115 lb × 9 — common questions
What is my one-rep max if I lift 115 lb for 9 reps?
About 146 lb (66 kg), taken as the mean of the Epley, Brzycki, Lombardi, O'Conner and Mayhew formulas. Individually they give 141 to 150 lb, so the range is the honest answer.
Is 146 lb a good bench press?
If the lift is a bench press, 146 lb (66 kg) 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 58 lb × 5, 80 lb × 5, 102 lb × 3, 117 lb × 2, 131 lb × 1, then the working single at 146 lb. It is a conventional ladder rather than a rule; the test is that the last warm-up still moves fast.
