135 kg for 12 reps
Estimated one-rep max: about 183 kg (403 lb). The five formulas span 173–194 kg, so treat it as a range rather than a number.

Mean of five published formulas. Range 173–194 kg — above ten reps every formula is extrapolating, so this is a rough guide only.

So is 183 kg a good bench press?
If that lift is a bench press, 183 kg (403 lb) puts a man at 82.5–87.5 kg bodyweight at the 98th 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.

135 kg × 12 — common questions
What is my one-rep max if I lift 135 kg for 12 reps?
About 183 kg (403 lb), taken as the mean of the Epley, Brzycki, Lombardi, O'Conner and Mayhew formulas. Individually they give 173 to 194 kg, so the range is the honest answer — and above ten reps all five are extrapolating past the data they were fitted on.
Is 183 kg a good bench press?
If the lift is a bench press, 183 kg (403 lb) puts a man at 82.5–87.5 kg bodyweight at the 98th 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 73 kg × 5, 101 kg × 5, 128 kg × 3, 146 kg × 2, 165 kg × 1, then the working single at 183 kg. It is a conventional ladder rather than a rule; the test is that the last warm-up still moves fast.
