Being perfect is not the goal
The goal is to be creative and adaptable given our constraints, history, and injuries.
Perfect mechanics—or a body without any injury, tension, or pain—does not in any way guarantee good movement. That's because movement doesn't happen in perfect joints, it happens in the brain, in how we construct our self-image, in how we relate to the environment, and in our skill in knowing where we are in space, how we time the sequence, and so on.
Movement relies not on a functioning hip joint, but on your sense of your own hip. You might have more or less ability in your hip than someone else, but I guarantee that the person who knows how their own hip moves will move more efficiently and more elegantly than someone without that awareness, regardless of injury or pain.
Easy movement comes from self-knowledge, not mechanics. You can have a perfect physical body and still move poorly if your timing is off, if you effort extra hard in your neck, or if you can't feel the force through your feet.
For example, I have slipped discs, a chronic injury in my right SI joint, and a nasty habit of tensing my jaw when I'm stressed. Plus, I have an aging (over 50!) body with ligaments that are definitely not those of a twenty-five year old. I am not going to "fix" any of this, but I am going to strategize to move with greater ease given these conditions. Feldenkrais doesn't mean you'll do every movement perfectly. It means you'll move along a continuum toward greater kinesthetic intelligence and vitality.
Each person takes their own unique path toward higher functioning. For me, the idea is not to fix my ligaments so my body is perfect. The idea is to become creative and adaptable, to work within the constraints of my flawed human existence.
It's a brain thing
Reorganizing neuromuscular patterns is an evolutionary strategy as old as human life. Having this possibility gives us the unique capacity to learn.
People tend to think Feldenkrais will "fix" their movement. It is not true. Feldenkrais will improve your ability find new strategies for your movement, which is not the same thing.
“Do one good movement and not twenty bad ones because if you do one good one, it is possible to do another one better. If you do twenty bad ones the twenty-first will also be bad, also the hundredth, and also the thousandth. Whoever does not have patience cannot learn.”
