By accessing or using GymMaxCalculators.com (the "Site"), you agree to be bound by these Terms of Service. If you do not agree to these terms, please do not use the Site.
GymMaxCalculators.com provides free, browser-based fitness and strength calculators for informational and training-planning purposes. Calculators estimate values such as one-rep maxes, strength scores, and supplement dosing using published formulas, community-sourced benchmarks, and general research ranges, as described on each individual calculator page.
The Site does not provide medical, health, nutritional, or professional coaching advice. All content, calculations, and estimates are provided for general informational purposes only and are not a substitute for advice from a qualified physician, physical therapist, registered dietitian, certified strength coach, or other relevant professional. Always consult an appropriate professional before beginning a new exercise program, attempting a new maximal lift, changing your diet, or starting a new supplement.
Physical exercise, including strength training and testing maximal or near-maximal lifts, carries an inherent risk of injury. By using the Site's calculators to plan or estimate training loads, you acknowledge and accept this risk. You are solely responsible for using proper form, appropriate equipment (including spotters and safety bars where applicable), and sound judgment regarding your own physical condition and limitations.
The Site and its calculators are provided "as is" and "as available," without warranties of any kind, express or implied, including but not limited to accuracy, reliability, or fitness for a particular purpose. Calculated estimates may differ meaningfully from your actual performance or physiological response.
To the fullest extent permitted by law, GymMaxCalculators.com, its owners, operators, and affiliates shall not be liable for any direct, indirect, incidental, consequential, or special damages — including but not limited to personal injury, loss of data, or financial loss — arising out of or in connection with your use of, or inability to use, the Site or any calculator's output.
The Site displays advertisements served through Google AdSense and potentially other advertising networks. We are not responsible for the content of third-party advertisements, and their inclusion does not constitute an endorsement of any advertised product or service. See our Privacy Policy and Cookie Policy for details on advertising-related data practices.
The design, layout, original text content, and calculator logic on this Site are the property of GymMaxCalculators.com unless otherwise noted. You may use the calculators for personal, non-commercial purposes. You may not copy, reproduce, or redistribute the Site's underlying code or content for commercial purposes without permission.
You agree not to misuse the Site, including but not limited to: attempting to disrupt or overload the Site's infrastructure, scraping content at scale without permission, or using the Site for any unlawful purpose.
We may modify, suspend, or discontinue any part of the Site at any time without notice. We may also update these Terms of Service periodically; continued use of the Site after changes are posted constitutes your acceptance of the revised terms. Check the "last updated" date above for the most recent revision.
These Terms are governed by the laws of the United States and the state in which the Site operator resides, without regard to conflict-of-law principles, to the extent permitted by applicable law.
