Disclaimer

Last updated: August 2, 2026

Amatal is operated by Amatal LLC. This page sets out the most important limits on what our assessments can tell you and the risks involved in performing them. It is a summary written to be read — our full legal terms, including limitation of liability and acceptable use, are in the Terms of Service, which govern in the event of any conflict.

Physical Risk

Many assessments described on this site involve strenuous physical activity, including maximal or near-maximal effort. This carries inherent risk of injury, illness, or, in rare cases, serious harm or death.

Consult a physician before undertaking any fitness test or exercise program — particularly if you are new to exercise, are pregnant or postpartum, are recovering from injury or surgery, or have or may have any cardiovascular, respiratory, metabolic, or musculoskeletal condition.

Stop immediately if you experience pain, dizziness, chest discomfort, shortness of breath, or any other warning sign. You decide whether a test is appropriate for you, and you perform it entirely at your own risk. Amatal does not supervise or administer any assessment you choose to perform.

Not Medical Advice

Everything on this site — assessments, calculators, scoring tables, percentiles, classifications, derived metrics such as fitness age, and explanatory articles — is provided for general informational and educational purposes only.

This site is not a medical device and is not intended to diagnose, treat, cure, mitigate, or prevent any disease or condition. Results are not a substitute for evaluation by a physician, physical therapist, registered dietitian, or other licensed healthcare professional. Never disregard professional medical advice, or delay seeking it, because of something you read or calculated here.

If you believe you are experiencing a medical emergency, contact your local emergency services immediately.

Results Are Estimates

We score your inputs against reference data drawn from published research and normative tables, and we identify our sources on each assessment page. Every result is nonetheless an estimate:

  • Reference populations are specific. A norm derived from one group — by age, sex, training history, sport, occupation, geography, or era — may not describe you.
  • Predictive equations carry error. Estimates of maximal oxygen uptake, one-repetition maximum, body fat percentage, and similar values have known standard errors that apply to any individual result.
  • Field testing is sensitive to conditions. Timing method, surface, footwear, altitude, temperature, hydration, fatigue, technique, motivation, and measurement precision all affect outcomes.
  • Where published data is incomplete, we say so. Some ranges are interpolated or estimated rather than directly measured, and we flag those on the assessments where they occur.

Percentiles, tiers, and rankings describe how a measurement compares to a stated reference group. They are not a measure of your health, and a low result is not a diagnosis.

Not an Official Standard

Some assessments reference standards used by military, law enforcement, tactical, athletic, or occupational organizations. These are reproduced for informational and preparatory purposes only.

This site is not an official source for any such standard, is not affiliated with or endorsed by any of these organizations, and must not be used as the basis for selection, screening, hiring, promotion, medical clearance, return-to-play, return-to-duty, or any other decision affecting an individual.

Always refer to the current official publication of the governing organization, which may have changed since our source material was published.

Accuracy and Availability

We make substantial effort to source our standards accurately and to describe their limitations honestly. Even so, this site is provided "as is" and "as available," without warranties of any kind. We do not warrant that it will be uninterrupted or free of transcription or calculation errors, or that a published standard we rely upon is itself free of error or has not been superseded by newer research.

Minors

Some assessments reference standards developed for adults and are not appropriate for children or adolescents. Where an assessment states an age range, results outside that range may be unreliable or invalid. Anyone under 18 should use this site only with the involvement of a parent or guardian, and should not perform physical testing without appropriate adult supervision.

Commissioned Work

Amatal LLC builds assessments and calculators on commission for third parties. Those deliverables are built to the client's specification and supplied standards, carry no warranty of fitness for a particular purpose, and are not suitable for clinical, diagnostic, safety-critical, employment, or selection use unless separately agreed in writing. Full terms are in Section 11 of the Terms of Service.
