50 kg for 12 reps
Estimated one-rep max: about 68 kg (149 lb). The five formulas span 64–72 kg, so treat it as a range rather than a number.

So is 68 kg a good bench press?
If that lift is a bench press, 68 kg (149 lb) puts a man at 82.5–87.5 kg bodyweight at the 2nd 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.

50 kg × 12 — common questions
What is my one-rep max if I lift 50 kg for 12 reps?
About 68 kg (149 lb), taken as the mean of the Epley, Brzycki, Lombardi, O'Conner and Mayhew formulas. Individually they give 64 to 72 kg, so the range is the honest answer — and above ten reps all five are extrapolating past the data they were fitted on.
Is 68 kg a good bench press?
If the lift is a bench press, 68 kg (149 lb) puts a man at 82.5–87.5 kg bodyweight at the 2nd 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 27 kg × 5, 37 kg × 5, 47 kg × 3, 54 kg × 2, 61 kg × 1, then the working single at 68 kg. It is a conventional ladder rather than a rule; the test is that the last warm-up still moves fast.
