What is the one rep max for 142.5 kg × 3 reps?

Answer

Lifting 142.5 kg for 3 reps gives an estimated one rep max of
156.8 kg

A set of 3 reps at 142.5 kg is

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:

142.5 × (1 + 3 ÷ 30)

=

142.5 × 1.1

≈

156.8 kg
