The ideal range for resting heart rate in a healthy adult is typically between 60 and 100 beats per minute. A resting heart rate at the lower end of this range generally indicates better cardiovascular fitness, as it often reflects a more efficient heart function. Athletes, for instance, may have resting heart rates below 60 bpm due to their training. Monitoring resting heart rate can provide insights into overall health, fitness levels, and potential abnormalities, serving as an important indicator of heart health and readiness for physical activity.
