Progressive Muscle Relaxation Guide

Tense for five, release for ten — and the body map lights up where you are, so you don't lose your place when your eyes are closed.

—

Don't tense so hard it hurts. Aim for "noticeably contracted" — about 70% of your max. Skip any group that aggravates an injury.

How to use it

Pick Full · 16 groups for the standard session (about 12 minutes) or Short · 4 groups for a quick reset (about 4 minutes).
Sit in a chair or lie down. Loosen tight clothes and remove shoes.
Press Start. The body map lights up the current group.
When it says Tense, contract the highlighted muscle group for 5 seconds (don't hold your breath).
When it says Release, let go fully for 10 seconds. Notice the difference.
Skip a group if it's uncomfortable or you're already relaxed there.

When to reach for it

Before sleep, when your body is tired but you can't drop off.
After a long day of holding tension in your jaw, shoulders or back.
During a high-anxiety moment when breathing alone isn't enough.
As a daily 10-minute practice to lower baseline tension.

Reading your results

There's no score. The result is what your body did next. If your shoulders sit a half-inch lower than when you started, that's the win. The body map's "done" groups help you see how far through you are when your eyes are closed.

What this actually does

Progressive Muscle Relaxation (PMR) was developed by Edmund Jacobson in the 1930s. The idea is simple: you cannot be fully tense and fully relaxed in the same muscle at the same time. By deliberately tensing a muscle and then releasing it, you give your nervous system a contrast — and the "release" half tends to drop below your usual resting tone. That contrast is the active ingredient.

Modern versions usually use 7- to 16-group sequences from feet to head. Going bottom-up follows the convention because legs often hold more tension than we realise; going top-down follows it because the face and jaw are where anxiety tends to show up first. Either works. The bigger predictor of benefit is whether you actually let go during the release phase — many people drop the count by half because they're still micro-tensing.

Who it's for

People whose anxiety lives in the body rather than in their head — neck pain, jaw clenching, restless legs, lower-back tightness. It's also helpful for people who find breath-only techniques too "airy"; the concrete cue of "curl your toes for five seconds" is easier to land than "breathe deeper". It is less useful for racing thoughts, which is what thought records are for.

If you have a recent injury, are pregnant, or have uncontrolled high blood pressure, skip the parts that aggravate you. Tensing should feel like effort, not strain. The Skip button is there for a reason.

Limitations

PMR doesn't directly touch anxious thoughts. It also doesn't replace movement — if your tension is from sitting at a desk all day, ten minutes of PMR is a nice top-up, but a five-minute walk is better medicine. Don't expect a single session to undo chronic tension; the literature shows cumulative benefit over 4–6 weeks of daily practice.

How to read your results

The "result" is mostly physical. If your breathing is slower and your shoulders are lower at the end than at the start, it worked. If you can't tell, try doing the short version once a day for a week and see if your evening tension baseline shifts. There is no app score; the score is whether you remember to do it tomorrow.

Common questions

Full vs Short — which should I pick? ▾

Full is the version studied in most of the trials and runs about 12 minutes. Short is for the times when you don't have 12 minutes — it focuses on the four groups that hold the most tension for most people (jaw, shoulders, lower back, calves) and finishes in about 4 minutes. Use Short for daily quick resets and Full for evenings when you actually have time to lie down.

I keep tensing too hard. ▾

Aim for about 70% of your maximum. The point is to create a contrast the nervous system can register, not to strain. If your face is red after the jaw clench or your arms are shaking after the fist, you're overdoing it. Drop the effort, not the count.

Should I hold my breath while tensing? ▾

No — that defeats half the purpose. Breathe normally throughout. If you find yourself holding your breath, exhale through the tense phase and inhale through the release. That's the version often called "relaxation breathing" and it stacks well with PMR.

Will I fall asleep during this? ▾

Maybe — and that's fine. If you fall asleep before the end, you've gotten the most useful possible result. Don't worry about finishing the sequence. If you want to stay awake for the full thing, sit in a chair rather than lying down.

What are the common mistakes when using Progressive Muscle Relaxation Guide?

Most common mistakes come down to four habits: entering 20 when the field expects 0.2 because the field is a percentage; leaving a field blank and accepting the default without checking what it stands for; changing one input and reading a result that was calculated before the change; and quoting the output as an exact figure when the page describes it as a reference estimate. Press calculate again after any edit, and treat the number as a reference point rather than a final answer.
