Tension Release Exercises (TRE):
Shaking to Release Deep Trauma Stored in Muscles
Why Your Body Holds What Your Mind
Can’t Express
Most people think of stress as a
mental or emotional burden—racing thoughts, anxiety, agitation. But stress is
not just psychological; it is physiological. When something overwhelms
you—whether an argument, an accident, years of pressure, or childhood
adversity—your body reacts before your mind does.
Muscles contract. Breathing gets
shallow. The nervous system prepares for danger.
And when the threat passes… not all
of that tension disappears.
Over time, layers of unprocessed
stress can accumulate in the body like tight knots in a rope, creating
chronic pain, fatigue, irritability, and a sense of being “on edge.”
Tension Release Exercises (TRE) is a method created to address exactly this problem. Through a
series of simple movements that trigger natural neurogenic tremors, TRE helps
the body release deep-held muscular tension—especially in the psoas and pelvic
region—so the nervous system can reset, calm, and recover.
This article explains TRE from
beginner to expert level, grounded in science, real examples, practical steps,
and balanced evidence.
What Is TRE?
Tension & Trauma Releasing
Exercises (TRE) is a body-based technique created
by Dr. David Berceli, PhD. It consists of 7 simple exercises designed to
fatigue specific muscles so the body naturally enters a state of neurogenic
tremoring—gentle involuntary shaking.
Think of it as the body’s built-in
reset mechanism.
Just as animals shake after a threat
to release adrenaline and restore calm, TRE encourages humans to access the
same natural reflex.
In simple words:
TRE helps your body “shake off”
stress that was never fully released.
No special equipment. No special
training required for basic practice. Just natural physiology.
Intermediate Explanation: How Stress
Gets Stored in Muscles
When the brain detects danger, the autonomic
nervous system (ANS) activates the fight–flight–freeze response.
What happens physiologically?
- The psoas muscles contract
(preparing to run or protect vital organs).
- Shoulders lift and tighten.
- The diaphragm restricts.
- Cortisol and adrenaline surge.
- Fascia stiffens.
- Blood flow changes.
If the threat passes before the body
releases these changes, tension can remain "unfinished" in the
system.
The “Trauma Loop”
Chronic stress or trauma can lock a
person into a repeat cycle:
- Stressor triggers the nervous system
- Muscles contract
- Stress never gets discharged
- The nervous system remains hyperalert
- Muscles stay tight
- Tight muscles signal the brain that danger
continues
This loop becomes a “body memory,”
even years later.
TRE interrupts this loop by activating
the body’s natural tremoring response—releasing tension from the muscles and
resetting the nervous system.
Expert-Level Understanding:
Neuroscience Behind TRE
1. Psoas Muscle Activation
The psoas is the deep core muscle
connecting the spine to the legs. It is heavily involved in fight–flight
activation.
Chronic psoas contraction
contributes to:
- Lower-back pain
- Pelvic tightness
- Anxiety
- Postural issues
- Digestive problems
TRE specifically fatigues and then
safely tremors the psoas to release stored tension.
2. Fascia and Stress
Recent research shows that fascia
(the connective tissue network covering muscles) contracts under emotional stress.
Neurogenic tremors help:
- Improve fascia hydration
- Reduce stiffness
- Restore elasticity
This supports better mobility and
reduced pain.
3. Vagus Nerve & Parasympathetic
Activation
TRE has been observed to:
- Lower heart rate
- Activate vagal tone
- Reduce sympathetic (stress) activation
- Increase parasympathetic relaxation
This is similar to the feeling after
deep meditation or safe physical touch.
4. Tremors as a “Reset Button”
Neurogenic tremors:
- Discharge excess adrenaline
- Reduce cortisol
- Normalize ANS function
It’s not magic—it’s biology.
Scientific Foundations (With
Evidence)
TRE is rooted in established
physiological principles:
1. Animals Shake to Release Stress
Ethologists have long documented
tremoring in mammals after danger—wolves, dogs, antelopes, and more.
Humans have the same capacity, but
social conditioning often suppresses it.
2. Neurogenic tremors occur in
physical rehab
Physical therapists observe that
patients spontaneously tremor during muscle fatiguing routines.
3. Research Evidence (emerging but
promising)
Studies show TRE can:
- Reduce anxiety and tension (multiple small
studies)
- Improve heart rate variability (HRV)
- Reduce muscle guarding (sports medicine
findings)
- Assist trauma recovery when supervised
Important:
TRE is not yet an FDA-regulated or fully clinically standardized therapy;
evidence is growing but still limited. It should be approached as a
complementary practice, not a replacement for clinical trauma therapy.

alternatives
Who Should Avoid TRE or Use Caution
TRE is generally safe but should be
avoided or done only with a certified provider if you have:
- Severe trauma history (PTSD, C-PTSD)
- Active psychosis or bipolar mania
- Recent surgeries
- Pregnancy (specific modifications needed)
- Severe cardiovascular conditions
- Uncontrolled epilepsy
When in doubt, consult a certified
TRE provider.
Practical Real-Life Examples
1. Office Worker with Chronic
Tension
A 38-year-old accountant sits 10
hours a day.
Shoulders stiff. Lower back tight. Mind racing.
After 10 minutes of TRE, gentle leg
tremors begin. They move into hips and lower back. After the session, he feels
lighter, breathes deeper, and reports sleeping better.
2. Athlete After Intense Training
A runner experiences tight hip
flexors and glute tension.
TRE helps release micro-spasms and
reduces recovery time, similar to foam rolling but from the inside out.
3. Trauma Survivor (supervised)
A person with stored childhood
trauma may tremor in different body regions—legs, abdomen, diaphragm.
With a trained provider, tremors gradually release deep emotional tension while
ensuring safety and grounding.
Step-by-Step Beginner TRE Guide
Step 1 — Preparation
- Quiet place
- Yoga mat
- Comfortable clothing
- 10–15 minutes
Step 2 — Warm-Up Exercises (TRE’s
standard 7 steps)
(Simplified version)
- Ankle stretch
- Calf raise
- Leg stretch
- Wall sit
- Psoas stretches on the floor
- Knees elevated to trigger tremors
- Allow tremors to spread naturally
Step 3 — Allow Tremors to Begin
You may feel:
- Leg shaking
- Pelvic vibration
- Belly trembling
- Warmth or waves moving upward
Stay relaxed. Keep breathing.
Step 4 — Modulate Intensity
If tremors get too strong:
- Move legs closer together
- Reduce the arch in your back
- Pause and breathe
If tremors stop:
- Re-engage the psoas stretch
Step 5 — Ending the Session
Gently roll to your side, sit up
slowly, and notice how you feel.
Advanced Applications

By releasing deep pelvic and spinal
tension, TRE can help people with:
- Sciatica
- Lower-back pain
- TMJ tension
- Fibromyalgia (case-by-case)
3. TRE + Breathwork for Deeper
Nervous System Reset
Combining slow diaphragmatic
breathing enhances vagus nerve activation.
4. TRE in Professional Settings
Used by:
- Psychotherapists
- Physical therapists
- Somatic practitioners
- Sports trainers
Common Misconceptions About TRE
“Tremors mean trauma is leaving the
body.”
Not exactly. Tremors release
neuromuscular tension and shift the nervous system, but emotional processing is
separate.
“You must feel strong emotions for
TRE to work.”
Many people feel calm or
neutral—still effective.
“TRE replaces therapy.”
TRE is a complement, not a
substitute for mental health treatment when significant trauma exists.
“Tremors should be intense to be effective.”
Gentle tremors often provide the
most sustained benefits.
FAQs
Is shaking normal?
Yes, it is the natural neurogenic tremor response.
How often should I do TRE?
2–3 times per week is typical.
How long do results last?
With consistent practice, tension levels reduce over time.
Can children do TRE?
With guidance, yes—children naturally tremor more easily than adults.
TRE as a Pathway Back to Your Body
In a world full of stress, TRE
offers a simple yet profound method to reconnect with your body’s natural
healing mechanisms. By allowing the muscles to release tension and the nervous
system to reset, you can experience more clarity, calm, and resilience.
TRE is not magic—but it leverages
the powerful biology already inside you.
When practiced safely and
consistently, TRE becomes a tool for emotional balance, physical ease, and
nervous system recovery.
TRE uses natural shaking reflexes to
release deep muscular and nervous-system tension. It is grounded in physiology,
accessible for beginners, and offers advanced benefits for experienced users.
Evidence is promising but still developing.
Practical Tips
- Start slow—5–10 minutes is enough
- Practice in a quiet space
- Drink water afterward
- Stop if overwhelmed
- Work with a certified provider if you have
trauma
