About

This free bench press calculator estimates your one-rep max (1RM), the heaviest weight you can press once with good form. Enter the total weight you lifted and the repetitions (reps) you completed. The main estimate uses the Epley formula, with a Brzycki result for comparison.

This is an independent tool site. Calculations run in your browser. Use the estimates as training references, not as proof that you can lift a weight. They do not replace coaching or medical advice.
