This is possible, but I'm completely unfamiliar with any research on the topic, if there is any. That last paragraph of my comment above is pure guesswork, and I would love to see some data, if anyone can dig some out...

I remember some research indicating that muscles could be made to grow by just visualizing muscle workout, without any actual muscle movements. Its not quite the same to make muscles grow as to make (karate) movements more precise by visualizations. I would however have thought the muscle growth hypothesis much more unlikely than the karate training.

I do not have any references, and have no knowledge of the quality of the research done.
