RPE Calculator FAQ
Answers to common questions about how to calculate RPE.
What is an RPE calculator?
It estimates your one-rep max and recommended training weights based on the weight, reps, and the effort (RPE) of your last set. Learn more
How accurate is Personal Calibration?
Personal calibration tailors the RPE chart to your training data, improving accuracy over generic tables and getting better as you add more sets.
Can I plan competition attempts?
Yes. Use Meet Day Planning to enter your opener and RPE to receive recommended 2nd and 3rd attempts with strategy notes.
How do I use RPE for training?
Rate your last set's difficulty from 6-10. RPE 6 = easy, RPE 8 = 2-3 reps left, RPE 10 = max effort. Use this to auto-calculate target weights. Beginner's guide
What's the difference between RPE and percentage?
RPE accounts for daily fluctuations in strength, fatigue, and form. Percentages assume you're always at 100% capacity, which isn't realistic. Read comparison
How many sets do I need for calibration?
Just 2-4 sets with different rep ranges. The system learns your strength curve pattern and improves accuracy with more data over time.
Does it support kg and lbs?
Yes, toggle units in the header at any time. All calculations and plate math automatically convert between systems.
How do backoff sets work?
Choose from percentage-based, RPE-based, or fatigue-based methods. The system auto-calculates appropriate weights and reps for your backoff work.
Can I share my workouts?
Yes! Generate shareable links with all your settings, or export PDF summaries. Perfect for coaches or training partners.
Do you store my data?
No. All data stays in your browser. Privacy-first by design - we never see or store your training information.
What if my RPE feels off?
RPE can vary day-to-day. Use the calibration feature to adjust for your current state, or manually override target weights when needed.
Is this better than 1RM calculators?
Yes. Traditional 1RM calculators use fixed formulas. This adapts to your individual strength patterns and accounts for daily variations in performance.
