One Rep Max for 105 kg × 10 reps
One Rep Max Calculator
What is the one rep max for 105 kg × 10 reps?
Answer
Lifting 105 kg for 10 reps gives an estimated one rep max of
140 kg
A set of 10 reps at 105 kg is
75%
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:
105 × (1 + 10 ÷ 30)
=105 × 1.3333
=140 kg
