Estimated one-rep max: about 133 kg (294 lb). The five formulas span 129–137 kg, so treat it as a range rather than a number.

So is 133 kg a good bench press?
If that lift is a bench press, 133 kg (294 lb) puts a man at 82.5–87.5 kg bodyweight at the 61st percentile of 29,914 judged competition benches — advanced. For a squat or a deadlift the same weight ranks lower, because those lifts are heavier for everyone.

105 kg × 9 — common questions
What is my one-rep max if I lift 105 kg for 9 reps?
About 133 kg (294 lb), taken as the mean of the Epley, Brzycki, Lombardi, O'Conner and Mayhew formulas. Individually they give 129 to 137 kg, so the range is the honest answer.
Is 133 kg a good bench press?
If the lift is a bench press, 133 kg (294 lb) puts a man at 82.5–87.5 kg bodyweight at the 61st percentile of 29,914 judged competition benches — advanced. That population all competed, so it is stronger than a gym average.
What should I warm up with?
The ramp below runs 53 kg × 5, 73 kg × 5, 93 kg × 3, 107 kg × 2, 120 kg × 1, then the working single at 133 kg. It is a conventional ladder rather than a rule; the test is that the last warm-up still moves fast.
