One Rep Max Calculator

Enter the number of repetitions you could perform to or very near muscular failure with this weight. If you stopped the set with several repetitions still in reserve, the estimated 1RM may be too low. Up to 10 reps — prediction uncertainty increases as the repetition count rises.

Estimate your one-rep max for bench press, back squat, or deadlift using the Epley and Brzycki formulas.
