this is a great thread. i am a musician in "regular life." i have been dealing with several sprains, to different parts of my hands since i started aikido. they get in the way sometimes when i need to play.
it often occurs to me that i am screwing up my hands by engaging in such frequent practice. i have also been looking for some balance in order to keep my body strong, as opposed to keeping my body constantly on the verge of injury.
i like this idea of strengh training outside of the dojo so prepare our bodies for all this crazy stuff we put it thru in the dojo. i might just need to hook that up.
