What is the one rep max for 495 lbs × 10 reps?

Answer

Lifting 495 lbs for 10 reps gives an estimated one rep max of
660 lbs

A set of 10 reps at 495 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:

495 × (1 + 10 ÷ 30)

=

495 × 1.3333

=

660 lbs
