What does this tool do?
Session-RPE turns how hard a workout felt into a simple number by multiplying its duration by a 1–10 effort rating. Tracking that number week to week makes abrupt jumps in workload easier to spot.
The Formula
Session load = RPE × minutes; weekly load = session load × sessionsFrequently Asked Questions
What is a training load unit?
It is an arbitrary unit from RPE × minutes. A 60-minute session rated 7 adds 420 AU, which is useful for comparing your own weeks rather than for ranking athletes.
How fast should weekly load increase?
There is no universal rule. Keeping week-to-week changes modest and following planned recovery is more robust than chasing a fixed percentage.
