RPE is a method to give a subjective measurement of how difficult any given set was. This is often useful as your bodies ability to perform is not consistent and RPE can give a good indicator of how you are performing on a given day.

The main draw back with this method is the fact that it is subjective, which means there is room for error.

To help you be more consistent with your RPE values here is a basic description of what each number means:

• 10: Maximal effort
• 9.5: Maybe could of done one more rep
• 9: Definitely could do one more rep
• 8.5: Maybe could do two more reps
• 8: Definitely could do two more reps
• 7.5: Maybe could of done three more reps
• 7: Fairly easy with quick speed
• 6.5: Borderline warmup set
