Individual results vary based on genetics, training history, and other factors. Use these as general guidelines, not absolute measures.
RPE Prescriptions
Recommended sets and rep ranges based on your target intensity level.
What is RPE?
RPE (Rate of Perceived Exertion) is a 1-10 scale measuring how hard a set feels. It's based on Reps in Reserve (RIR) - how many more reps you could have done. For example, RPE 8 means you stopped with 2 reps left before failure.
| RPE | Sets | Rep Range | Training Zone |
|---|---|---|---|
55 RIR | 3 | 15-20 | Endurance |
64 RIR | 4 | 12-15 | Volume |
73 RIR | 4 | 10-12 | Hypertrophy |
82 RIR | 3 | 8-10 | Hypertrophy |
91 RIR | 3 | 6-8 | High Intensity |
100 RIR | 2 | 4-6 | Max |
Training Zone Guide
Focus on form and movement patterns. Low fatigue, skill development.
Build work capacity. Higher rep counts to accumulate training volume.
Primary strength adaptation zone. Challenging but sustainable.
Heavy work for strength gains. Requires adequate recovery.
Very heavy loads. Use sparingly for peaking or testing.
All-out effort. Save for PRs or competition prep.

Working Weight by RPE
Enter your 1RM to see recommended weights at each RPE level.
How it works:
- New lifters: Starting weight = bodyweight × 0.2 × 0.5
- Experienced lifters: Working weight = 1RM × RPE percentage (e.g., RPE 8 = 76% of 1RM)
- Warmups: 1-2 progressively heavier sets before working sets
