Terms of use

Last updated: 2026-10-30

Using the site

OneRepMax HQ is provided free of charge. You may use the calculators and content for personal and coaching purposes.

Estimates, not advice

All results are estimates based on general formulas and may not reflect what you can safely lift. The site does not provide medical, physiotherapy or personal training advice. Strength training carries a risk of injury; you are responsible for lifting within your abilities, using appropriate safety equipment and seeking professional advice where needed.

No warranty

The site is provided "as is". We make reasonable efforts to keep the calculators accurate but do not guarantee that they are free of errors. To the extent permitted by law, we are not liable for any loss or injury arising from use of the site.

Links and advertising

The site may show advertising and contain links, including affiliate links, to third-party websites. We are not responsible for their content or practices.
