So is 183 lb a good bench press?
If that lift is a bench press, 183 lb (83 kg) puts a man at 82.5–87.5 kg bodyweight at the 6th percentile of 29,914 judged competition benches — novice. For a squat or a deadlift the same weight ranks lower, because those lifts are heavier for everyone.

135 lb × 12 — common questions
What is my one-rep max if I lift 135 lb for 12 reps?
About 183 lb (83 kg), taken as the mean of the Epley, Brzycki, Lombardi, O'Conner and Mayhew formulas. Individually they give 173 to 194 lb, so the range is the honest answer — and above ten reps all five are extrapolating past the data they were fitted on.
Is 183 lb a good bench press?
If the lift is a bench press, 183 lb (83 kg) puts a man at 82.5–87.5 kg bodyweight at the 6th percentile of 29,914 judged competition benches — novice. That population all competed, so it is stronger than a gym average.
What should I warm up with?
The ramp below runs 73 lb × 5, 101 lb × 5, 128 lb × 3, 146 lb × 2, 165 lb × 1, then the working single at 183 lb. It is a conventional ladder rather than a rule; the test is that the last warm-up still moves fast.
