Re: new topic on training.
Just a quick note that the same strategies may be applied when you can't practice because of a serious injury. Watching class, seeing videos, reading books, meditation, visualizing the techniques, etc. Although nothing is the same as being in a dojo, you can also physically move through some techniques and exercises.
I know I'm doing a lot of practice with footwork, balance, and centering since I'm recovering from a badly broken collarbone. Oww.
