105 kg for 8 reps
Estimated one-rep max: about 130 kg (287 lb). The five formulas span 126–133 kg, so treat it as a range rather than a number.

So is 130 kg a good bench press?
If that lift is a bench press, 130 kg (287 lb) puts a man at 82.5–87.5 kg bodyweight at the 58th percentile of 29,914 judged competition benches — advanced. For a squat or a deadlift the same weight ranks lower, because those lifts are heavier for everyone.

105 kg × 8 — common questions
What is my one-rep max if I lift 105 kg for 8 reps?
About 130 kg (287 lb), taken as the mean of the Epley, Brzycki, Lombardi, O'Conner and Mayhew formulas. Individually they give 126 to 133 kg, so the range is the honest answer.
Is 130 kg a good bench press?
If the lift is a bench press, 130 kg (287 lb) puts a man at 82.5–87.5 kg bodyweight at the 58th percentile of 29,914 judged competition benches — advanced. That population all competed, so it is stronger than a gym average.
What should I warm up with?
The ramp below runs 52 kg × 5, 72 kg × 5, 91 kg × 3, 104 kg × 2, 117 kg × 1, then the working single at 130 kg. It is a conventional ladder rather than a rule; the test is that the last warm-up still moves fast.
