About this tool

What Bench Press Calculator - Find Your 1RM does

The Strength Level 1RM calculator estimates your one-rep max by entering the weight lifted and the number of repetitions completed. It supports bench press and other barbell lifts, and includes a built-in repetition-to-percentage table that lets you set training intensities as percentages of your calculated max. The result is a single estimated 1RM value, accompanied by a reference chart that maps common rep ranges to their corresponding percentages of that max. The site presents the calculator alongside broader fitness standards and a paper workout log for purchase, but the calculator itself runs free without requiring an account or payment.
