Practical Example

Let’s say you lift 70 kg for 8 repetitions.

Using the Epley formula: 1RM=Weight×(1+Reps30)\text{1RM} = \text{Weight} \times \left(1 + \frac{\text{Reps}}{30}\right)1RM=Weight×(1+30Reps​) 1RM=70×(1+830)=70×1.2667≈88.67 kg\text{1RM} = 70 \times \left(1 + \frac{8}{30}\right) = 70 \times 1.2667 \approx 88.67 \text{ kg}1RM=70×(1+308​)=70×1.2667≈88.67 kg

The calculator instantly provides this estimated 1RM, helping you plan future sets and track your strength improvement safely.
