RPE Calculator
This tool allows you to input your estimated (or confirmed) One Rep Max for any lift. Then, it creates a table showing the approximate weights that would be in the descending order of your Rate of Perceived Exertion. Keep in mind that this table is a guide, and your real world numbers may fluctuate depending on your strengths, weaknesses, and skill level. This tool currently only functions in US standard Pounds. Soon, it will function in both pounds and kilograms!
