So is 101 kg a good bench press?
If that lift is a bench press, 101 kg (224 lb) puts a man at 82.5–87.5 kg bodyweight at the 19th 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.

90 kg × 4 — common questions
What is my one-rep max if I lift 90 kg for 4 reps?
About 101 kg (224 lb), taken as the mean of the Epley, Brzycki, Lombardi, O'Conner and Mayhew formulas. Individually they give 98 to 105 kg, so the range is the honest answer.
Is 101 kg a good bench press?
If the lift is a bench press, 101 kg (224 lb) puts a man at 82.5–87.5 kg bodyweight at the 19th 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 41 kg × 5, 56 kg × 5, 71 kg × 3, 81 kg × 2, 91 kg × 1, then the working single at 101 kg. It is a conventional ladder rather than a rule; the test is that the last warm-up still moves fast.
