So is 343 kg a good bench press?

If that lift is a bench press, 343 kg (755 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.

270 kg × 9 — common questions

What is my one-rep max if I lift 270 kg for 9 reps?

About 343 kg (755 lb), taken as the mean of the Epley, Brzycki, Lombardi, O'Conner and Mayhew formulas. Individually they give 331 to 351 kg, so the range is the honest answer.

Is 343 kg a good bench press?

If the lift is a bench press, 343 kg (755 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 137 kg × 5, 188 kg × 5, 240 kg × 3, 274 kg × 2, 308 kg × 1, then the working single at 343 kg. It is a conventional ladder rather than a rule; the test is that the last warm-up still moves fast.
