What is the one rep max for 60 lbs × 4 reps?

Answer

Lifting 60 lbs for 4 reps gives an estimated one rep max of
68 lbs

A set of 4 reps at 60 lbs is

88.2%

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:

60 × (1 + 4 ÷ 30)

≈

60 × 1.1333

≈

68 lbs
