On the one hand, it's a cliche; there's a big difference between knowing and doing. On the other hand, movement is almost universally taught in this culture by giving people what's needed to understand a movement, not create it. It won't work well; these are very different parts of the brain.

Truly natural movement, such that comes from our hindbrain unrestricted is considered the exception, superlative, the domain of the gifted and experts only.

There is another way; it is possible to teach the deeper motor centers more directly. Many coaches and teachers know this at a gut level, but are limited: by lack of specific and expressive language, and thorough knowledge of what is needed experientially to create the desired result. (Teachers need both the logical understanding and the knowledge of how to evoke the desired response. It's easy to get confused at that point.)
