Real judged lifts. Zero self-reported numbers. This is what strong actually is.

One-rep max

230 kg for 10 reps

Estimated one-rep max: about 298 kg (658 lb). The five formulas span 288–307 kg, so treat it as a range rather than a number.

So is 298 kg a good bench press?

If that lift is a bench press, 298 kg (658 lb) puts a man at 82.5–87.5 kg bodyweight at the 99th percentile of 29,914 judged competition benches — world-class. For a squat or a deadlift the same weight ranks lower, because those lifts are heavier for everyone.

A conventional ramp, not the ramp. Add or remove steps to taste — the point is to arrive warm and not tired.

230 kg × 10 — common questions

What is my one-rep max if I lift 230 kg for 10 reps?

About 298 kg (658 lb), taken as the mean of the Epley, Brzycki, Lombardi, O'Conner and Mayhew formulas. Individually they give 288 to 307 kg, so the range is the honest answer.

Is 298 kg a good bench press?

If the lift is a bench press, 298 kg (658 lb) puts a man at 82.5–87.5 kg bodyweight at the 99th percentile of 29,914 judged competition benches — world-class. That population all competed, so it is stronger than a gym average.

What should I warm up with?

The ramp below runs 119 kg × 5, 164 kg × 5, 209 kg × 3, 239 kg × 2, 268 kg × 1, then the working single at 298 kg. It is a conventional ladder rather than a rule; the test is that the last warm-up still moves fast.
