Welcome to the VO2 Max Calculator at https://vo2max-calculator.com/.

These Terms and Conditions explain the rules for using our free online tool. By accessing or using the Site, you agree to follow these terms. If you do not agree, please stop using the VO2 Max Calculator right away.

1. Acceptance of Terms and Conditions

By visiting https://vo2max-calculator.com/ or using our VO2 Max Calculator, you accept these Terms and Conditions in full. We may update them at any time. Continued use after changes means you accept the new version. We recommend checking this page occasionally.

2. About the VO2 Max Calculator

The VO2 Max Calculator is an independent, free web-based tool that estimates your maximal oxygen uptake (VO2 max) using common public formulas. These include the Cooper 12-minute run test, Rockport 1-mile walk test, resting heart rate method, and other standard field tests.

It provides an estimated VO2 max value (in ml/kg/min), along with a general fitness level and percentile ranking based on age and gender. The tool is for informational and educational purposes only. It is not affiliated with, sponsored by, or endorsed by any fitness brands, labs, wearable companies, or organizations.

All results are estimates based on formulas and the information you enter. Actual VO2 max can only be accurately measured in a laboratory setting.

3. Use of the Service

You may use the VO2 Max Calculator for personal, non-commercial purposes only. The tool is provided free of charge.

You agree to:

  • Enter accurate information when using the calculator.
  • Use the results responsibly and not as a substitute for professional advice.
  • Not attempt to copy, modify, reverse-engineer, or interfere with the tool or website.

4. Medical and Fitness Disclaimer

Important: The VO2 Max Calculator and all information on this Site are for general educational purposes only. They do not provide medical advice, diagnosis, treatment, or personalized fitness recommendations.

VO2 max estimates can help you understand your aerobic fitness level, but they are not a complete picture of your health. Factors like age, training status, genetics, and medical conditions affect real results.

Before starting any new exercise program, changing your training intensity, or making health decisions based on these estimates, consult a qualified healthcare professional or doctor. Stop any physical test immediately if you feel chest pain, dizziness, shortness of breath, or other unusual symptoms.

We are not responsible for any health decisions you make using this tool.

5. Accuracy of Information and Calculations

We work hard to keep formulas and calculations up to date with widely accepted exercise science standards. However, we cannot guarantee that every result will be perfectly accurate for every person.

Real-world results may vary due to individual differences, testing conditions, equipment, or environmental factors. For the most reliable VO2 max measurement, seek professional lab testing.
