Max Bench Calculator — Description
The Max Bench Calculator estimates your bench press one-rep max (1RM) from a weight-and-reps set. It supports several common formulas, including Epley, Brzycki, Lander, and Lombardi, and also shows percentage-based training weights for programming your workouts.
This calculator is useful for strength training, powerlifting, progressive overload planning, and estimating max strength without attempting a true one-rep max.
