❤️ Heart Rate Zone Calculator
Estimated max heart rate and the 5 standard training zones as BPM ranges, from age — optionally refined with your resting heart rate (Karvonen method).
This is a general estimate based on standard published formulas, not medical advice. The "220 − age" max-heart-rate formula is a common simple approximation with well-known individual variation (±10-15 bpm is typical). Consult a healthcare provider before starting a new exercise program, especially with any heart condition.
