What is the one rep max for 77.5 kg × 7 reps?

Answer

Lifting 77.5 kg for 7 reps gives an estimated one rep max of
95.6 kg

A set of 7 reps at 77.5 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:

77.5 × (1 + 7 ÷ 30)

≈

77.5 × 1.2333

≈

95.6 kg
