Formula Explanation

The calculator uses the Epley formula to estimate your one-rep max:

1RM = Weight × (1 + (Reps / 30))

This formula takes into account the weight lifted and the number of repetitions performed to estimate the maximum weight you can lift one time.

Working Principle

The Epley formula is a widely used method for estimating one-rep max. It assumes that as the number of repetitions increases, the weight that can be lifted decreases. The formula provides a good estimate for most lifters and is easy to use.
