How to use the RPE Chart
Follow these simple steps to find your exact target weight percentage.
Step 1: Target Reps
Locate your target reps for the set on the top row of the chart. For example, if you are doing sets of 5, find the number 5.
Step 2: Target RPE
Find your assigned RPE (Rate of Perceived Exertion) on the left column. If your program says RPE 8, look down the left side.
Step 3: Find Percentage
Follow the row and column to their intersection. This is the exact percentage of your 1-Rep Max you should lift for that set.
The Science of RPE
The Rate of Perceived Exertion (RPE) scale, popularized in powerlifting by Mike Tuchscherer (Reactive Training Systems), assigns a numerical value to the difficulty of a set.
Instead of blindly following a static percentage that doesn't account for daily fatigue, stress, or recovery, RPE allows you to auto-regulate. A 5 rep set at RPE 8 should feel like you have exactly 2 reps left in the tank. The RPE chart translates this subjective feeling into an objective percentage of your 1RM, assuming average lifter efficiency.
Reps in Reserve (RIR) = 10 - RPE
