How does the Bench Press Calculator work?

Accepted Answer

Epley formula: 1RM = weight × (1 + reps/30) Then: Brzycki formula: 1RM = weight × (36 / (37 − reps)) Then: More accurate with lower rep ranges (3–10 reps) — above 15 reps, accuracy decreases Then: Percentage charts then help plan training loads (e.g., 80% 1RM for hypertrophy).
