What This Means
Elite-level cardiac efficiency
You are in the top tier for resting heart rate in your age group, comparable to trained endurance athletes. Your heart is exceptionally efficient, delivering maximum output with minimal effort at rest. This level of cardiovascular fitness is associated with excellent longevity outcomes. Focus on maintaining balanced training, quality recovery, and avoiding chronic overtraining.
How to Improve
Maintaining elite cardiac efficiency
- Monitor resting heart rate trends to detect overtraining or illness early
- Periodize training with planned recovery weeks every 3-4 weeks
- Fine-tune nutrition and hydration timing around training sessions
- Balance high-intensity work with adequate parasympathetic recovery activities
Measuring with Apple Watch
Apple Watch measures resting heart rate throughout the day during periods of inactivity, providing a daily average. Garmin, Fitbit, COROS, Polar, and Whoop also track resting heart rate using optical heart rate sensors. The classification tables on this page apply regardless of which device you use. Resting heart rate is best measured first thing in the morning before getting out of bed, though wearable averages across the day are also reliable for tracking trends.
