Session RPE
Session RPE estimates internal load by multiplying perceived exertion (0–10) by workout duration in minutes.
Session RPE multiplies how hard a workout felt (0–10) by duration in minutes to estimate internal training load. It is simple, cheap, and works across modalities when heart rate is unreliable.
Log RPE within 30 minutes while the session is fresh.
Common questions
-
How is session RPE calculated?
Multiply your 0–10 session difficulty rating by duration in minutes. A 45-minute workout rated 7 yields a session load of 315 arbitrary units.
-
Should RPE include warm-up?
Most athletes rate the main work block only, but stay consistent week to week so trends stay comparable.
