Workout Pulse Rate Calculator
This calculator helps you estimate your target heart rate zones for exercise, which is crucial for effective and safe training. Your heart rate is a key indicator of your body's response to physical activity.
Understanding Target Heart Rate Zones
Your maximum heart rate (MHR) is approximately 220 minus your age. Exercising within specific heart rate zones allows you to achieve different fitness goals:
- Moderate Intensity (50-60% of MHR): Good for improving general fitness and recovery.
- Vigorous Intensity (70-85% of MHR): Excellent for improving cardiovascular endurance and burning calories.
- High Intensity (85%+ of MHR): Typically used by athletes for peak performance training.
It's always recommended to consult with a healthcare professional before starting any new exercise program, especially if you have pre-existing health conditions.
