Estimating your max bench press
Your one-rep max bench is the most you can press for a single rep. Testing it for real is risky without a spotter, so most lifters estimate it from a set they've already done. A hard set of 1 to 5 reps gives the most reliable estimate — the more reps, the more the estimate drifts.
Why six formulas
There's no single perfect 1RM formula, so this calculator runs six (Epley, Brzycki, Lombardi, O'Conner, Mayhew, Lander) and shows the average plus the spread. A tight spread means the formulas agree; a wide one means treat the number with caution.
The rep-max table
Below the estimate you get a full table — your 3-rep, 5-rep and 8-rep bench and so on, as weights and percentages — the fastest way to pick working weights for your next bench session.
