Relative Intensity vs. Absolute Intensity

While **Absolute Intensity** refers directly to the percentage of your 1-Rep Max, **Relative Intensity** measures how difficult a set is relative to your limit performance for that specific rep range. A set of 5 reps at RPE 9 is functionally 83% relative intensity, ensuring you maintain optimal fatigue management during periodized loading.
