Here’s a question that sounds simple but opens up a real philosophical divide in how we think about the body: what is the skeleton for?
Feldenkrais practitioners have a clear answer. The skeleton is your primary support structure. Organize it well, align the bones so that gravitational force passes cleanly through them, and you can stand, sit, and move with minimal muscular effort. The muscles are free to do their actual job, which is to move you, rather than hold you up. The skeleton bears the weight. The muscles produce the motion.
It’s an elegant idea, and in many contexts it’s correct. But I think it tells only half the story. And the half it leaves out matters a great deal for the bodies I see in my practice.
The Feldenkrais view: skeleton as architecture
Moshe Feldenkrais was deeply influenced by engineering and physics. He was, after all, a physicist and a judo expert before he became a movement educator. His thinking about the skeleton reflects that background.
In the Feldenkrais model, efficient posture means transferring weight through the skeletal structure with minimal muscular effort. Think of a well-built column. If the segments are stacked cleanly, the column can bear tremendous load. Misalign those segments and you need external supports, guy-wires, buttresses, to keep the whole thing from toppling.
Your muscles, in this analogy, are the guy-wires. When your skeleton is poorly organized, your muscles have to work constantly just to keep you upright. Your neck extensors grip to keep your forward head from falling further. Your lower back muscles brace to compensate for an anteriorly tilted pelvis. Your hip flexors shorten to stabilize a pelvis that’s not sitting cleanly over the legs.
The Feldenkrais solution is to reorganize the skeleton. Find the alignment where bones stack cleanly, where gravity passes through the structure rather than pulling it apart. When you achieve this, the unnecessary muscular effort drops away. You feel lighter. You breathe more easily. Movement becomes fluid because the muscles are no longer doing double duty as both movers and structural supports.
This is beautiful thinking, and I’ve seen its practical effects. When I teach a client to find the skeletal support in standing, when their head finds its balance point over the spine and the spine finds its balance over the pelvis and the pelvis finds its balance over the feet, the reduction in muscular effort is immediate and often dramatic. People say things like “I didn’t know standing could feel this easy.”
Feldenkrais was right about this. Skeletal organization matters enormously. The extensors, the deep postural muscles that work against gravity, function best when the skeleton gives them a mechanical advantage. Misalign the skeleton and those extensors have to work overtime, often recruiting the larger, more superficial muscles as backup. That’s the pattern behind most of the chronic tension I see: big muscles doing the work of small muscles because the architecture doesn’t support efficient load transfer.
So far, so good. But here’s where I start to diverge.
The skeleton as living tissue
The Feldenkrais model treats the skeleton primarily as architecture. Bones are the beams and columns of the body. Organize them well and they’ll do their structural job.
But bones are not beams. They’re living tissue. And living tissue responds to its environment.
This is Wolff’s Law, described by Julius Wolff in the 19th century and confirmed by every bone biologist since: bone remodels in response to the mechanical loads placed upon it. Apply force to a bone and it lays down more mineral along the lines of that force, becoming denser and stronger. Remove force and the bone resorbs mineral, becoming thinner and weaker.
This is not a minor footnote. It’s a fundamental biological principle. Your bones are not static architecture. They’re responsive tissue that gets stronger when loaded and weaker when unloaded.
And that means the muscular forces acting on bones are not just incidental to movement. They’re essential to bone health. When muscles contract forcefully, they pull on bone via their fascial and tendinous attachments. That pulling is a mechanical stimulus. It tells the bone to strengthen. Remove that stimulus, reduce the muscular loading, and the bone weakens.
This is why astronauts lose bone density in space. It’s why prolonged bed rest leads to osteoporosis. It’s why weight-bearing exercise is the single most effective intervention for maintaining bone density as we age. The bones need to be loaded. Not just passively through gravity, but actively through muscular contraction.
The tension between the two views
Do you see the tension?
The Feldenkrais model says: organize the skeleton to minimize muscular effort. The biological reality says: bones need muscular loading to maintain their structural integrity.
If you optimize purely for skeletal organization, for minimal muscular effort in posture and movement, you may reduce the mechanical loading that bones depend on for their health. Taken to its logical extreme, the perfectly efficient skeleton would be a skeleton that’s barely being loaded by its muscles. And a skeleton that’s barely being loaded is a skeleton that’s losing density.
Now, I want to be fair. Feldenkrais practitioners are not telling people to stop moving or stop using their muscles. The method involves plenty of muscular engagement, just organized efficiently. And the reduction in unnecessary effort is genuinely valuable. Nobody benefits from chronic muscular bracing.
But I think there’s a blind spot in the model, or at least in how the model is sometimes applied. The emphasis on minimal effort can inadvertently devalue the role of muscular loading as a positive stimulus. It can create a framework where strength is seen as tension, where effort is always something to be reduced, where the ideal body is one that does the least work possible.
And for the bodies I see, many of which are under-loaded rather than over-loaded, that emphasis can miss what they actually need.
Modern bodies are under-loaded
Here’s the context that changes the equation.
Feldenkrais developed his method in a world where physical labor was still common, where people walked as their primary mode of transportation, where bodies received substantial mechanical loading as a matter of daily life. In that context, the problem really was excessive and disorganized muscular effort. People were overworking. They were grinding. They needed to learn ease and efficiency.
Many of the bodies that come to my practice are living in a different reality. They sit for ten or twelve hours a day. Their primary physical activity is walking from the car to the office. Their muscles are not overworked. They’re underworked. Their bones are not being excessively loaded. They’re being starved of the loading they need to maintain density and strength.
For these bodies, the message “reduce unnecessary muscular effort” can actually be harmful if it’s the only message they receive. What they need is not less effort but better-organized effort, and also more effort in certain specific ways. They need to load their skeleton intentionally, through resistance training, through weight-bearing movement, through activities that create the muscular forces that maintain bone health.
I see this pattern regularly: someone in their sixties who has been practicing Feldenkrais for several years. Beautiful movement quality. Exceptional awareness. They can feel subtleties in their body that most people would never notice. And they’ve been diagnosed with early-stage osteopenia, the precursor to osteoporosis.
Their Feldenkrais practice taught them to move with remarkable efficiency and ease. But efficiency and ease don’t build bone. Loading builds bone. They need to add resistance training to their practice, not to replace what Feldenkrais has given them, but to provide the mechanical stimulus that bones require. It’s like having a beautifully tuned engine but never actually driving the car uphill. The engine stays refined, but the chassis never gets the stress test it needs to stay strong.
This is not a failure of the Feldenkrais method. It’s a recognition of its scope. Feldenkrais is superb at teaching movement quality, coordination, and efficiency. It’s not designed to provide the muscular loading that bone remodeling requires. That’s a different input, and it needs to come from somewhere.
Both views are right
I want to be clear about where I land on this because I think nuance matters here more than taking sides.
The Feldenkrais view is right: skeletal organization is fundamental to efficient movement and posture. When the bones are well-arranged, the muscles can do their job with less wasted effort. Chronic muscular holding patterns are genuinely problematic, and learning to release them is valuable.
The biological view is also right: bones are living tissue that need mechanical loading to maintain their health, and muscular contraction is a primary source of that loading. Reducing muscular effort to the absolute minimum, if that were even possible, would be detrimental to bone health over time.
The question is not which view is correct. The question is what comes first.
And my answer, in practice, is that organization comes first.
You should organize the skeleton well. You should learn to stand, sit, walk, and move with good skeletal alignment and efficient muscular coordination. This is the foundation. Without it, loading the skeleton through resistance training or vigorous movement just reinforces dysfunctional patterns. You get stronger, yes, but you get stronger in the shape of your compensations. That’s how you end up with a strong, well-conditioned body that still hurts.
But organization alone is not enough. Once the skeleton is well-organized and the nervous system knows how to maintain that organization under load, then you need to load it. Deliberately, progressively, with appropriate intensity. Not to create tension, but to create the mechanical stimulus that bone and connective tissue need to thrive.
This is the sequence: organize first, then load. Awareness first, then intensity. Quality first, then quantity.
Neither half works well without the other.
What this looks like in practice
In my structural integration practice, the 12-session series addresses the organizational piece first. We systematically reorganize the fascial architecture so that the skeleton can find better alignment. The movement education component teaches the nervous system how to maintain that organization in daily life.
But I don’t stop there. After the series, or sometimes concurrently depending on the client, I encourage and support appropriate loading. This might mean a thoughtful resistance training program. It might mean specific loaded movements that target areas where the client needs more tissue resilience. It might mean recommending they work with a trainer or coach who understands how to build strength on top of good structure.
The goal is a body that is both well-organized and well-loaded. That moves with ease and also has the resilience to handle life’s demands. That has the skeletal efficiency Feldenkrais valued and the tissue robustness that biology requires.
I think of it as strength not in the gym sense of maximum force production, but in the broader sense of control, resilience, fine motor precision, and ease. You want a body that can be quiet when it should be quiet and powerful when it needs to be powerful. That can sit at a desk for an hour without accumulating tension and also carry groceries up three flights of stairs without bracing against itself.
That’s not just organization. It’s not just loading. It’s both.
The skeleton question goes deeper
This is, at its core, a question about what we think the body is. Is it a machine to be optimized for efficiency? A structure to be aligned in gravitational space? Or is it a living system that adapts to the demands placed on it and deteriorates when those demands disappear?
Feldenkrais leaned toward the mechanical-organizational view. Bones are architecture. Organize the architecture. Structural integration, at least as I practice it, holds the biological-adaptive view. Tissues are alive. They need appropriate stimulus.
But as I said, both are right. The body is both architecture and living tissue. It needs both organization and loading. And the most effective approach to working with it acknowledges both dimensions.
In my previous post about the common ground between Feldenkrais and SI, I talked about the agreements. This post begins the disagreements. Not to declare a winner, but to show where each approach has something the other lacks, and how bringing them together produces a more complete picture.
The next post in this series will explore another point of divergence: the question of tissue. What do we do when awareness alone isn’t enough to change a body that has physically remodeled around its patterns? That’s where structural intervention enters the conversation, and where the Feldenkrais model faces its most interesting challenge.
If you’re dealing with a body that feels well-organized but lacking in resilience, or strong but poorly organized, or somewhere in between, I’d welcome the chance to help you figure out what’s needed. You can book a session or consultation at rockurbody.com/book.
