Terms of use

By using benchprcalculator.com, you agree to these terms.

Estimates only

The calculator's estimates are based on formulas that have been published. Your actual one-rep max might be higher or lower. None of this is medical, coaching or training advice.

Lift safely

Heavy singles call for a warm up first, plus safety bars or someone to spot you. If anything hurts, stop. Any injury or health condition means you should speak with a doctor before testing your max.

No warranty

The site is provided as is, without any warranty. We work to confirm the formulas are correct, but injuries, losses or decisions based on a result are not our responsibility.

Using the site

Feel free to share links to your results and to use the calculator. Please don't copy the whole site or pass it off as your own.

Changes

We may change these terms from time to time. Today's page content is what governs your use.
