Estimated one-rep max: about 164 kg (360 lb). The five formulas span 158–169 kg, so treat it as a range rather than a number.

So is 164 kg a good bench press?
If that lift is a bench press, 164 kg (360 lb) puts a man at 82.5–87.5 kg bodyweight at the 91st 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.

145 kg × 4 — common questions
What is my one-rep max if I lift 145 kg for 4 reps?
About 164 kg (360 lb), taken as the mean of the Epley, Brzycki, Lombardi, O'Conner and Mayhew formulas. Individually they give 158 to 169 kg, so the range is the honest answer.
Is 164 kg a good bench press?
If the lift is a bench press, 164 kg (360 lb) puts a man at 82.5–87.5 kg bodyweight at the 91st 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 65 kg × 5, 90 kg × 5, 114 kg × 3, 131 kg × 2, 147 kg × 1, then the working single at 164 kg. It is a conventional ladder rather than a rule; the test is that the last warm-up still moves fast.
