This RPE calculator helps you estimate the maximum weight you can lift for a certain number of repetitions, based on your Rate of Perceived Exertion.

## RPE Calculator

### How to Use the RPE Calculator

Enter the weight you lifted, the number of reps you performed, and the RPE rating for the set. RPE stands for “Rate of Perceived Exertion” and ranges from 6 to 10. After filling in the details, click the “Calculate” button to see your estimated one-rep max (1RM).

### How It Calculates Results

This calculator estimates your 1RM by using the weight lifted, reps performed, and RPE rating. The formula applied is an approximation based on the relationship between these values. It assumes a linear relation between RPE and the maximum number of reps possible at a given weight.

### Limitations

The accuracy of the RPE calculator can be affected by several factors including your experience level, the exercise performed, and your energy level on the day. The calculated 1RM is an estimate and may not reflect your true maximum strength. For the best results, use the calculator consistently under similar conditions.
