rate is best measured when you’re sitting or lying down, and you’re in a calm state.

The average resting heart rate is usually between 60 and 80 bpm. But some athletes have resting heart rates as low as 30 to 40 bpm.

If you’re an athlete or someone who exercises often, a lower resting heart rate isn’t usually anything to be worried about, unless you’re dizzy, tired, or ill. In fact, it typically means you’re in good shape.

Athlete resting heart rate

An athlete’s resting heart rate may be considered low when compared to the general population. A young, healthy athlete may have a heart rate of 30 to 40 bpm.

That’s likely because exercise strengthens the heart muscle. It allows it to pump a greater amount of blood with each heartbeat. More oxygen is also going to the muscles.

This means the heart beats fewer times per minute than it would in a nonathlete. However, an athlete’s heart rate may go up to 180 bpm to 200 bpm during exercise.
