WHITELIGHTS

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

One-rep max

120 kg for 12 reps

Estimated one-rep max: about 163 kg (359 lb). The five formulas span 154–173 kg, so treat it as a range rather than a number.

Estimated one-rep max

163 kg

Mean of five published formulas. Range 154173 kg — above ten reps every formula is extrapolating, so this is a rough guide only.

So is 163 kg a good bench press?

If that lift is a bench press, 163 kg (359 lb) puts a man at 82.5–87.5 kg bodyweight at the 91st 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.

120 kg × 12 — common questions

What is my one-rep max if I lift 120 kg for 12 reps?

About 163 kg (359 lb), taken as the mean of the Epley, Brzycki, Lombardi, O'Conner and Mayhew formulas. Individually they give 154 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 163 kg a good bench press?

If the lift is a bench press, 163 kg (359 lb) puts a man at 82.5–87.5 kg bodyweight at the 91st 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 65 kg × 5, 89 kg × 5, 114 kg × 3, 130 kg × 2, 146 kg × 1, then the working single at 163 kg. It is a conventional ladder rather than a rule; the test is that the last warm-up still moves fast.
