What is the one rep max for 230 kg × 8 reps?

Answer

Lifting 230 kg for 8 reps gives an estimated one rep max of
291.3 kg

A set of 8 reps at 230 kg is

78.9%

of your estimated one rep max

Note: this is an estimate, not a tested max. Rep-based formulas are closest at 2–6 reps and drift further apart as the set gets longer. Warm up and use a spotter before attempting a true single.

How to Calculate One Rep Max

Epley Formula: 1RM = weight × (1 + reps ÷ 30)

The Epley formula assumes that every extra repetition you can complete corresponds to roughly 3.33% more weight on the bar. Put your set into it:

230 × (1 + 8 ÷ 30)

≈

230 × 1.2667

≈

291.3 kg
