145 kg for 8 reps
Estimated one-rep max: about 180 kg (397 lb). The five formulas span 174–184 kg, so treat it as a range rather than a number.

So is 180 kg a good bench press?
If that lift is a bench press, 180 kg (397 lb) puts a man at 82.5–87.5 kg bodyweight at the 97th 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.

145 kg × 8 — common questions
What is my one-rep max if I lift 145 kg for 8 reps?
About 180 kg (397 lb), taken as the mean of the Epley, Brzycki, Lombardi, O'Conner and Mayhew formulas. Individually they give 174 to 184 kg, so the range is the honest answer.
Is 180 kg a good bench press?
If the lift is a bench press, 180 kg (397 lb) puts a man at 82.5–87.5 kg bodyweight at the 97th 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 72 kg × 5, 99 kg × 5, 126 kg × 3, 144 kg × 2, 162 kg × 1, then the working single at 180 kg. It is a conventional ladder rather than a rule; the test is that the last warm-up still moves fast.
