RPE Scale: Interactive 1-10 Rate of Perceived Exertion Chart

What is the RPE scale?

The RPE scale is a way to put a number on how hard your body feels it is working. RPE stands for rate of perceived exertion, sometimes called rating of perceived exertion. You don't need a watch or a heart-rate strap, just an honest read of your breathing, your muscles and how tired you feel.

CDC describes this kind of relative intensity on a scale of 0 to 10, where 0 is the effort of sitting and 10 is maximal effort. Because it is relative, an activity that is vigorous for one person may be only moderate for someone fitter.

This tool uses ViveLab's own 0-10 wording. Tap a number to see its description, intensity band and talk-test cue.

RPE scale 1-10 chart

Here is the full rpe chart the tool uses, with 0 added for rest:

Rating	Label	What it feels like
0	Rest	No effort, sitting or lying still.
1	Very easy	Barely any effort; breathing normal.
2	Easy	Light effort you could keep up all day.
3	Light	Breathing a little deeper; easy to talk.
4	Light to moderate	Starting to warm up; you can still talk easily.
5	Moderate	Breathing harder; you can talk but not sing.
6	Moderate to hard	Noticeably working; talking in full sentences takes effort.
7	Vigorous	Hard work; you can say only a few words without pausing for breath.
8	Very hard	Very hard; speaking is difficult.
9	Near maximal	You can keep this up only for a very short time.
10	Maximal	All-out effort; you can't continue.

The tool groups ratings into four bands: 1-4 light, 5-6 moderate, 7-8 vigorous and 9-10 near maximal. The moderate and vigorous bands follow the US guidance described below. The light and near-maximal labels are ViveLab's own groupings to make the ends of the scale easier to read.

How do you use the RPE scale?

Warm up first, then rate the effort once you have been going for a few minutes. Think about your whole body, not just burning legs or a racing heart.

Ask yourself which description matches best and pick that number. If you are between two, choose the lower one and check again a few minutes later. Ratings drift as you tire, so re-rating during a long session is normal.

What RPE should you train at?

For general health, the Physical Activity Guidelines for Americans say that on a 0-10 scale, moderate-intensity activity is a 5 or 6. Vigorous-intensity activity begins at a level of 7 or 8.

The same guidelines advise adults to do 150-300 minutes a week of moderate-intensity activity, or 75-150 minutes of vigorous-intensity activity, or an equivalent mix. So a brisk walk that sits at 5 or 6 on the RPE scale counts toward the moderate total.

The guidelines also note that relative intensity is a better guide than absolute intensity for older adults. People who have been very inactive can use it to judge their effort as they build up.

The talk test

CDC's page on measuring physical activity intensity gives a simple rule of thumb. A person doing moderate-intensity activity can talk, but not sing. A person doing vigorous-intensity activity cannot say more than a few words without pausing for a breath.

That is why the tool shows a talk-test cue with each rating. If you rated yourself a 4 but can't finish a sentence, your rating is probably too low.

RPE vs heart rate

Heart rate measures what your heart is doing. Perceived exertion measures how hard the work feels to you. They usually rise together, and the US guidelines describe relative intensity as paying attention to how activity affects your heart rate and breathing.

A perceived exertion scale needs no equipment and works on any activity, which makes it handy when you have no monitor. The guidelines even say that during pregnancy, perceived exertion is often a better indicator of intensity than heart rate.

Using RPE at work

The same idea helps on the job. Asking workers "how hard does this task feel, 0 to 10?" is a quick way to find tasks that deserve a closer look. Work task mode lets you name a task and record a rating.

At 7 or above, the tool suggests checking the task with a formal method. This is a prompt to look further, not an official threshold. Good next steps include:

• For lifting and lowering, work out the recommended weight limit with our NIOSH lifting equation calculator.
• For awkward whole-body postures, score the task with a free REBA assessment.
• For repetitive hand and wrist work, read how the Strain Index rates distal upper-limb risk.

RPE vs the Borg scale

The best-known perceived exertion scales are the Borg RPE 6-20 scale and the Borg CR10 scale. Both are copyrighted and have their own wording, so this tool does not reproduce them. To see how they work and how they differ from a plain 0-10 scale, read our guide to the Borg scale.

What are the limits of the RPE scale?

RPE is subjective. Mood, heat, sleep, motivation and experience all shift how hard something feels, so two people can rate the same effort differently. Use your ratings to compare your own sessions over time, not to compare yourself with others.

This page is general information about exercise intensity, not medical advice. If you have a health condition, are pregnant or are starting a new exercise programme, talk to a health professional about what intensity suits you. Stop and seek help if you feel chest pain, dizziness or unusual shortness of breath.
