How to use it
- Enter planned reps and target RPE or RIR.
- Review converted effort/load guidance output.
- Apply output to set prescription and adjust based on execution.

The estimate updates from the values below. Use it as a clear starting point, then apply the context that matters to you.
Uses a simple Epley model: estimate load from e1RM, reps, and target RPE (via RIR), or estimate RPE from a completed set.
What to enter
- Use realistic effort ratings based on technical failure margin.
- Keep rep targets consistent when comparing week to week.
- Pair conversion with bar speed or execution notes for quality control.
How to read the result
- Treat output as guidance, then confirm with real set performance.
- If RPE drifts too high early, reduce load and preserve planned volume.
- If RPE is too low, increase load gradually to maintain training intent.
Worked example
Autoregulated loading during variable readiness
- Scenario
- Client arrives under-recovered but still needs productive session targets.
- Workflow
- Convert rep target plus effort target into adjusted loading guidance.
- Decision
- Preserve session intent while reducing overload risk on low-readiness days.

Frequently asked questions
What is the difference between RPE and RIR?
RIR is reps left in reserve, while RPE is a 1-10 effort scale often derived from that reserve.
Can this replace coaching judgment?
No. Use it to guide decisions, then validate with technique quality, fatigue, and session context.
Why does predicted load differ from last week?
Readiness and execution vary week to week. That variation is exactly why autoregulation tools are useful.
