Using RPE

RPE in Strength Training: Why Beginners Misuse It (and How to Calibrate It)

On Iron Radio, hosts Coach Phil Stevens, Dr. Lonnie Lowery and Dr. Mike T. Nelson discuss rate of perceived exertion (RPE) and why it can be misapplied in strength training. They define RPE as a subjective intensity scale (including the Borg 6–20 scale) and contrast it with objective measures like heart rate and percentages of 1RM. Phil argues RPE requires calibration through experience and that newer lifters often avoid hard work because they don’t yet know what true maximal effort feels like, while “tough guys” may under-rate effort. The group recommends pairing RPE with objective targets, tracking output over time for patterns, using coaching to calibrate effort, and reserving true all-out attempts for the competition platform to reduce injury risk.
