Have you ever tried changing a bodily habit?
Maybe it's trying to stop shrugging your shoulders, maybe it's trying to stop turning your feet outwards when you walk, maybe it's trying to stop curling up like a shrimp when you sleep.
You remind yourself that you've adjusted and feel a little better. Then you get distracted, and five minutes later you snap back to reality—and you're back to square one.
This isn't because you lack willpower. It's because your body's inertia is at work.
Inertia is an energy-saving mechanism of the nervous system.
The brain is the most energy-consuming organ in the human body. Although it only accounts for 21 TP3T of body weight, it consumes nearly 201 TP3T of the body's energy.
To maintain this energy balance, the brain has a very clever energy-saving strategy: automating repetitive action patterns.
Every action you repeatedly perform will gradually be encoded by your nervous system into an automated program—no longer requiring conscious control or consuming a lot of attention; just a trigger signal is all it takes for the program to execute automatically.
This is the essence of inertia: it's not that you choose to move this way, but that the nervous system, in order to conserve energy, makes the body automatically take the most familiar path.
How is inertia formed?
Each time you move in the same way, the corresponding neural connections in your nervous system are strengthened a little.
There's a saying in neuroscience: "Neurons that fire together are connected."
Repetition strengthens the connection. A stronger connection makes triggering easier. Easier triggering reduces the need for conscious control. Eventually, the pattern becomes so automatic that you are almost unaware of its existence.
Inertia is gradually etched into the nervous system during this process.
Several forms of body inertia
Postural inertia
The way you're sitting right now is almost certainly how you sit most often. Your pelvis is slightly tilted forward or backward, your spine is in a fixed curve, and your head is in a habitual position.
This posture isn't something you choose every time you sit down—it's a preset value automatically set by the nervous system based on the most frequently executed programs.
inertia of movement
The way you walk, the way you turn around, the way you reach for something—every action has a "most familiar version" that has been repeated thousands or tens of thousands of times.
This version may not be the most efficient or the least harmful, but it is the version that the nervous system is most familiar with and that is most energy-efficient.
Tight inertia
This is the most often overlooked, but perhaps the most important, type of bodily inertia.
Chronic stress, injury, and emotional repression—these keep certain parts of the body constantly tense. Initially, this tension has a cause—a protective response to some kind of threat. But gradually, the nervous system encodes this tension pattern, so even if the original threat has long since disappeared, the tension remains because it has become a preset value.
Many people experience neck and shoulder tension, lower back tightness, and chest tightness not because they have any current problems, but because of bodily inertia, which has allowed a once-useful protective mechanism to persist until now.
Why doesn't "reminding yourself" work?
This is the most frustrating part of changing the body's inertia.
You know you're shrugging, you remind yourself to let it go, and it does. Then you forget about it, and it comes back up.
This cycle tells you one thing: conscious reminders cannot directly change the automated programs already in the nervous system.
Changing bodily inertia doesn't rely on reminders, but on retraining—allowing the nervous system to establish new, stronger connections, strong enough to compete with and eventually replace the old ones.
This requires repetition, but not blind repetition—it is repetition with awareness, making the new sensations clearer than the old ones in each practice, and the new paths more familiar than the old ones.
How does Chanrou work with her body's inertia?
The gentle breeze does not resist inertia; it bypasses it.
Replace commands with perception
When you try to force your body to change its inertia with willpower, you are fighting against a deeply automated system—the most strenuous and inefficient way.
Chanrou's approach is to bypass the conscious control of the cerebral cortex and speak directly to a deeper level of the sensory system.
Use imagery to guide movement, allowing the body to naturally find new paths without conscious intervention. Let a sensation lead you, rather than letting an instruction command you to move—the neural activity generated by the two is completely different in depth and breadth.
Creating new sensory experiences
The reason why inertia is difficult to change is because old sensory experiences are too familiar.
Through three-dimensional spiral movements, Chanrou allows the body to experience sensations it has never felt before—an extension in a certain direction, a sense of space in a certain joint, and a sense of support that grows from the depths.
These new sensory experiences establish new connections in the nervous system. They don't replace the old connections, but rather strengthen them, giving the body a choice—not just the old automatic modes, but also a new, more efficient possibility.
Repeat, but with awareness
The gentle movements deepened gradually through rhythmic repetition.
This repetition is not mechanical—each repetition allows for a more nuanced perception of the same action, uncovering details missed the previous time, and deepening the nervous system's learning with each repetition.
This kind of conscious repetition is much more efficient at building new neural connections than mechanical repetition.
Give your body time
Changing automatic patterns in the nervous system takes time. It's not because the body learns slowly, but because old connections are strong, and new connections need sufficient repetition to compete with them.
The practice of Chanrou doesn't have a timetable of "you should change after a few classes". It simply provides new sensory experiences continuously, strengthens new neural connections, and then allows the body to slowly make the new pattern a new preset value at its own rhythm.
When the new mode becomes the preset value
This is the moment that most profoundly changes the body's inertia—not the moment you strive to do it, but the moment you suddenly realize that your body naturally does it without being reminded.
When walking, the gait naturally has a slight elasticity. When sitting, the spine naturally feels supported. When turning, the movement naturally originates from deep within.
It's not about willpower or reminders, but because the new connections in the nervous system have become so strong that they've become new inertia.
The old inertia has been replaced by the new inertia.
The body's inertia is the deepest wisdom of the nervous system—it protects you, so you don't have to relearn how to move every time.
But when that inertia no longer works for you, when it becomes an old pattern that limits you, you don't need to fight against it.
You just need to gradually make a new pattern more familiar than the old one.
