How it works

The converter uses a simplified RPE chart for single sets: higher RPE values correspond to higher percentages of 1RM. Values are approximations and assume sets taken close to failure.

How to interpret

Use this to translate RPE-based prescriptions into target loads or to estimate RPE from a known %1RM. Always adjust for your own response and context.
