One Rep Max Calculator

Enter your strongest set and press 'CALCULATE ORM'. Rep range of the set needs to be between 1-6 for useful estimations.

Remember that each of these formulas just gives you an estimation based on the formulas by 'Eply', 'Brzycki' & 'Lander'.

To calculate the weight for barbell lifts enter a 0 for the bodyweight. For lifts where the bodyweight counts like dips & pull ups enter it correctly.
