115 kg for 12 reps
Estimated one-rep max: about 156 kg (344 lb). The five formulas span 147–166 kg, so treat it as a range rather than a number.

Mean of five published formulas. Range 147–166 kg — above ten reps every formula is extrapolating, so this is a rough guide only.

So is 156 kg a good bench press?
If that lift is a bench press, 156 kg (344 lb) puts a man at 82.5–87.5 kg bodyweight at the 87th percentile of 29,914 judged competition benches — elite. For a squat or a deadlift the same weight ranks lower, because those lifts are heavier for everyone.

115 kg × 12 — common questions
What is my one-rep max if I lift 115 kg for 12 reps?
About 156 kg (344 lb), taken as the mean of the Epley, Brzycki, Lombardi, O'Conner and Mayhew formulas. Individually they give 147 to 166 kg, so the range is the honest answer — and above ten reps all five are extrapolating past the data they were fitted on.
Is 156 kg a good bench press?
If the lift is a bench press, 156 kg (344 lb) puts a man at 82.5–87.5 kg bodyweight at the 87th percentile of 29,914 judged competition benches — elite. That population all competed, so it is stronger than a gym average.
What should I warm up with?
The ramp below runs 62 kg × 5, 86 kg × 5, 109 kg × 3, 125 kg × 2, 140 kg × 1, then the working single at 156 kg. It is a conventional ladder rather than a rule; the test is that the last warm-up still moves fast.
