Somatic exercises are slow, deliberate movements designed to retrain your brain’s control over your muscles. Unlike conventional exercise, which focuses on building strength or burning calories, somatic exercises target the connection between your nervous system and your body. The goal is to release chronically tight muscles by changing how your brain signals them, not by forcing them to stretch or relax from the outside.
The approach was developed by Thomas Hanna, a movement educator who coined the term “sensory motor amnesia” to describe what happens when muscles get stuck in habitual tension patterns. Over time, your brain can lose awareness of certain muscles, holding them tight without you realizing it. Somatic exercises reverse that process by bringing conscious attention back to how you move.
How Sensory Motor Amnesia Works
Your body is constantly learning movement patterns. The way you sit at a desk, carry a bag on one shoulder, or brace yourself during stress all become deeply ingrained habits. Eventually, these patterns become so automatic that your brain stops registering them as voluntary. The muscles involved stay partially contracted all the time, even when you’re trying to relax.
Hanna described this as sensory motor amnesia: the loss of both sensation and voluntary control that comes from years of unconscious muscle memory. It’s not that the muscles are damaged. It’s that the brain has essentially forgotten how to fully release them. This is why someone with chronic neck or back tightness can stretch repeatedly and still feel stiff. The problem isn’t in the muscle tissue; it’s in the signal the brain keeps sending to that tissue.
Why These Movements Affect the Nervous System
Somatic exercises work through two sensory systems your brain relies on constantly: interoception (your sense of what’s happening inside your body) and proprioception (your sense of where your body is in space). When you perform a slow, focused movement and pay close attention to the sensation of contracting and releasing a muscle, you activate areas of the brain responsible for planning movement, processing body awareness, and regulating the autonomic nervous system.
This matters because chronic muscle tension isn’t purely mechanical. Your autonomic nervous system, the system that controls your fight-or-flight response, directly influences muscle tone. When you’re stressed or anxious, your nervous system increases the baseline tension in your muscles through spinal reflexes, adjusting your posture in preparation for protective movement. Over months and years, this elevated tension becomes your new normal. Somatic exercises interrupt that loop by re-engaging the conscious, voluntary parts of your motor system and giving your brain updated sensory feedback about what those muscles are actually doing.
Pandiculation: The Core Technique
The signature movement pattern in somatic exercise is called pandiculation. Think of what a cat or dog does when it wakes up from a nap: it deliberately contracts its muscles in a big stretch, then slowly releases them. That instinctive process is pandiculation, and it’s fundamentally different from passive stretching.
In a typical somatic exercise, you first gently contract the tight muscle on purpose, then release it as slowly and smoothly as possible, paying attention to every part of the release. This three-part sequence (contract, slowly release, rest) is what retrains the brain. By voluntarily tightening a muscle you’re already holding tight, you force your brain to acknowledge it. Then, by controlling the release with extreme slowness, you teach your brain a new resting length for that muscle.
Static stretching, by contrast, is passive. You hold a position and wait for the muscle to lengthen, but your brain isn’t actively involved in the process. That’s why stretching often provides temporary relief that doesn’t last. Pandiculation demands engagement and sends sensory information directly to the brain, creating a more lasting change in muscle tone.
Two Foundational Movements
Most somatic routines begin with variations of two movements done lying on your back with your knees bent.
The Arch
Inhale into your lower belly and gently roll your pelvis forward so your lower back arches slightly off the floor. Your tailbone stays down. The focus is on feeling the contraction of your lower back muscles as they engage. When you’re ready, exhale and release those muscles as slowly and smoothly as you can, returning to a neutral position without clenching your abs to get there. The point isn’t the arch itself; it’s the quality of the slow release.
The Curl
Inhale, then slowly exhale as you flatten your lower back into the floor, tuck your chin, and lift your head toward your knees. Only curl as high as feels comfortable. Feel your abdominal muscles contracting to tilt your pelvis. Then release your abs as slowly as you can, letting them gradually lengthen as your head lowers back down. Again, the controlled release is the exercise.
These two movements target the muscles along the front and back of your torso, the ones most commonly locked in habitual tension from sitting, stress, or injury. They look simple, and they are. The challenge is in the slowness and attention, not in effort or range of motion.
The Three Major Schools
Somatic exercise isn’t a single method. It’s an umbrella term that covers several related approaches, each with a slightly different emphasis.
- Hanna Somatics focuses specifically on pandiculation to address sensory motor amnesia. Sessions often use the arch-and-curl type movements described above, and the practice is closely tied to chronic pain relief.
- The Feldenkrais Method uses an exploratory learning approach called “Awareness Through Movement,” where an instructor verbally guides you through movement sequences, usually while lying down to eliminate the effects of gravity. The goal is spontaneous, efficient movement that emerges from improved body awareness. A core principle is that thinking, feeling, sensing, and moving are all interconnected, so changing one changes the others.
- The Alexander Technique emphasizes conscious control over habitual movement patterns, especially in the earliest moments of initiating a movement. Practitioners learn to pause between deciding to move and actually moving, noticing automatic muscular reactions and redirecting them. Sessions typically involve chair work and table work, often with light-touch physical guidance from a teacher. The objective is controlled, functional movement rather than the spontaneous movement that Feldenkrais aims for.
All three share the same fundamental idea: that many physical problems stem from unconscious movement habits, and that bringing awareness to those habits can resolve them. The Alexander Technique has particularly strong evidence for back pain. A randomized controlled trial found that 24 lessons led to a 42% reduction in disability scores and an 86% reduction in days spent in pain after one year.
Evidence for Chronic Pain Relief
The most robust evidence for somatic exercises centers on chronic back and neck pain. A study of Hanna Somatic Education for low back and neck pain found striking results. Mean pain scores dropped from 3.3 out of 5 to 0.6 for low back pain, and from 3.1 to 0.6 for neck pain. Those reductions were statistically significant.
The practical effects were just as notable. Before the intervention, 53.5% of participants were using pain medication. Six months afterward, that number had dropped to 13.6%. For those with low back pain specifically, medication use dropped by 87.5%. Doctor visits for pain management fell by more than 80% for both low back and neck pain patients. These aren’t small improvements, and they persisted for at least six months after the intervention ended.
The pain relief from somatic exercises appears to come not from strengthening weak muscles or increasing flexibility in the traditional sense, but from resolving the underlying pattern of involuntary contraction that was causing pain in the first place. For people who have tried stretching, massage, or strengthening programs without lasting results, the neurological approach of somatics offers a different mechanism entirely.
How to Start a Practice
Somatic exercises are gentle enough that most people can begin on their own. A good starting point is 10 to 20 minutes, two to three times per week. As your body awareness improves, you can gradually increase both duration and frequency. Many people eventually practice daily, treating it like a morning routine to reset muscle tension.
A few principles will make your sessions more effective. First, move slowly. If you think you’re going slowly enough, go slower. The brain needs time to register what’s happening. Second, use minimal effort. You’re not trying to strengthen anything. The contractions should be gentle, at maybe 50% of your capacity or less. Third, pay attention to the release portion of every movement. The slow, controlled lengthening is where the neurological change happens. Fourth, do your exercises on a firm surface like the floor, not a soft bed or couch, so you can feel your body’s contact with the ground.
You should feel less tension and more ease of movement after a session, not sore or fatigued. If a movement causes sharp pain, you’re either using too much effort or the movement isn’t appropriate for your current situation. The entire approach is built on comfort and awareness, not pushing through resistance.
