Terms of use

Last updated November 11, 2026.

Who provides TrainSums

TrainSums is provided by AdModifier LLC ("we", "us"). Its pages and, once live, its calculators are free to use. By using them you agree to these terms with AdModifier LLC.

Estimates, not advice

TrainSums results are estimates for planning training. A result is only as good as the numbers you enter and the formula it states, and formulas can differ from a tested max. They are not coaching, medical or professional advice. Lifting heavy weights carries a risk of injury: use safe equipment, a spotter or safety bars, and stop when something hurts.

Rules and tables change

Scoring coefficients, federation rules and test tables are revised from time to time. Each calculator will name the version it uses; we are not responsible for decisions based on a version that has since changed.

As it is

The site and calculators are provided as they are, without any promise that a result suits a particular purpose.

Copying

The text, examples and code of this site are ours. You may link to any page and quote short parts with a link. Please do not copy or republish whole pages, calculators or the design. Open-source parts keep their own licenses (see licenses).

Changes

We may update these terms; the version on this page is the current one. Questions: hello@trainsums.com
