How It Works
We use a standardized RPE chart (like Reactive Training Systems) to estimate what percentage of your 1RM you just lifted.
Tips & Best Practices
- •RPE is useful because it auto-regulates. If you are tired, your RPE 8 weight will be lower, preventing burnout.
- •Be honest with yourself about how many reps you had left.
