    Answer

    Lifting 55 kg for 12 reps gives an estimated one rep max of
    77 kg

    Epley formula · an estimate from a set taken close to failure; accuracy depends on the exercise and the person and drops as reps grow

    At 12 reps the formulas drift apart — the others give 70.5–79.4 kg: treat 77 kg as a rough guide.

    55 × (1 + 12 ÷ 30) = 77 kg
