What is the one rep max for 175 lbs × 12 reps?

Answer

Lifting 175 lbs for 12 reps gives an estimated one rep max of
245 lbs

A set of 12 reps at 175 lbs is

71.4%

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:

175 × (1 + 12 ÷ 30)

=

175 × 1.4

=

245 lbs
