Percentage Calculator

Turn your 1RM into a full training percentage table, or estimate %1RM from a set you already did.

Switch between “From 1RM” mode (enter your max, get a full percentage table) and “From a Set” mode (enter a weight and rep count, get an estimated %1RM) using the toggle above.

Don’t have a tested 1RM yet? Estimate one first with the One Rep Max Calculator.
