What is the one rep max for 235 kg × 9 reps?

Answer

Lifting 235 kg for 9 reps gives an estimated one rep max of
305.5 kg

A set of 9 reps at 235 kg is

76.9%

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:

235 × (1 + 9 ÷ 30)

=

235 × 1.3

=

305.5 kg
