RIR/RPE Target Tool
Evaluate how challenging a set should have been
What this does
This tool evaluates how challenging a set should feel based on the weight lifted, reps performed, and your known 1RM. Perfect for calibrating your RPE perception or checking if you hit your intended intensity.
Example Use Case
Your estimated 1RM is 275 lbs. You just lifted 200 lbs for 8 reps.
- • Actual Intensity = 200 / 275 × 100 ≈ 72.7%
- • Looking at 8 reps column: 72.5% matches 3.0 RIR
- • This set should have felt like 3 RIR / RPE 7
💡 When to Use This
- • After a set: Check if you hit your intended RPE target
- • Learning RPE: Calibrate your perceived exertion with actual intensity
- • Form check: Verify if technique breakdown matches expected difficulty
