RPE / Percentage Chart

Rate of Perceived Exertion (RPE) is a subjective intensity scale that tells you how hard a set felt relative to your maximum capacity. Unlike fixed percentages, RPE auto-regulates to your daily readiness: if you are fatigued, you naturally use less weight at the same RPE, and if you feel strong, you push harder. This makes RPE-based training one of the most flexible and sustainable programming methods available.

The table below maps every combination of RPE and rep count to a percentage of your one-rep max. Enter your 1RM to see exact working weights for every cell. Use this chart to plan your training sessions or validate your in-session RPE ratings.

What Each RPE Level Means

10

Maximum effort. No reps left in the tank. True muscular failure.

9.5

Could maybe get 1 more rep, but not confident. Near-limit effort.

9

Could definitely get 1 more rep. Very hard but controlled.

8.5

Could get 1-2 more reps. Hard effort with a small buffer.

8

Could get 2 more reps. Challenging but sustainable across sets.

7.5

Could get 2-3 more reps. Moderate-to-hard effort.

7

Could get 3 more reps. Moderate effort, good for volume work.

6.5

Could get 3-4 more reps. Light-to-moderate working weight.

6

Could get 4 more reps. Warm-up territory or easy technique work.

Train with RPE in LiftProof

LiftProof tracks your RPE alongside weight and reps, then uses that data to auto-regulate your next session's programming.
