Progressive Muscle Relaxation (PMR): A Technique for Anxiety and Tension

Quick answer: Progressive muscle relaxation (PMR) is a technique where you systematically tense and release muscle groups to reduce physical tension and anxiety. Developed by Edmund Jacobson in 1938, it has moderate research support for anxiety, tension headaches, and sleep problems. Sessions take 10 to 20 minutes. Beginners often use audio recordings. A 2008 meta-analysis by Manzoni and colleagues showed moderate anxiety reduction. Modern clinical protocols use a 7-muscle-group abbreviated version that takes 10 to 15 minutes, while the traditional 16-group protocol takes 20 to 45 minutes (Bernstein and Borkovec 1973). PMR is a support tool for anxiety management, not a standalone treatment for anxiety disorders.

What is Progressive Muscle Relaxation?

Progressive muscle relaxation (PMR) is a somatic (body-based) relaxation technique that uses the contrast between muscle tension and release to trigger a relaxation response. The method is straightforward and requires no equipment.

The core protocol:

Select a muscle group (e.g., dominant hand and forearm)
Tense that muscle group deliberately for 5 to 10 seconds, using 70 to 80 percent of maximum effort
Release the tension completely and rest for 20 to 30 seconds
Notice the contrast between the tension and the relaxed sensation
Move to the next muscle group and repeat

This tense-release cycle is repeated through all major muscle groups, either head-to-toe or toe-to-head, depending on the protocol version.

Key principles:

Deliberate tension: The contraction must be intentional and sustained; you are not exercising or stretching
Smooth release: Let go completely; do not gradually relax
Sensory awareness: The goal is to notice the feeling of relaxation, developing greater awareness of your body's tension baseline
Sequential progression: Working through muscles in order (head to feet, or feet to head) creates a systematic full-body effect

The technique is based on reciprocal inhibition, a principle from behavioral psychology: the parasympathetic relaxation response triggered by releasing muscles is incompatible with the sympathetic arousal of anxiety. By practicing muscle relaxation, you teach your nervous system to shift into a calm state.

Historical origins and development

Progressive muscle relaxation was developed by Edmund Jacobson, an American physician and physiologist, in 1938. Jacobson's landmark text, Progressive Relaxation: A Physiological and Clinical Investigation of Muscular States and Their Significance in Psychology and Medicine, presented a complete methodology based on the principle that mental tension accompanies muscle tension, and that reducing physical tension reduces psychological anxiety.

Jacobson's original protocol was comprehensive and time-intensive, involving 45 or more minutes, with very fine control over individual muscles. While powerful, the length and complexity limited clinical adoption.

In 1973, behavioral psychologists Albert Bernstein and Thomas Borkovec published an abbreviated version of PMR in their influential text Progressive Relaxation Training: A Manual for the Helping Professions. Bernstein and Borkovec condensed Jacobson's protocol into two versions:

16-muscle-group protocol: Traditional, detailed, takes 20 to 30 minutes
7-muscle-group protocol: Abbreviated, clinical, takes 10 to 15 minutes

The Bernstein and Borkovec abbreviation made PMR practical for routine clinical use, and these protocols remain the standard in research and therapeutic settings today.

Evidence: What the research shows

A 2008 meta-analysis by Manzoni and colleagues (Journal of Psychosomatic Research) evaluated 60 randomized controlled trials of PMR for anxiety. Key findings:

Overall effect size: Moderate anxiety reduction (Cohen's d = 0.70)
Comparison to controls: PMR outperformed waitlist controls across most studies
Specific applications with evidence:
Generalized anxiety disorder and trait anxiety: Moderate benefit
Tension headaches: Moderate benefit
Insomnia and sleep onset: Moderate benefit
Procedural anxiety (pre-surgery, medical procedures): Moderate benefit
Cancer-related anxiety: Moderate benefit

Other reviews and studies support these findings:

McCallie et al. (2006) reviewed PMR for anxiety in the American Journal of Psychiatry and concluded that PMR is an evidence-supported technique for reducing somatic tension and worry
Conrad and Roth (2007) examined PMR combined with slow breathing for anxiety and found the combination more effective than either alone
Pawlow and Jones (2002) studied PMR in both clinical and non-clinical populations and found sustained anxiety reduction with regular practice

Important caveat: The evidence is moderate, not strong. PMR is not equivalent to cognitive-behavioral therapy (CBT) or medication in treating anxiety disorders. It works best as part of a broader anxiety management strategy.

How Progressive Muscle Relaxation works: The mechanism

PMR operates through several complementary mechanisms in your nervous system and psychology:

1. Reciprocal inhibition (physiological antagonism)

The relaxation response (parasympathetic activation) is neurologically incompatible with the fight-flight response (sympathetic activation). By deliberately triggering muscle relaxation, you activate the parasympathetic nervous system, which directly inhibits the sympathetic arousal underlying anxiety.

2. Interoceptive awareness (body scanning)

PMR teaches you to notice subtle differences in muscle tension. Over repeated practice, you become more sensitive to early signs of tension, allowing you to intervene earlier before anxiety escalates (Mehling et al. 2009, interoceptive awareness and emotion regulation).

3. Parasympathetic activation

The vagus nerve, which controls parasympathetic functions (slow heart rate, deep breathing, digestion), is activated by sustained relaxation. The transition from tension to relaxation engages this calming pathway.

4. Cognitive reappraisal via body-based learning

As you experience the contrast between tension and relaxation repeatedly, your brain learns at a somatic level that physical relaxation is possible and safe. This implicit learning reduces the catastrophic thinking that sustains anxiety.

Traditional 16-group Progressive Muscle Relaxation protocol

The classic Bernstein and Borkovec 16-group protocol takes 20 to 30 minutes and is the research standard. It covers:

Dominant hand and forearm
Dominant upper arm
Non-dominant hand and forearm
Non-dominant upper arm
Forehead
Upper cheeks and nose
Lower cheeks and jaw
Neck and throat
Chest, shoulders, and upper back
Abdomen
Dominant thigh
Dominant calf and foot
Non-dominant thigh
Non-dominant calf and foot
Entire left side
Entire right side (or full-body scan as final integration)

Typical timing per group: 5 to 10 seconds of tension, 20 to 30 seconds of rest and noticing, then move to the next group without significant pause.

This comprehensive approach is ideal for in-depth relaxation and is commonly used in therapeutic settings, research studies, and recorded PMR programs.

Abbreviated 7-group Progressive Muscle Relaxation protocol (modern clinical version)

For practical use, Bernstein and Borkovec also developed a 7-group abbreviated version that retains effectiveness while taking only 10 to 15 minutes:

Arms: Tense both hands into fists, forearms flexed
Face: Tense forehead, eyes, nose, cheeks, and jaw simultaneously
Neck and shoulders: Tense neck and shoulder muscles
Chest and back: Tense chest, upper back, and shoulder blades
Stomach: Tense abdominal muscles
Legs and feet: Tense both thighs, calves, and feet simultaneously
Full body: Optional final tense of entire body, then full release

This version groups muscles efficiently without loss of benefit and is practical for daily use.

Step-by-step guide for beginners

Here is a detailed walkthrough using the 7-group protocol. Find a quiet space, wear comfortable clothing, and sit in a recliner or lie down.

Step 1: Arms (both dominant and non-dominant)

Sit comfortably or recline. Make tight fists with both hands and flex your forearms upward (like a bicep curl). Hold the tension for 5 to 10 seconds, noticing the squeeze in your hands, forearms, and biceps.

Release completely. Let your arms fall gently into your lap or by your sides. Spend 20 to 30 seconds noticing the contrast: the heaviness, warmth, and relaxation flowing through your arms. You may feel tingling or a pleasant heaviness.

Step 2: Face (forehead, eyes, nose, cheeks, jaw)

Tense all facial muscles at once: raise your eyebrows, squeeze your eyes shut, wrinkle your nose, clench your teeth, and press your lips together. Hold for 5 to 10 seconds.

Release. Feel your face soften, your jaw relax, your eyes rest gently. Your forehead becomes smooth. Notice the relaxation spreading across your face.

Step 3: Neck and shoulders

Shrug your shoulders up toward your ears and pull your chin slightly downward (or tilt your head back gently). Hold the tension for 5 to 10 seconds.

Release. Your shoulders drop, your neck lengthens. Feel the relaxation sinking into your neck, shoulders, and upper back.

Step 4: Chest and back

Take a deep breath in and hold it, expanding your chest. Simultaneously, draw your shoulder blades together by tightening your upper back. Hold for 5 to 10 seconds.

Release. Exhale slowly. Feel your chest expand with relaxation, your back settle.

Remaining steps: Continue with abdomen (tense by drawing your belly in, hold 5-10 seconds, release), legs and feet (tense both thighs and calves by flexing, curl your toes, hold 5-10 seconds, release), and full-body integration if desired.

Total time: 10 to 15 minutes for the full 7-group protocol.

For a complete 16-group protocol script, many therapists and apps provide free or low-cost guided recordings (see Tips section below).

Tips for using Progressive Muscle Relaxation effectively

1. Start with audio guidance

Most people find PMR much easier with a guided recording. Recommended free resources:

Insight Timer: Free PMR recordings, including 10-minute and 20-minute versions
UCLA Mindful: The UCLA Mindful app includes a PMR session
VA PTSD Coach: Free app from the U.S. Department of Veterans Affairs with PMR and other relaxation techniques
YouTube: Many therapists and universities offer free PMR videos

Listening to a recorded guide ensures proper pacing and removes the cognitive load of remembering which muscles to tense next.

2. Practice when calm

Do not wait for a panic attack to try PMR. Spend 1 to 2 weeks practicing PMR daily (or several times per week) when you are relaxed. This builds familiarity and makes the technique more accessible during stress. Think of it as training; you would not try a new meditation technique for the first time in the middle of a crisis.

3. Find a comfortable position

PMR works best lying down (on a bed or carpeted floor, with a pillow under your head) or reclining in a comfortable chair. Sitting upright is less ideal because you must maintain postural tension. If you must sit, use a chair with good back support.

4. Wear loose clothing

Tight clothing can interfere with your ability to tense and feel muscles properly. Wear loose, comfortable clothes or perform PMR before changing into sleepwear.

5. Do not tense injured muscles

If you have a recent strain, tear, or acute injury, skip tensing that muscle group. Use the "release-only" modification: simply relax that group without tensing first. For example, if you have a sore lower back, skip the abdomen tense-release and instead just notice the sensation in your abdomen during the rest period.

6. Pair with slow breathing

Breathing enhances PMR. Before or between muscle groups, take one slow, deep breath (count 4 in, count 6 out). Slow breathing activates the parasympathetic nervous system independently and works synergistically with muscle relaxation.

7. Practice consistently

PMR benefits accumulate with repetition. Aim for daily practice (10 to 15 minutes) for the first 1 to 2 weeks, then 3 to 5 times per week maintenance. Some people continue daily indefinitely because they find it deeply relaxing.

When Progressive Muscle Relaxation works best

PMR is particularly effective in these scenarios:

Pre-sleep anxiety: Anxiety that keeps you awake or fragmented sleep. PMR performed 30 to 60 minutes before bed (or in bed as your last waking activity) promotes sleep onset
Tension-related anxiety: Physical tension in neck, shoulders, jaw, abdomen that accompanies worry. PMR targets this somatic component directly
Anticipatory anxiety before a stressor: Public speaking, job interviews, medical procedures, exams. PMR done 30 to 60 minutes before (or the night before) decreases baseline arousal
Daily anxiety prevention practice: Regular PMR builds resilience and lowers your baseline stress level over time
Complementary tool in therapy: Alongside CBT, medication, or other treatments, PMR reinforces learning by grounding anxiety management in the body

Safety considerations and contraindications

PMR is very safe overall, but certain conditions warrant caution or modification:

Severe uncontrolled hypertension (high blood pressure)

Isometric muscle contractions (sustained tensing) can briefly elevate blood pressure. If you have severe uncontrolled hypertension, consult your physician before starting PMR. A safe modification is "release-only relaxation": skip the tensing step and simply notice relaxation in each muscle group without deliberate contraction. This avoids the brief BP spike while retaining much of the benefit.

Recent musculoskeletal injury

If you have acute muscle strain, joint injury, or post-surgical soreness, avoid tensing the affected area. You can still perform PMR on uninjured muscles. For example, after a rotator cuff injury, skip arm tensing but complete leg and face groups. Always check with your physician before starting PMR post-injury.

Severe chronic pain conditions

In some chronic pain conditions (fibromyalgia, complex regional pain syndrome), muscle tensing may exacerbate pain. If this is your situation, try release-only relaxation or consult a physical therapist to determine if PMR is appropriate for you.

Certain autonomic conditions

If you have a condition affecting your autonomic nervous system (e.g., dysautonomia, POTS, severe panic disorder with interoceptive sensitivity), start very slowly and under professional guidance. Some people with heightened body awareness find the intense somatic focus of PMR briefly anxiety-provoking; paired with therapist support or breathing, this usually resolves.

The Mayo Clinic, Cleveland Clinic, and NHS all note that PMR is safe for the general population, with these exceptions being rare and manageable.

Progressive Muscle Relaxation vs. other relaxation techniques

PMR is one of several evidence-based anxiety management techniques. Here is how it compares:

PMR vs. Breathing exercises (e.g., box breathing)

PMR: Longer (10 to 20 minutes), full-body focus, teaches somatic awareness
Breathing: Faster (5 minutes or less), portable, can be done anywhere
Best use: Use breathing for quick acute resets; use PMR for deeper, sustained relaxation
Combination: Many therapists recommend both; breathing can precede or accompany PMR

PMR vs. Grounding techniques (5-4-3-2-1, 3-3-3 rule)

PMR: Internal somatic focus, requires quiet, removes focus from environment
Grounding: Engages external senses, can be used in public without drawing attention
Best use: PMR for relaxation and sleep; grounding for acute anxiety in the moment
Combination: Grounding interrupts acute panic; PMR prevents panic escalation through regular practice

PMR vs. Meditation

PMR: Structured, body-centered, easier for people who struggle with "empty mind" meditation
Meditation: Can be more flexible, develops attention and present-moment awareness
Best use: Both are valuable; choose based on preference and context
Combination: Some people do PMR first to settle the body, then meditate

PMR vs. Exercise and movement (yoga, tai chi)

PMR: Passive relaxation, no cardiovascular demand
Exercise: Active, builds strength and aerobic capacity, mood-boosting via endorphins
Best use: PMR for relaxation and anxiety symptom management; exercise for anxiety prevention and overall health
Combination: Ideal; use exercise daily and PMR as needed for relaxation and sleep

Limits: Progressive Muscle Relaxation is a support tool, not a treatment

PMR is an effective coping skill and anxiety management technique, but it does not treat anxiety disorders on its own. Recognize when professional help is needed:

Generalized Anxiety Disorder (GAD): Persistent worry that PMR alone does not resolve requires cognitive-behavioral therapy, possibly medication
Panic Disorder: Repeated panic attacks require exposure therapy and/or medication, not just relaxation
Social Anxiety Disorder: Requires exposure therapy (gradual social engagement) and often medication
PTSD: Requires trauma-specific therapy (CPT, EMDR, trauma-focused CBT)
Anxiety with depression: Requires integrated treatment addressing both mood and anxiety
Anxiety persisting beyond 2 weeks despite daily PMR: A sign that professional evaluation is needed

First step: Contact your primary care provider, a community mental health center, or use SAMHSA (1-800-662-4357) to connect with therapists and psychiatrists. PMR is best integrated into a comprehensive treatment plan that may include therapy, medication, and lifestyle changes.

FAQ

Q: What is progressive muscle relaxation, and does it really work?

A: Progressive muscle relaxation is a technique where you systematically tense (5-10 seconds) and then release (20-30 seconds) each major muscle group in your body. A 2008 meta-analysis by Manzoni and colleagues reviewed 60 randomized controlled trials and found moderate anxiety reduction (effect size Cohen's d = 0.70). Research by McCallie (2006) and Conrad (2007) confirms PMR is effective for anxiety, tension headaches, insomnia, and procedural anxiety. However, it is a support tool, not a standalone treatment for anxiety disorders.

Q: How long should I practice progressive muscle relaxation?

A: A complete session takes 10 to 15 minutes (7-group abbreviated protocol) or 20 to 30 minutes (16-group traditional protocol). For best results, practice daily for 1 to 2 weeks, then 3 to 5 times per week. Beginners often benefit from longer sessions and guided recordings. As you become experienced, you can use abbreviated 10-minute versions.

Q: Can I do progressive muscle relaxation lying down?

A: Yes, lying down is actually ideal. Most people perform PMR on a bed, couch, or carpeted floor with a pillow under their head. Reclining in a comfortable chair is also excellent. Sitting upright is less ideal because you must maintain postural tension. Choose whatever position allows complete relaxation without falling asleep (unless you are using PMR specifically for sleep).

Q: What is the best time to do progressive muscle relaxation?

A: The best times depend on your goal. For sleep, do PMR 30 to 60 minutes before bed or as your last activity in bed. For daytime anxiety, practice in the morning or midday to build a calm baseline. For anxiety before a specific stressor (presentation, exam, appointment), do PMR 30 to 60 minutes before or the evening before. Daily practice (morning or evening) is ideal for ongoing anxiety prevention.

Q: Can progressive muscle relaxation lower blood pressure?

A: Regular PMR can modestly lower baseline blood pressure over time through consistent parasympathetic activation. However, a single session lowers anxiety and physical tension more than it lowers blood pressure. Important caution: the tensing phase of PMR can briefly elevate blood pressure due to isometric contraction. If you have severe uncontrolled hypertension, use "release-only relaxation" (skipping the tensing phase) or consult your physician first.

Q: Is progressive muscle relaxation safe during pregnancy?

A: Yes, PMR is safe during pregnancy. It is an excellent tool for managing pregnancy anxiety, insomnia, and body tension. Important modifications: (1) Avoid lying flat on your back after the first trimester; use a left-side-lying position or semi-reclining position instead. (2) Skip tensing the abdomen; instead, simply notice relaxation there without contraction. (3) Avoid very intense tensing; use 70 percent effort rather than maximum effort. Consult your obstetrician if you have specific concerns, especially if you have gestational diabetes or blood pressure complications.

Q: What if tensing a muscle hurts?

A: Do not tense that muscle. Use the release-only modification: simply rest and notice relaxation in that area without deliberately contracting it. This is safe and retains most of the benefit. Common scenarios: sore neck or shoulder (skip neck-shoulder tense), lower back pain (skip abdominal tense or do very gently), recent injury (skip the injured region entirely). If pain persists or worsens, consult a physical therapist or physician to rule out injury.

Q: How is progressive muscle relaxation different from stretching?

A: PMR and stretching are different. Stretching lengthens muscles and improves flexibility through sustained gentle lengthening (static stretch) or dynamic movement (dynamic stretch). PMR contracts muscles briefly and intensely, then releases, teaching your nervous system to shift into relaxation mode. Stretching is more of a physical fitness activity. PMR is a relaxation and anxiety management technique. You can combine both: stretch first to warm up muscles, then do PMR for relaxation.
