TRE Exercises: How to Release Trauma and Tension Stored in Your Body

You know the feeling. The one that lives in your hips — that dull tightness that never quite goes away, no matter how much you stretch. The shoulders that climb toward your ears without you noticing. The chest that never fully expands, like something invisible is resting on it.

There's a low-grade vigilance that runs underneath your day. A readiness that never turns off. You go to sleep tired and wake up braced. You've tried breathing exercises. You journal. You talk to people you trust. And some of it helps — but the tension is still there, underneath the words and the insight, sitting in your body like an old debt.

That tension isn't a metaphor. It's not a mindset problem. It's physical — real muscular holding, shaped by real events, stored in real tissue. And thinking about it rarely shifts it.

TRE exercises are one of the most direct tools we have for addressing it at the source.

TRE stands for Tension and Trauma Releasing Exercises, a body-based practice developed by Dr. David Berceli, a somatic therapist and trauma specialist who worked for decades in conflict zones around the world.

Berceli noticed something consistent across different cultures and contexts: after extreme stress or threat, people naturally shook. Their bodies tremored. And when they were allowed to do so — when the shaking wasn't suppressed — they seemed to recover faster. The tremoring wasn't a symptom of distress. It was the discharge of it.

Animals demonstrate this clearly. Watch a gazelle that has just escaped a predator: once safe, it shakes. Visibly, fully, for several minutes — and then it grazes again, as if nothing happened. The nervous system discharged the activation energy it mobilised for survival, and moved on.

Humans do this too — or we used to. Somewhere along the way, we learned to suppress it. The shaking felt embarrassing, or frightening, or out of control. We held still. We stayed composed. And the activation never fully discharged.

The result is what most of us walk around with: chronic tension stored in the psoas muscle and the surrounding hip and leg structures. The psoas is sometimes called the “fight or flight muscle” — it's the deep hip flexor that initiates the fetal curl of the body under threat, pulling your knees toward your chest to protect your vital organs. Under chronic stress, it never fully lets go.

TRE reactivates the body's natural tremoring mechanism — gently, safely, and progressively — allowing that stored tension to finally move.

If the idea of intentionally inducing tremors sounds alarming, that's understandable. Most of us associate uncontrolled shaking with panic, illness, or overwhelm. But somatic tremoring — the kind TRE produces — is qualitatively different.

Anxiety shaking is driven by sympathetic activation: fast, erratic, accompanied by racing thoughts and a sense of dread. It's the body revving toward a danger it can't resolve.

TRE tremors are slow, oscillating, rhythmic. They feel more like vibration than shaking — a gentle quiver that moves through the hips, legs, and sometimes up into the torso. They aren't something you force; they're something you allow. The difference is fundamental: one is the nervous system in overdrive, the other is the nervous system completing its cycle and returning to baseline.

What TRE does, physiologically, is help discharge incomplete sympathetic activation. When your body mobilised for fight or flight — whether in response to a car accident ten years ago, a childhood that didn't feel safe, or the constant low-level stress of a demanding life — some of that energy got stuck. The activation completed, but the discharge didn't. TRE picks up where the body left off.

This is what makes TRE a body-based trauma release method rather than a top-down approach. You don't need to process the story. You don't need to understand the origins. You let the body do what it already knows how to do.

Your first session with TRE might feel like nothing much at all. That's normal. The body's tremoring mechanism has been suppressed for a long time — sometimes it takes a few sessions before it feels safe to activate again. Don't interpret the absence of visible tremors as failure. Something is still happening.

It might also feel like quite a lot. Some people experience strong shaking in their first session, warmth flooding their legs, or a wave of emotion — sometimes laughter, sometimes tears — that seems to come from nowhere. This is not a crisis. It is release. Let it move through.

Either way, the tremors may be subtle — a faint vibration in the inner thighs — or visibly pronounced. Both are equally valid expressions of the same process. The body regulates itself. You don't need to make the shaking bigger or smaller; you just need to let it happen.

A few practical notes: 10–15 minutes is plenty for a first session. Rest afterward — lie flat for several minutes and let the nervous system settle. Drink water. Be gentle with yourself for the rest of the day. You may feel noticeably calmer, or slightly tired. Both are common.

The effects of TRE are cumulative. Most people notice meaningful change in their baseline tension after 4–6 sessions. Once a week is a reasonable rhythm to start with.

TRE is well-suited for people carrying chronic tension, anxiety, sleep difficulties, or the accumulated stress of a demanding life. It's a practice, not a treatment — and as a practice, it's accessible to most people without any prior somatic experience.

It's also a good fit if you feel like you've done a lot of talk-based work and something still hasn't shifted. That's not a reflection on the quality of the work you've done — it's a reflection of where the tension lives. The body sometimes needs a body-based approach.

That said: if you're currently in active trauma processing, have a diagnosis of PTSD, or are new to somatic work and find the idea of uncontrolled physical sensations frightening, go slowly. The self-directed version of TRE is not always the right starting point. Working with a certified TRE provider first — someone who can guide the process and help you track your nervous system — is worth the investment if you have a complex trauma history.

The same applies if you have any significant hip, back, or knee injuries. TRE is gentle, but the positions do place load on these structures. Check with a healthcare provider if you have concerns.

The most important thing to understand about TRE is that it's not something you do to your body. It's something you allow your body to do. The tremoring mechanism was always there — it's factory-fitted, evolved over millions of years precisely for situations like the ones you find yourself in. TRE just removes the habit of suppression long enough for it to do its job.

You don't need to understand your trauma to release it. You don't need to relive it. You just need to lie on the floor, let your knees fall together, breathe, and get out of the way.
