Understanding Heart Rate Zones
Heart rate zones represent different exercise intensity levels:
- Moderate Intensity (50%–70% of maximum heart rate): Suitable for improving general fitness and supporting weight management.
- Vigorous Intensity (70%–85% of maximum heart rate): Ideal for improving cardiovascular endurance and athletic performance.
- Heart Rate Reserve (HRR): The difference between your maximum heart rate and resting heart rate, often used in personalized training programs.
These values are estimates and may vary depending on your overall health, medications, fitness level, and individual physiology.
