    What is the one rep max for 225 lbs × 3 reps?

    Answer

    Lifting 225 lbs for 3 reps gives an estimated one rep max of
    247.5 lbs

    A set of 3 reps at 225 lbs is

    90.9%

    of your estimated one rep max

    Note: this is an estimate, not a tested max. Rep-based formulas are closest at 2–6 reps and drift further apart as the set gets longer. Warm up and use a spotter before attempting a true single.

    How to Calculate One Rep Max

    Epley Formula: 1RM = weight × (1 + reps ÷ 30)

    The Epley formula assumes that every extra repetition you can complete corresponds to roughly 3.33% more weight on the bar. Put your set into it:

    225 × (1 + 3 ÷ 30)

    =

    225 × 1.1

    =

    247.5 lbs
