1 Rep Max Calculator

Calculate your 1 Rep Max quickly and accurately with this tool

Bench, Squat, and Deadlift are the 3 exercises I used for building this tool. Simply because I was a competitive powerlifter and used this tool to build programs.

But any exercise will work here! Don’t need to find your 1RM bench? Want to find your 1RM incline instead? Use those weights and reps in any of the exercise sections below. The calculations will work for any exercise!
