Estimated one-rep max: about 139 kg (306 lb). The five formulas span 135–143 kg, so treat it as a range rather than a number.

So is 139 kg a good bench press?
If that lift is a bench press, 139 kg (306 lb) puts a man at 82.5–87.5 kg bodyweight at the 68th 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.

120 kg × 5 — common questions
What is my one-rep max if I lift 120 kg for 5 reps?
About 139 kg (306 lb), taken as the mean of the Epley, Brzycki, Lombardi, O'Conner and Mayhew formulas. Individually they give 135 to 143 kg, so the range is the honest answer.
Is 139 kg a good bench press?
If the lift is a bench press, 139 kg (306 lb) puts a man at 82.5–87.5 kg bodyweight at the 68th 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 56 kg × 5, 76 kg × 5, 97 kg × 3, 111 kg × 2, 125 kg × 1, then the working single at 139 kg. It is a conventional ladder rather than a rule; the test is that the last warm-up still moves fast.
