155 kg for 12 reps
Estimated one-rep max: about 210 kg (463 lb). The five formulas span 199–223 kg, so treat it as a range rather than a number.

Mean of five published formulas. Range 199–223 kg — above ten reps every formula is extrapolating, so this is a rough guide only.

So is 210 kg a good bench press?
If that lift is a bench press, 210 kg (463 lb) puts a man at 82.5–87.5 kg bodyweight at the 99th percentile of 29,914 judged competition benches — world-class. For a squat or a deadlift the same weight ranks lower, because those lifts are heavier for everyone.

155 kg × 12 — common questions
What is my one-rep max if I lift 155 kg for 12 reps?
About 210 kg (463 lb), taken as the mean of the Epley, Brzycki, Lombardi, O'Conner and Mayhew formulas. Individually they give 199 to 223 kg, so the range is the honest answer — and above ten reps all five are extrapolating past the data they were fitted on.
Is 210 kg a good bench press?
If the lift is a bench press, 210 kg (463 lb) puts a man at 82.5–87.5 kg bodyweight at the 99th percentile of 29,914 judged competition benches — world-class. That population all competed, so it is stronger than a gym average.
What should I warm up with?
The ramp below runs 84 kg × 5, 116 kg × 5, 147 kg × 3, 168 kg × 2, 189 kg × 1, then the working single at 210 kg. It is a conventional ladder rather than a rule; the test is that the last warm-up still moves fast.
