FAQ

Questions One-Rep Max Calculator owners ask.

  • 01

    How accurate are these 1RM estimates?

    Estimates are most accurate when repetitions are 12 or fewer. For higher rep counts, the validate_lift_integrity capability can flag if the estimation may be unreliable.

  • 02

    Can I use this for both kilograms and pounds?

    Yes, all capabilities support both 'kg' and 'lbs' units.

  • 03

    What is RPE?

    RPE stands for Rate of Perceived Exertion. You can use get_rpe_equivalence to estimate how much effort a specific weight and repetition count requires on a standard scale.
