45 kg × 2 — common questions
What is my one-rep max if I lift 45 kg for 2 reps?
About 48 kg (106 lb), taken as the mean of the Epley, Brzycki, Lombardi, O'Conner and Mayhew formulas. Individually they give 46 to 50 kg, so the range is the honest answer.
Is 48 kg a good bench press?
If the lift is a bench press, 48 kg (106 lb) puts a man at 82.5–87.5 kg bodyweight at the 1st 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 19 kg × 5, 26 kg × 5, 34 kg × 3, 38 kg × 2, 43 kg × 1, then the working single at 48 kg. It is a conventional ladder rather than a rule; the test is that the last warm-up still moves fast.
