What is the one rep max for 375 lbs × 10 reps?

Answer

Lifting 375 lbs for 10 reps gives an estimated one rep max of
500 lbs

A set of 10 reps at 375 lbs is

75%

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:

375 × (1 + 10 ÷ 30)

=

375 × 1.3333

=

500 lbs
