RPE calculator
Turn an RPE into the load on the bar.
Enter your 1RM or a recent set and Adaptiv converts a target of reps and RPE into a prescribed load — the percentage of 1RM, the reps in reserve (RIR), and the full RPE chart behind it. It reads a sub-maximal set backwards into an estimated 1RM, which a max-effort calculator can't.

Your prescribed load will appear here.
Enter your 1RM or a recent set, choose a target of reps and RPE, then press Prescribe load.
One chart is a snapshot.
Adaptiv prescribes every set.
This tool reads the chart for one target. Inside Adaptiv, every set is prescribed by RPE and recalibrated session to session — the load floats with your logged effort, so the percentages always track your current strength.
