What is the one rep max for 145 lbs × 2 reps?

Answer

Lifting 145 lbs for 2 reps gives an estimated one rep max of
154.7 lbs

A set of 2 reps at 145 lbs is

93.8%

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:

145 × (1 + 2 ÷ 30)

≈

145 × 1.0667

≈

154.7 lbs
