Resting heart rate as a fitness indicator
A lower number at rest isn't automatically better in isolation, but the trend over time tells a real story.
Resting heart rate reflects how many times the heart needs to beat per minute to maintain adequate circulation at rest — a well-conditioned cardiovascular system typically achieves this with fewer, more forceful beats, which is why endurance athletes often show resting rates well below the general population average.
Normal resting heart rate spans a fairly wide range — roughly 60 to 100 beats per minute for most adults — which means a single reading in isolation is less useful than tracking your own trend over weeks and months.
A rate that's unusually low for you but accompanied by dizziness or fatigue, or one that's persistently elevated at rest without an obvious cause like illness or stress, are both worth flagging to a physician rather than assuming lower is always better.
Aerobic training is the most consistent lever for lowering resting heart rate over time, typically showing measurable change over 8-12 weeks of consistent cardiovascular exercise.
