RPE means Rate of Perceived Exertion.
It is a simple way to describe how difficult a set feels.
RPE 6
You could probably perform around 4 more good repetitions.
RPE 7
Around 3 more.
RPE 8
Around 2 more.
RPE 9
Around 1 more.
RPE 10
No more good repetitions are available.
Why Use RPE?
It helps you adjust training based on how you feel that day.
Sleep, stress, nutrition and fatigue can affect performance.
Example
If your program says to perform a set around RPE 8 but you slept badly and the normal weight feels much harder, you may reduce the weight.
Key Takeaways
- RPE is not about making every workout maximally difficult.
- It is about managing effort intelligently.
