Frequently Asked Questions

The Epley formula estimates your one-rep max (1RM) using the equation: 1RM = weight × (1 + 0.0333 × reps). It is commonly used for exercises like squat, bench press, and deadlift.

The Epley formula is most accurate for rep ranges between 1 and 12. Beyond 12 reps, the estimate becomes less reliable due to muscular endurance factors.

This calculator provides an estimate. Actual 1RM can vary based on factors like fatigue, technique, and training history. Use it as a guideline for training loads.
