The Heart Rate Zone Calculator is a precision engine designed to optimize athletic performance through physiological accuracy. By utilizing the Karvonen method, it calculates heart rate ranges based on your Heart Rate Reserve (HRR), ensuring that training intensity is personalized to your specific cardiovascular fitness level. The tool supports multiple disciplines including running, cycling, and swimming, applying necessary sport-specific modifiers to intensity boundaries. Use get_max_heart_rate to establish your physiological ceiling, calculate_training_zones to define your metabolic targets, and get_workout_distribution to plan session durations aligned with goals like Endurance, Threshold, or VO2 Max development.

What is my max heart rate if I am 30 years old and recently recorded 185 bpm in a test?

Your maximum heart rate is 185 bpm, based on your recent field test result.

Calculate my training zones for cycling with a max HR of 190 and resting HR of 60.

For cycling, your zones are: Zone 1: 123-135 bpm, Zone 2: 135-147 bpm, Zone 3: 147-159 bpm, Zone 4: 159-171 bpm, and Zone 5: 171-190 bpm.

How should I distribute a 60 minute workout for a VO2 Max focus?

For a Power/VO2 Max Focus, your 60-minute session should be distributed as: Zone 1: 5 mins, Zone 2: 5 mins, Zone 3: 10 mins, Zone 4: 25 mins, and Zone 5: 15 mins.

The `get_max_heart_rate` tool uses either a field test result if provided, or calculates an estimate by subtracting your age from 220.
