    What is the one rep max for 52.5 kg × 7 reps?

    Answer

    Lifting 52.5 kg for 7 reps gives an estimated one rep max of
    64.8 kg

    A set of 7 reps at 52.5 kg is

    81.1%

    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:

    52.5 × (1 + 7 ÷ 30)

    ≈

    52.5 × 1.2333

    ≈

    64.8 kg
