Terms of use

Last updated 17 October 2026

Using the site

FormFit is free to use for personal, non-commercial purposes. By using it you agree to these terms. If you don't agree, please don't use the site.

Not medical advice

Everything on FormFit is general information for healthy adults. It is not medical, nutritional or physiotherapy advice and does not replace a professional who knows your history. Read the full medical disclaimer.

Accuracy

Calculators use published formulas that produce estimates. Real people vary, sometimes by a lot. We work to keep pages accurate but make no guarantee that any result or statement is correct, complete or current.

Exercise at your own risk

Physical training carries a risk of injury. You are responsible for choosing loads you can handle safely, using spotters and safety equipment, and stopping if something hurts. FormFit is not liable for any injury, loss or damage arising from use of the site, to the extent the law allows.

The text, calculators and design of FormFit are owned by us. Photographs are used under the Unsplash licence. You may link to any page and quote short passages with a link back; please don't republish whole pages.

The site displays third-party advertising. We don't endorse advertised products, and any dealings you have with advertisers are between you and them.

Changes

We may update these terms. The date at the top of the page shows the latest version. Questions: devkhushii08@gmail.com.
