📐 How heart rate zones work

Heart rate zones help you train at the right intensity. Here are the formulas:

Heart rate formulas:

Max HR = 220 - Age
Karvonen = ((Max HR - Resting HR) × %Intensity) + Resting HR
Tanaka = 208 - (0.7 × Age)
  • Zone 1 = 50-60% (Warm-up / Recovery)
  • Zone 2 = 60-70% (Fat Burning)
  • Zone 3 = 70-80% (Cardio / Endurance)
  • Zone 4 = 80-90% (Performance / Speed)
  • Zone 5 = 90-100% (Maximum Effort)
Example: 30 years old, resting HR 70
Max HR = 220 - 30 = 190 bpm
Zone 2 (60-70%) = 114-133 bpm

Key insight: Training in different zones targets different fitness goals - fat loss, endurance, or performance.

Formula Used

Result = the equation or estimation model selected in this calculator, applied to the entered measurements. A numerical check does not establish clinical validity; review the method and limitations.

How the formula is applied

The calculation links Age, Resting heart rate and Gender to maximum heart rate. A zone boundary expresses a percentage or reserve-based share of an estimated maximum. It does not prove that the intensity is appropriate for an individual.

Calculator Description

Enter Age, Resting heart rate and Gender and the remaining scenario settings to review maximum heart rate with this tool. A zone boundary expresses a percentage or reserve-based share of an estimated maximum.

Explore the relationship between entered age, resting pulse and the heart-rate estimates offered by the tool. Keep an estimated maximum separate from a measured exercise pulse.

A zone boundary expresses a percentage or reserve-based share of an estimated maximum. It does not prove that the intensity is appropriate for an individual.

Frequently Asked Questions

What information do I need for the Heart Rate Calculator?

Prepare Age, Resting heart rate, Gender, Fitness level and Calculation method. Check which zone method is selected and use a measured resting pulse only in a field that requests it.

How do maximum heart rate and a training zone differ?

A zone boundary expresses a percentage or reserve-based share of an estimated maximum. It does not prove that the intensity is appropriate for an individual. Medications, fitness, health conditions and prediction error affect heart-rate interpretation. The tool does not assess symptoms or establish exercise clearance.

How can I check the heart rate calculator with an example?

Use the full settings in the worked-example table. They produce Maximum Heart Rate: 190. Compare the method and units as well as the displayed number.

Which assumptions apply to this heart rate calculator?

The displayed relationship is Result = the equation or estimation model selected in this calculator, applied to the entered measurements. A numerical check does not establish clinical validity; review the method and limitations. Check which zone method is selected and use a measured resting pulse only in a field that requests it.

When should I verify the heart rate calculator result elsewhere?

Medications, fitness, health conditions and prediction error affect heart-rate interpretation. The tool does not assess symptoms or establish exercise clearance. For personal care, discuss the measurements and method with a qualified clinician.

How to Use This Calculator

  1. Check which zone method is selected and use a measured resting pulse only in a field that requests it.
  2. Fill in Age, Resting heart rate, Gender and Fitness level; then complete the other fields shown for your selected mode. Use the field units rather than copying an unlabeled value.
  3. For a result check, reproduce the example beginning with Age = 30 and Resting heart rate = 70; copy the remaining settings from the detailed guide.
  4. Use the page's Calculate or Convert control, or read the updated result where the tool recalculates automatically. Locate Maximum Heart Rate and any supporting breakdown.
  5. Interpret the result with this distinction in mind: A zone boundary expresses a percentage or reserve-based share of an estimated maximum. Keep the selected inputs alongside the output when comparing scenarios.

Practical example and result check

Worked heart rate calculator example. Set Age = 30; Resting heart rate = 70; Gender = Male; Fitness level = Average; Calculation method = Max Heart Rate (220 - Age). The corresponding output is Maximum Heart Rate: 190. A zone boundary expresses a percentage or reserve-based share of an estimated maximum.

Before relying on the result

  • Confirm the units, dates, rates and time periods entered.
  • Review which costs, measurements or assumptions are included and excluded.
  • Change one important input at a time to understand the result sensitivity.
