What is the one rep max for 180 lbs × 11 reps?

Answer

Lifting 180 lbs for 11 reps gives an estimated one rep max of
246 lbs

A set of 11 reps at 180 lbs is

73.2%

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:

180 × (1 + 11 ÷ 30)

=

180 × 1.3667

=

246 lbs
