How to Use the Heart Rate Zone Calculator
Enter your age and any optional resting-heart-rate input, then review the estimated zones for easy, moderate, tempo and high-intensity training.
Practical Example
If estimated maximum heart rate is 190 bpm, a 70% training zone is about 133 bpm and an 80% zone is about 152 bpm.
Factors That Affect the Result
Maximum-heart-rate formulas are approximations. Fitness, medications, fatigue, heat, altitude, hydration and individual physiology can shift your real training zones.
Frequently Asked Questions
How many heart rate zones are commonly used?
Many training systems use five zones, though exact boundaries differ.
Are higher zones always better?
No. Different zones serve different training goals and recovery needs.
Can a wearable measure zones perfectly?
Wearables are useful but can still have measurement error.
