So is 373 lb a good bench press?
If that lift is a bench press, 373 lb (169 kg) puts a man at 82.5–87.5 kg bodyweight at the 94th 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.

275 lb × 12 — common questions
What is my one-rep max if I lift 275 lb for 12 reps?
About 373 lb (169 kg), taken as the mean of the Epley, Brzycki, Lombardi, O'Conner and Mayhew formulas. Individually they give 353 to 396 lb, so the range is the honest answer — and above ten reps all five are extrapolating past the data they were fitted on.
Is 373 lb a good bench press?
If the lift is a bench press, 373 lb (169 kg) puts a man at 82.5–87.5 kg bodyweight at the 94th 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 149 lb × 5, 205 lb × 5, 261 lb × 3, 298 lb × 2, 335 lb × 1, then the working single at 373 lb. It is a conventional ladder rather than a rule; the test is that the last warm-up still moves fast.
