WHITELIGHTS

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

One-rep max

290 kg for 12 reps

Estimated one-rep max: about 393 kg (866 lb). The five formulas span 372–418 kg, so treat it as a range rather than a number.

Estimated one-rep max

393 kg

Mean of five published formulas. Range 372418 kg — above ten reps every formula is extrapolating, so this is a rough guide only.

So is 393 kg a good bench press?

If that lift is a bench press, 393 kg (866 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.

290 kg × 12 — common questions

What is my one-rep max if I lift 290 kg for 12 reps?

About 393 kg (866 lb), taken as the mean of the Epley, Brzycki, Lombardi, O'Conner and Mayhew formulas. Individually they give 372 to 418 kg, so the range is the honest answer — and above ten reps all five are extrapolating past the data they were fitted on.

Is 393 kg a good bench press?

If the lift is a bench press, 393 kg (866 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 157 kg × 5, 216 kg × 5, 275 kg × 3, 314 kg × 2, 354 kg × 1, then the working single at 393 kg. It is a conventional ladder rather than a rule; the test is that the last warm-up still moves fast.
