Epley: 1RM = weight × (1 + reps/30) — most widely used, works for 1–12 reps

Brzycki: 1RM = weight × 36 / (37 − reps) — more accurate for low-rep sets (1–5)

Lombardi: 1RM = weight × reps^0.10 — conservative estimate

Wilks score = (total lifted in kg) × coefficient(bodyweight) — gender and bodyweight adjusted strength comparison used in powerlifting
