What is RPE?

Hello! Today I’ll explain an important strength training concept: the RPE scale – what it means, where it comes from, and how you use it for your training.

RPE stands for ‘Rate of Perceived Exertion’, or your rating of how hard something feels. It comes from sports science and was used to subjectively gauge training intensity.

In strength training, RPE tells you how close a set was to your current limit. The scale usually runs from 1 to 10.

RPE 10 means you couldn’t do another rep. At RPE 9, you could have done one more; at RPE 8, two more – and so on.

This rating helps you control your training intensity, since it works regardless of the weight used.

Especially on days when you feel tired or stressed, a weight can feel heavier. RPE helps you still set the right training stimulus.

If you regularly train with a target RPE, e.g. RPE 8, you stay close to your limit without exceeding it – ideal for safe progress.

You also avoid unnecessary overuse, because you learn to tell when a set is too heavy or when to leave reps in reserve.

Treeceps uses this too: your actual set performance affects how many Gains Hearts you earn and how much your muscle groups are taxed.

This load also goes into the calculation of your current muscle fatigue – the 0 to 1 value showing how recovered or fatigued a muscle is.

If you use RPE consciously, you help Treeceps plan your training even more precisely and ensure optimal recovery between sessions.

Summary: RPE helps you steer your training by feel and ability. With practice, RPE becomes one of your best tools for long-term success!
