WHITELIGHTS

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

One-rep max

125 kg for 11 reps

Estimated one-rep max: about 166 kg (365 lb). The five formulas span 159–173 kg, so treat it as a range rather than a number.

Estimated one-rep max

166 kg

Mean of five published formulas. Range 159173 kg — above ten reps every formula is extrapolating, so this is a rough guide only.

So is 166 kg a good bench press?

If that lift is a bench press, 166 kg (365 lb) puts a man at 82.5–87.5 kg bodyweight at the 92nd percentile of 29,914 judged competition benches — elite. 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.

125 kg × 11 — common questions

What is my one-rep max if I lift 125 kg for 11 reps?

About 166 kg (365 lb), taken as the mean of the Epley, Brzycki, Lombardi, O'Conner and Mayhew formulas. Individually they give 159 to 173 kg, so the range is the honest answer — and above ten reps all five are extrapolating past the data they were fitted on.

Is 166 kg a good bench press?

If the lift is a bench press, 166 kg (365 lb) puts a man at 82.5–87.5 kg bodyweight at the 92nd percentile of 29,914 judged competition benches — elite. That population all competed, so it is stronger than a gym average.

What should I warm up with?

The ramp below runs 66 kg × 5, 91 kg × 5, 116 kg × 3, 133 kg × 2, 149 kg × 1, then the working single at 166 kg. It is a conventional ladder rather than a rule; the test is that the last warm-up still moves fast.
