The Ultimate Guide to RPE Training
A comprehensive introduction to Rate of Perceived Exertion for beginners. Learn how to listen to your body and optimize your training.
Rate of Perceived Exertion (RPE) has revolutionized modern strength training. No longer are lifters bound strictly by arbitrary percentages of a 1-Rep Max (1RM) that might have been tested months ago. Instead, RPE allows for autoregulation—adjusting your training load based on your daily readiness.
What is RPE?
RPE is a subjective scale used to measure the intensity of your exercise. Originally developed by Gunnar Borg as a 6-20 scale for aerobic exercise, it was later adapted by powerlifting coach Mike Tuchscherer into a 1-10 scale specifically for strength training.
The RPE Scale Breakdown
Understanding the scale is the first step to mastering it. Here is the standard 1-10 RPE scale used in strength training:
| RPE Value | Description | Reps in Reserve (RIR) |
|---|---|---|
| 10 | Maximum effort. Could not do another rep or add more weight. | 0 |
| 9.5 | Could not do another rep, but could slightly increase weight. | 0.5 |
| 9 | Could do exactly 1 more rep with good form. | 1 |
| 8.5 | Could definitely do 1 more rep, maybe 2. | 1.5 |
| 8 | Could do exactly 2 more reps. | 2 |
| 7.5 | Could definitely do 2 more reps, maybe 3. | 2.5 |
| 7 | Could do 3 more reps. Speed is still very fast. | 3 |
| < 7 | Warm-up weights. Effort is very light and explosive. | 4+ |
Why Use RPE?
- Accounts for Daily Fluctuations: Sleep, nutrition, stress, and recovery all impact your strength. RPE adjusts for these variables automatically.
- Prevents Overtraining: By capping your effort at a specific RPE (e.g., RPE 8), you avoid burning out your Central Nervous System (CNS).
- Individualized Progression: You progress at your own pace. As you get stronger, the weight you use for a given RPE will naturally increase.
How to Implement RPE
When you see a program prescribed as:
Squat: 3 sets of 5 reps @ RPE 8This means you should select a weight that allows you to perform 5 reps, leaving exactly 2 reps in the tank (RPE 8).
If you are unsure of what weight to select, use our RPE Calculator to estimate your working sets based on your recent performance.
Step-by-Step Implementation
- Warm Up: Perform your standard warm-up routine.
- Assess Readiness: Pay attention to bar speed during your warm-up sets. If the bar moves fast, you might be able to go heavier today.
- Select Target Weight: Based on your warm-up and previous sessions, select a weight you believe will hit the target RPE.
- Perform Set: Execute the set with maximum intent.
- Evaluate RPE: Immediately after racking the bar, ask yourself: "How many more reps could I have done with good form?"
- Adjust: If you aimed for RPE 8 but it felt like RPE 9, drop the weight for your next set. If it felt like RPE 7, increase the weight.
Mastering RPE takes time and honesty. Don't let your ego dictate the numbers. Train hard, but train smart.
