What is the one rep max for 205 kg × 5 reps?

Answer

Lifting 205 kg for 5 reps gives an estimated one rep max of
239.2 kg

A set of 5 reps at 205 kg is

85.7%

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:

205 × (1 + 5 ÷ 30)

≈

205 × 1.1667

≈

239.2 kg
