Calculator
Turn a recent set into working weights
Use a recent honest set to estimate e1RM, then translate that into a working weight for the next target reps and RPE. Treat the number as a coaching starting point, not a tested max.
How to use the prescription
- Start the next session toward 238 for 3 reps at about RPE 8(2 reps in reserve).
- If warm-ups already feel heavier than expected, drop before the top set instead of chasing the estimate.
- Recalculate from a fresher logged set when technique, fatigue, or block phase changes the recent ceiling.
Why this matters
Strength coach e1RM load calculator
coaches need a fast way to turn a logged set into estimated max and practical working weights without opening a separate spreadsheet. This tool should help coaches make a clearer decision before they turn the draft into client programming.
Inputs this tool uses:
- Weight lifted
- Reps completed
- Set RPE
- Target reps
- Target RPE
Expected output: Estimated e1RM plus a suggested working weight for the chosen target reps and RPE.
You can use this page without the widget: write down those inputs, then treat the result as Estimated e1RM plus a suggested working weight for the chosen target reps and RPE.. The calculator above is optional.
