Last updated: 6 September 2026.

The bench press calculator on this site provides estimated one-rep-max values from a weight and a repetition count. The estimates use published prediction formulas. They are not a substitute for coaching, medical advice, or a supervised strength test.

You use the site at your own risk. Strength training can cause injury. Do not attempt a true one-rep max if you are untrained, injured, or unsupervised.

The site is provided as-is, without warranties of accuracy or fitness for a particular purpose.
